Fast Tri Z at Pismo Dunes Memorial weekend

[250R4life]

hey I went to pismo dunes just this past weekend, and if you all dont know I think I posted it I sold my 86R. Anyway everyone at our camp had honda and yamaha 450's and they were talking alot of stuff about how fast they are. So we all get in the truck and on the quads and ride out to the drag strip. We saw 450 beating this and 450's beating that, then we see this Yamaha Tri Z pull up to the drag strip and keep in mind it had regular sand tires, no swing arm, didnt have a chromed out motor or drag pipe or anything refering to make it think its fast it was just a regular Tri Z but it wasnt a pos it was nice. So we see this tri Z pull up and I was thinking man these 450 are going to spank this trike and I am a trike fan, and when they took off the 450 got it out of the hole and then that was about it for the 450's that trike was gone all the way down the drag strip. So I told my friend Jacob (and he is a really good racer and he weights about 130lb's) look whose spanking those 450's jake whats up I thought you said that those 2 stroke trikes were fast in the day but not anymore. My friend jacob goes and races that Tri Z and what do * know he gets beat by about 5 to 6 bike lengths and he comes back and I said what happen did that old trike take that new 450 or what, he said man I havent seen a trike that ran like that so my friend said hey I am going to race that trike on bobs quad( bob has a 450 with Sparks pipe, 190 main jet, airbox, port and polished head and a stage 2 hot cam in his honda 450) So jacob goes out there thinking that trike has nothing against this 450 and what do you know that trike sure in happen to beat that 450 by about 4 bike lengths. So what I am saying is did anyone see or does anyone own that bike because it was fast and it looked like your everyday regular 3 wheeler but it ran better that those 450's today.

:Bounce :w00t: I just love stories like that. :TrikesOwn

[Yardbird]

Great story.........Classic!

[NOS_350X]

Last time i was at pismo i saw a z with about a +12 swinger, and 22" haulers, that thing was keepin the front wheel off the ground all the way up comp. It just shows you that the trikes can hang witht he big boys still.

[03 ORANGE SHEE]

i thought all z's run like that, mine does! :p

[Semo Tri Z]

I have to agree!! I thought all Tri Z's ran that way. I know mine will haul ***. I have beat ALOT of big quads, stock and modified.

[1984kxtTECATE]

Im headed out to the sand september 17th, Im gonna have to give a report now that im gonna have the yamaha wrench mod motor, defiantly curious to see what it will do.

[Mr. Sandman]

A fast Tri-Z? Must have been something wrong with it. :D

[Rex Karz]

Did the Tri-z make it back to the beach?

[hrc85250r]

wow, that beast must have some SERIOUS prting done to it with a 40mm carb on it... did it have a drag pipe on it???

[max]

I THINK ALL THE 450 STUFF IS OVER RATED. ALL THOUGH I WOULD DEFINATELY ROCK ONE. :p

[firefirefire90]

I will have to get some pics of my friends tri-z next to the R and 200x. Man, west coast swinger, or at least it has the sticker. Fresh motor with a BIG BIG BIG BOrE kit on it. Shaved head, drag pipe. Oh man, she looks so scary, im only allowed to sit on her. Haha. wish the 250R could keep up with that Z, the 250 only has a dink 275cc motor an stock carb. I think it has diff jet. UNI filter though. An some wierd tail pipe. Right now that Z aint running. BAD gas in the tank for sitting for 5 months. Dumb people my friends are.

[twgranger]

You guys under rate the tri-z. If you rode one you would know how fast they are. They are not as slow as everyone says.

[firefirefire90]

stock for stock, they are dangerously slow, a Nice mod will do the trick. The only fastest stock trike is the kawie 250 86-87 model. Then the 250r , then the Z. But when mods come, its anyones game.

[westcoast TRI-Z]

You guys under rate the tri-z. If you rode one you would know how fast they are. They are not as slow as everyone says.

Agreed, they have buttloads of low end power, which makes great for acceleration. I'm satisfied with its speed, even if it does top out a 65 (from what people have said) that's plenty for me. I have a gps, maybe i should go try it out :naughty:

Go for it!

I am a big fan of the Tri-Z, it may not be the fastest track bike, but it was a great overall serious fun bike and easy to control. Thanks to being a 2-stroke, big power is always possible with mods if you want it also. And it was also the coolest looking trike ever made.

