New tri-z 310 kits

[TRITecate350]

I am building 310 kits for the Tri-z and will be opening up a preorder for the kit. The kit will include a sleeve/piston/gaskets for $300. I am going to give a discount($50) for those who preordered or buys a billet head. I am going to offer the kits installed for $500 with some machining done for even more performance. On the billet heads I gave a discount for preorder, I am not going to do that this time, a deposit will just insure you get one.
Here is some pics of the kit....


First we have the 310 sleeve, I made a few changes to the sleeve and performance should be greatly improved.

Here we have a cylinder that I cut the reedcage, exhaust, transfer ports off. With everything removed I am able to measure, and design a sleeve with the best port layout and will match the triz cylinder without much port matching.

Here we have a comparison of the stock 250 cylinder and the "hacked" cylinder w/sleeve. Just to give you an idea of how much bigger than stock it is.

Here is a finished 310 cylinder that is ready for porting....

I am still deciding what other modifications I will be doing for the 310 cylinders. I am building a jig that holds the cylinder in a mill to cut the intake side ports, also I am going to use that jig to machine the boost port in the rear of the cylinder. Also this is a direct bolt on...no case mods needed. There will be 4 bores to the kit, and pistons are from wiseco and will be available for the next 20 years at least.
The preorder will be opened up as soon as I have taken care of the billet heads.

If you have any questions feel free to ask.

[Billy Golightly]

Is it just my eyes or are the new transfer ports staggered height? Nice :)

[85ytz250n]

What all would you need to do the install/machining? Also for the entire topend treatment what would I be looking at for the coolhead and 310 kit?

[hadar]

Holy smokes! That is the shiznit, I got to get me a Z sometime soon. :drool:

[TRITecate350]

Your right Billy, the transfer closest to the exhaust is a little higher than the other transfers. This sleeve was based on the stock port layout, and that is why it was made like that. The new designed ports in the new sleeves, are all the same height with the exception of the boost port which is higher than all other ports. I redesigned the boost port and more than doubled its size.

As far as a price for everything...probably $600. Billet head, big bore kit. and all machine work/port matching/boring. I have not figured out what the exact cost will be as of right now.

Thats cheap for a 310, you guys with a z should jump on that. Compare it to a 250r 310 and you would have that much into it easy. Just a resleeve, bore and port match would run at least $500.

Is that like the 250r, where it starts out around 295 and works up to a 310 on its last bore?

[Billy Golightly]

They were staggered stock? Hmm, didn't know that! Guess I'll have to look at a Z cyl a little bit closer next time. Anyways your doing some pretty bad ass work here Sprock, I'm sure these will sell well.

[TRITecate350]

Hehe...I am getting confussed. I am having a hard time with measuring the cylinder, but the only port that is stagered is the right transfer next to the exhaust. Why Yamaha did this is beyond me, infact I think it would be stupid to design a cylinder like this. When a transfer or set of transfers open first, the highest presure of air/fuel will enter into the cylinder. The massive amount of exhaust flowing out the exhaust port at that time, will overpower some of the air/fuel and send it right out of the exhaust since both ports are so close to one another. I think that Yamaha did this to restrict power from the triz.

I have an aftermarket sleeved topend, and all the ports are the same height. My 310 kit will have all the transfers the same height except the boost port on the rear of the cylinder. I open the rear boost port first and point it at the center top of the bore, so the highest presure from the crankcase is used to help push stagnant exhaust out of the cylinder. It is kinda confusing..........but it works

At the stock bore size the engine will be 308cc, and at the final bore size it will be 325cc.... So if you wanted to call it a 330 kit you could, based on the other engine builders. Do you want me to call it a 330 kit? :naughty:

[Billy Golightly]

Yamaha was weird with these cylinders, Theres only one boyesen port in the intake too where they could have just as easily made 2.

Just out of curiousity since I've not looked at the transfer design on the Zs a whole lot and you have one already cut up :) Are they angled up, or are they horizontal? There might be some more power gain by flattening them out instead of pointing them towards the top...

[Kintore]

Sweet, looking really awesome

question- how long till we can buy one? preorder?

Thanks!

[MTS]

Put my name on the list for the whole Deal. Looks Killer.

[TRITecate350]

The ports are for the most part flat in the triz...and the big bore kit will have "big" boyesen ports.
I will probably opening up the preorders by Feb 1st. I am working on the jigs and setting up everything. I am in the middle of finishing the porting on the "proto-type" big bore kit for the testing. Should be interesting.
Here is another pic....

[nouseforaname90]

I'm considering a full kit. After I get a full report I'll decide :)

[Bryan Raffa]

You know dam well to put me on the list! as my new bike is just for this kit!

[gplarryv]

i already sent my deposit

[TRITecate350]

The preorders start now. They are $100 deposit which insures you will get a big bore kit and there will be an added benefit for those who preorder....
The pre-order will end on March 20th.