I go out of my way to smoke every 4-stroke in sight when I take out my CR250R, I consider it my mission. Long live 2-strokes! :beer

[1984kxtTECATE]

Mods to the motor does not make any bike faster, only gearing. Mods will only impact acceleration. BTW the kawi is not the fastest trike, Tiger 500 is that I know of. I will glady take acceleration over speed, goin through sand trails you'll never hit 60mph, you want good useable power which the tri-z delivers. Stock or modded. (I also dont consider 65mph slow either)


Did the Tri-z make it back to the beach?

I hope to god your not talkin about the trike rampage, I have a good feeling I am always going to relive that memorie. :(

[firefirefire90]

sorry bout that, i guess i like top speed rather than acceleration...Mods will make it faster wont it? You do need that gearing to. You are correct. I was talking about a 250cc trike. I only know of one person on this board with a tiger 500, and that is speedbump.

[Aussieboy1]

Well l have three triz 85's The main one that l ride was a racer here in NZ. I weigh about 280 pounds. I blew off a 450 quad last month he was not impressed. Then l told him that l paid $1000 bucks NZ,, that set him off more he said he had paid $15500 for his bike. I offered him a ride. He then carried on about how trikes were dangerous and that. I just smiled and left...

[Kintore]

Aint that the truth! Im modding mine only with a pipe and filter. Dont want to take away from all the bottom end:)

Im glad the Z was out in the dunes and doing well!

[wolfspider]

man i get tired of people slagging down tri z`s, i`ve had 3 and 2 250r`s, 2 of the tri z were stock and hauled ass when they were brand new, firefirefire90 have you ridden a stock fresh motored tri z? i`ve been riding 4 twenty years on trikes and all the 250 two strokes are fast no matter what colour they are. :rolleyes:

[edog]

I want one bad now.lol

Should have told him his 450 was more of a time bomb :lol: but the quad people hate it when a trike goes rolling past.

[OldSchoolin86]

If a Z is dangerously slow what do you call your trike? Comments like this make me believe you've never rode a stock Z.

[Semo Tri Z]

I don't understand where everyone gets this Tri Z's are slow. I have raced Tecate's, 250r's stock and modified and i haven't been outrun by a another trike yet. If you can get enough feul and air through a Z it will run as fast as you wanna go.

[OldSchoolin86]

Mods to the motor does not make any bike faster, only gearing. Mods will only impact acceleration. BTW the kawi is not the fastest trike, Tiger 500 is that I know of.

Not true. Proper mods will give you more RPM's and that will gain you a little more speed then I think you're giving it credit. You can gain RPM's by cam changes, carbs, porting and ignition too (4-stroke refence). As an example you can gain 8-10 mph in a Z if you can raise the rpm's another 1000rpm.

[edog]

What is redline for a Z?How would you gain 10 hp on a Z?

[1984kxtTECATE]

Oops, I should have thought of that. I see where your comin from, but I figured you will gain better speed by increasing the power and doing a gearing change.

I would do the wrench report mods, different pipe and carb. It wouldnt be that hard to accomplish.

[slothminx]

oldschoolin said that you will gain 8-10 MPH!! not hp

hmm 1984kxtTECATE gaining "better"speed ?? if you increase the rpm's at which the tri-z will still pull at. you can keep your stock gearing (good acceleration and low end grunt) and rev it higher in 5th(or 6th) to get the top speed you want.

if you increased the power but not allowing the Z to rev higher you can "cancel" out the trade off of more top speed, acceleration lost.

What OSin86 was suggesting is that you port the Z to allow it to breath better at high revs but not so drastic that you lose low end. That way it is a win win situation. you get same probably more acceleration, and you get your top end speed. Really it comes down to personal preferance and $$ they both basically do the same thing and without trying it you cant say which would be better.

About carbs. you only need to get a bigger diameter carb at a certain point. if you engine is being choked by the size of the intake port(four stroke) adding a bigger carb will do NOTHING but.. if you engine is being choked by the ID of the carb then yes a bigger carb will let that baby breath better you only need to replace the carb if thats the thing restricting the engine

sorry to go on a bit but i hope ive explained what i was trying to say :TrikesOwn

[bootheeltri-z]

Me and semo one day wanted to see how fast his z would run and my 1993 Cheverolet could not stay next to him over 80 mph. I know its hard to believe but i was driving the truck. So now i'v got a tri z and it will run close to his and we took them to the drag races i didnt do so well , i had only had my bike 3 weeks, but semo was smoking bikes left and right . I know without a doubt that with a couple mods that our bikes will be hard to touch. i cant keep my front end down so i'm going to have my swinger stretched. But a tri-z is not slow by no means. Just get one and see for yourself

[Darius1502]

I have two trikes a 86 Tri z and a 86 250R.