PRE ORDER HERE::Bounce

[MTS]

Cant wait...for mine

[TRITecate350]

I got your preorder.

[KASEY]

i am just curious,,,, would yuou benifit from a split exahust port,,,, maybe it would give longer ring life? just wondering,,,,,,,,,,,

[TRITecate350]

It probably wouldnt be much of a benefit on the life of the rings since the Tri-z exhaust isnt that wide. Also if I were to install a bridge in the middle like the honda, it would cut down on exhaust flow and I couldnt widen the port to get the flow back since the port is soo thin from the factory.

[TRITecate350]

I got 7 preorders soo far.....

[TRITecate350]

I only have a limited number of heads left and will probably have to shut down the preorders of "complete 330 kits" after the next 5 preorders. I will still have the "no head 330 kit" and bare bones kit available. I just wanted to let everyone know incase you were planning on waiting till last minute. When I run out of billet heads you will need to send your stock head to Yamahondaman or a local machine shop to remachine for the larger bore. Also, if you are using a stock head you might have a hard time getting a custom head gasket for it as well.

i've looked all over this post and can't find pic's of the billet head post some please ,cash in hand ready to order,thanks

[Bryan Raffa]

that I can do

[willcamach]

what type of gas will we need to run with this setup? will pump gas do, or will we have to run race gas???? also will any of the yamaha wrench reports be of any use with this setup or is unnessesary with the 310 sleeves port work?

[TRITecate350]

Parts of the wrench report are already built into this kit. You can run pump or race fuel depending on the dome you install with the kit.

[willcamach]

sounds good. i will be putting my deposit down for one next friday. thats pay day :).......... now what do i do for a cylinder do i have to search ebay for a used one or are you providing them for an extra fee.

[TRITecate350]

I have been buying used cylinders off of ebay and 3WW members and I have about 15 or so... For an extra $25 you can buy a cylinder from me, or provide your own.

[TRITecate350]

This is just a reminder, you have less than a week to send in your preorder money. I will be in Daytona Beach FL on Friday, so I will be away from the computer though the weekend unless I take my laptop.

[SpeedBump]

Bah! Florida....wether is TOO nice there. Stoppin in to check out the FTC Raggs? Talk to you later this week...as always!

The jugs look killer. Good job. I just hope they are NOT as fast as the OWNERS hope they are. Sucks having lots more quick machines out there.

[TRITecate350]

Here is an updated list of pre-orders. I will be shutting down the preorders tomarrow night. Thanks for all the preorders and continue to check out this thread for any updates and pictures of the progress.

21 preorders in all!:Bounce

[TRITecate350]

Pre-orders for the 330 kits are now closed.
Thanks for another sucessful pre-order program. I know this requires a lot of trust on the part of you guys, and appreciate your confidence. I believe this kit will be a huge increase in hp and torque and look forward to meeting a lot of you at trikefest this year.
I will be ordering the sleeves this week and should be receiving them in 6 weeks. As soon as the sleeves are in, I will be assembly line installing them and will have them done in May.
I will have pics along the way.

[TRITecate350]

I have set up a payment page for the remaining balance due on the big bore kits. I should have the sleeves in a couple weeks and every thing finished and shipped out by the end of the month.

Finish paying here (http://www.tecateconnection.com/completecheckoutbbkits.htm)

[MOTOMAX27]

You are the MAN !!!! I cant wait!!!:Bounce :Bounce

[MOTOMAX27]

How much HP do you think it will put out??:wondering

[TRITecate350]

I am going to guess it puts out 10-15 more horsepower with pipe/carb/reeds etc. I will try and dyno a stock and 330 kit on the dyno at Trikefest.

[TRITecate350]

I should have the sleeves with in a week and will be building the first 5 kits the weekend of June 3rd. Thanks for everyones patience.

[TRITecate350]

I am working on the big bore kits this weekend and hope to have the first 5-6 shipped out by the middle/end of next week. I had a minor set back which will delay me about 3-4 days. Pictured is an aluminum sleeve, I will be building 5 nikisiled versions of the big bore kit too. I will have more info on these soon. Pm me if you want one in Nikisil.

[viper]

well some of you guys already know that i purchased a bigbore kit from sprock and have seen it run but i wanted to post some comments about it to the others that are interested in them but havent bought one yet .

i had a very good running 250 cyl on it before and i really thought it would be hard to beat the performance of it but i was WRONG !!!!!!!
this bike wasent given a very nice break in process at all ....lol 2 heat cycles and to draggin i went ... the carb setup is way off but it still runs very hard ..

moshman,s bike also ran very well but he was having a slight electrical problem just before the drags but his bike runs very well also ..

in my oppinion there is alot more performance left to get out of my bike ..carb is way off and it has a very very conservative port job right now ( ported it in the trailer at tf ) ..i am going to have the porting finished , get it tuned then take it to the dyno and see what the lil girl will do then i will post results ..

in my oppinion to all you guys who are thinking of buying one of these cyl setups i wouldnt wate to long thay might be all gone .. i personally am going to buy another complete setup so when i hammer mine i can just swap it out and go again .. and i dont think you are going to get this much bang for your buck out of any other try-z cyl getting ported right now ......this kit is dirt cheap for what it performes like ... i could go on and on about it but i think i about covered it well enough ...........................just ask some of the guys that were at the trikefest drags how well it runs .....hope every tri-z guy that can will get one ......the honda guys dont like getting beat by a slow tri-z ..lol ...........................my.02 cents

[TRITecate350]

I have 7 kits done;
Shannon
Andrew
Sonny
Max
John
Mason
Your kits are on there way, and the extra one goes to the next in line.

[TRITecate350]

Sorry for the delay, I have had a string of problems.... Everyone who has ordered a big bore kit should have theirs by the end of next week. Most of them are pretty much waiting on the final honing for piston fitment.

[pickleweasel_00]

if you have an extra one, pm me... I would like to get one with a mild port job and a couple of the domes for the cool head you sent me

[TRITecate350]

Sorry for the wait guys, I am slowly but surely getting things done. These kits were much more labor intensive than I thought. Since I have been back from Trikefest, my father who is also my boss, has decided I have had loads of time off, and has been working me like crazy. And what spare time I do have seems to be split between big bore kits, family and just keeping things running smoothly with Sprock Racing. Thanks for everyones patience.....

[mike from long island]

Any updates on the kits?I dont need mine for a few weeks.Just checking in on ya.Hope your pop isnt working you toooo hard!!! LOL Keep up the good work.

[TRITecate350]

I have been shipping them out. I should have everyone who has paid for their kit shipped out sometime next week. Your the next one on the list for shipping Mike, so I would expect yours by next weekend.

[mike from long island]

Thanks for the update.I hope your not working yourself :crazy:

I am still waiting for the powder coater to finish.So it has worked out pretty good.Looking forward to getting the kit.Thank you for everything.Mike

[Hooligans]

Are all the kits spoken for? Or is there any left?

hey do you have any of these left i want am interested in getting one but let me know if you have any left.

[TRITecate350]

I have a few left that have not been claimed but I am running out of cylinders quickly and need more. If anyone can sell me some triz cylinders let me know.
I will be out of the harvest in 3 weeks and will be finishing the big bore kits. Then I will be on to the next project.

[TRITecate350]

I have this weekend off and will be finishing the big bore kits for everyone who has paid. Everyone who has not paid needs to pay in full by November 1st. I will be building the last kits the first weekend in November. I will have replacements parts available for the big bore kits and if someone wanted to make their own, I will give info on assembly. If you have preordered and have not paid please let me know when you will be paying, or we could work something out.

[MTS]

I got my sleave, n head, Give him some time, he puts more than 8hrs into 1 jug and he's a busy guy!! :p

[ATC-Eric]

I know he's alright, nothing happened. I talked to him the other day, all he is working on right now atv wise is the bigbore kits. Everything else is on hold.

[Killabee]

Be cool good work takes time!
Past experience tells me parts like this that are finished too quickly don't last long or don't perform well (junk!).
The anticipation is killing me!

[tri-Z ripper]

HE is a master at work all you inpatient guys should know when doing custom parts its not about the time its about the quality!

[Killabee]

hey corey,
I still have a spare jug with a broke sleeve skirt cant tell if the casting is still good if you want it I will ship it to ya! Let me know!

[icepick]

Corey,

Will you be shipping my kit out anytime soon?:(

[johnny's X]

Are there anymore of these kits to be had

[TRITecate350]

I have about 8 more kits to go out and then I am pretty much sold out of the kits, I will have a few for ebay that have heli-coils in them, or some other eye sore. I will let you guys know if I have anymore after all the pre-orders are gone.

I have replacement parts in-stock for the big bore kits if anyone has any issues etc, and will support these kits. Things are in the works for something even better, in about a year.

[Mosh]

Things are in the works for something even better, in about a year.

I cant wait for this.:)

[johnny's X]

Are we going to get a hint of what is coming in a year. Just a little something to get money in the savings account.

[TRITecate350]

Well, it will be for the triz. It isnt made of billet. It will probably cost near $600, and you will be able to see a proto-type @ trikefest if everything goes right....

[ATC-Eric]

Gots great news guys!!!

























Just got off the phone with Corey, he sent me a picture:






http://i109.photobucket.com/albums/n73/ericbs200/media1.jpg


































These will be in the mail in the next few days, they are completely bored and ported.
