In the mid to upper the R hits harder

In the low to mid the Z hits alot harder.

Both are very fast...the Z just has a different powerband.

Z's are awesome and in my opinion the Z is a better ride. Longer, more comofortable. much more versitile engine. My R is stock and its just a mid range motor.

I have experience with long powerbands. My Quadzilla has a mile wide powerband, my two stroke KTM 550 dirt bike...same thing. The Tri Z has a great powerband for a 250 and think the motor is better, actually much better than the R's.

It is just as fast and makes more usable power across a wider range. Got it!!??

[firefirefire90]

You are alll correct, and i appologize. I know a tri-z would beat my 200x and i totaly agree with that. I have only ridden modded tri-z's and 250Rs...nothing stock. Haha i guess i was speaking outa my ass. sorry.

[OldSchoolin86]

Haha i guess i was speaking outa my ass. sorry.
No worries, we're getting used to it. :lol:

[SpeedBump]

Oops!
ErectorDale has them now. Had to unload them. Sometimes you gotta take the "deal". They are in good hands and will be making an appearance at TF06.

As for mods and speed...Mods WILL give more speed with or without different gearing. Porting/carb/pipe will give more HP and more rpms. Both will give more speed AND acceleration.

[kloby]

I love the sleepers. It is nice to have something nice to show off. But its better to say you beat something that everyone else THINKS is fast with your beater that IS fast. :lol:

[Dammit!]

Well I'm still slowly working on it but, my R has TONS more power than my Z at this point. It's not even close. The Z alledgedly has a 300 kit in it but I've been skeptical of that since day one. My R is ported, pipe, carb, rad valve, filter blah blah blah. The Z I just don't know. Stock pipe. It had a stock carb on it with I think stock jetting (another clue that it has no 300 kit). Now I've got the 34mm flat slide carb off my R on there with a clamp-on Uni. Taking it out for testing/jetting this weekend. If that goes well I'm throwing some new bearings in it and a couple other odds and ends and heading for Glamis the following weekend since my R is on the bench with a cracked center case.

Sooner or later (smart money is on later) I want to do the YZ powervalve mod to it with some good porting and even bigger carb. That ought to wake it up! BRRAAAPPP! :w00t:

[westcoast TRI-Z]

An old thread. No matter to me though, I just love reading about a good Tri-z wipping up on the four-fitties!:beer :TrikesOwn :lol:

[Bryan Raffa]

i thought all z's run like that, mine does! :p


I thought that too!! mine does also!

[mnnmaz]

What is the stock sproket size for the 85 triz? I currently have a 12 in the front.

[Bryan Raffa]

its a 13..

[mnnmaz]

Do you know the rear also? Sorry to bother!

[Bryan Raffa]

its a 44... not a problem!

BLING on that gas tank! That is a nice looking Z

[super90]

This is a 2yr old thread? Why are so many of these coming back to life? :confused:

[Dirtcrasher]

Maybe it's because somedays 3WW gets boring... No offence anyone, I still love it here :)

[LonesomeTriZ]

I like to see what was going on back then.

[icepick]

It makes me feel younger.:D

[Shawn72]

Here's a news flash..........................................A 250 2 stroke competition race engine is a fast son-of-a-B****. I restored an 86 TRI-Z. It's only slightly modified and I kicked those 450's asses!!! It's not an illusion, it's just that your TRI-Z hauls ass. God forbid I had a Tecate!!!!!

Can I get a witness?

[El'Capitan]

wheres my shovel, seems like were diggin up some long dead threads :beer

[Tryzeedudeman]

The tri z is the most comfortable, best looking, and by far has the most low end of all three. Top end sucks, without the mods that is. Oh ya, did i say they are the best looking too :)

[Yamahondaman]

[gaukel350x]

Ya I'm getting a tecate, top end is what I need. I can always get pipes and other little stuff to help the bottom end.