Watch out for the mailman! :w00t:

[300rman]

SO does anyone have a ride report for us?

and someone has their kit listed for sale in the classifieds section BTW.

[MOTOMAX27]

Yes. I do have ride report and I will post up some pics of this weekend. Let me tell you guys something ITS FAST!!!! :naughty: :naughty:And I still need to jet it better. It was more than I thought and its so worth the money. Has anyone else put theres on?? What carb?? And Jetting??

[tri-Z ripper]

bump to this thread what is the latest news are these available corey? i am currently collecting all your parts for my Z!!

[TRITecate350]

I am completely done with the big bore kits. I have about 25 big bore kits out to customers and only had one customer that returned their kit for a full refund.

Most customers report:
Less vibration
Runs cooler
need larger front sprocket
about %50 more power

So far I know of about 5 trike who have about 10 weekends of riding and no issues with the kit. So far so good.

[TRITecate350]

I will probably do another pre-order this fall.

[TRITecate350]

Pre-Orders for this fall start now. Here is the link for more info and payment options.

C'mon guys, you need to be jumpin' on these things... 310 Tri-z, THATS BETTER THAN SEX!!!:naughty:

[HEAD09]

are you going offer just the coolhead????

[honda250sx]

Coolheads are coming. There will be colors availible as well. Stay tuned!

[TRITecate350]

I have more cool heads available, I just need to get some domes done, I still have some, just will run out soon.

[Blown 331]

This is way too much to read and I'm kinda confused between the pre-order discount, head etc etc. How much for jug and piston if I buy one this winter (as soon as I sell my Capri probably)? I don't want the head or extra port work. I actually just need a piston for the 250 but this isn't that much more by the time I have it bored etc. Do you need my stock jug or does that price include a core? I'll give you my stock jug if it gets the price down to justify. Let me know. Thanks.

[Mosh]

I cant quote you prices,But if you want the 310 kit,you almost, HAVE to have the coolhead, unless you want to spend money having a stock head machined to fit the larger piston.

[Blown 331]

I cant quote you prices,But if you want the 310 kit,you almost, HAVE to have the coolhead, unless you want to spend money having a stock head machined to fit the larger piston.

Gotchya, thanks. I was not aware of that. Like I said I did not read this whole thing. So it looks like $500 then.

[Mosh]

Still, a stellar deal.Comes with all gaskets and parts needed,plus the coolhead has re-useable seals,so no more 30 dollar headgaskets,and you also get a heavy duty base gasket too.Much stronger than stock.And if you ever go back to a 250,you can still use the coolhead,just switch domes.

[honda250sx]

Heads will be going to anodize this week via myself. They will be availible in black, red and blue this time.

[mike from long island]

IS it too late to get a head.I sold off my first head and bigbore to another member.But now,Think I would like to have another head....Possible another bigbore.I have extra cylinders too if needed.Thanks

[honda250sx]

Mike it is definetly is not to late. I believe if you have a good cylinder it can be done. I think there is something like 30 plus heads avail. I have 30 to anodize next week.

[mike from long island]

Mike it is definetly is not to late. I believe if you have a good cylinder it can be done. I think there is something like 30 plus heads avail. I have 30 to anodize next week.

Who should I try and contact about getting on the bigbore list?It has been a last minute decsion.I sold my last one to a member and have been kicking myself since.I know it went to a good home.But now building 2 Tri-Z's.I want a mild bigbore for one.

[ATC-Eric]

Hey Mike, Corey is lookin for every spare cylinder he can get his hands on.

I will mention it to him, he will be out of the fields here REAL soon, so he will be back on the site more often.


You shouldnt have a problem getting a bigbore kit.

[mike from long island]

Good to hear.I have a jug I can sell him and give him one of mine for the big bore kit... Thanks for the good news.Hows your big bore coming along?

[ATC-Eric]

Good to hear.I have a jug I can sell him and give him one of mine for the big bore kit... Thanks for the good news.Hows your big bore coming along?

We are about to hit it hard. We have everything to assemble the motor for testing, we really want to take it with us to Glamis.


I will be giving updates, if it runs, it will be within the next couple of weeks :)

[TRITecate350]

Please let me know asap if you want a big bore kit , I ordered extra sleeves but they are getting claimed fast. Also its $600 for everything, 450 for the big bore kit with no head, 300 for just the bare bones parts for assembly.

[tri-Z ripper]

yes please i want one i will send you my head with whatever i need for cash to get one please please please!!!

[The Goat]

I want a complete bigbore kit with coolhead and an extra sleeve or two depending upon cost of sleeves.

I've sent you a PM as well. thanks bud.

[ATC-Eric]

Got sleeves on order, will be rolling more kits out in the upcoming months.

I need cylinders! I would like them to have good threads, and no major damage. If you don't know whether yours qualifys or not, throw me a picture or two.
