Top Tier Tri-z - REINCARNATED

Jeff, nice work with that exhaust connector

Why can't I send you some .250 6061 for this mount issue?? Why are there limitations??

Is this the one you needed about .1875 for (in that area) ?? Whats is in the way?? Can I mill down just a small area o the thickness you need??

I'm thinking this is a different issue, I'm not sure.... You are welcome to any material I have to share

Hmmm- gap one one side, not the other? so that BOSS on the cool head is apparently not centered (someone needs to rewrite a CNC program ) because those are straight (one plane) plates correct??

2 flat plates with a stainless washer inbetween to take up the loss?? Whats the loss 1mm - 2mm?? Is that an 8mm 0r 10mm bolt? I have various thickness aircraft washers in stainless, more 8mm ID than 10mm - your big lower mount may be 10mm??

loosen everything up jack up on the motor and put the bolt in

Steve, I may need to go .250. If thats the case. I already have the material. It just seems too thick. But hey whatever I guess. This is the same thing we talked about.

That exhaust looks mighty nice!! Wont be long now jeffro!

Been there done that. Motor doesn't budge. Put the stock head on. It lines right up. This is a Sprock head issue...

[Bryan Raffa]

get the drill bit out...... I wanna say I had this issue also but mine has a little play...

[honda250sx]

I just bought a piece of 3/16 thick aluminum on ebay. I will just have to make my own engine mounts. That's all!

[Dirtcrasher]

You crazy , you let <> .062 extra material bug you??

Were layed off ya know, free is for me

J/K - Whatever makes you happy, it's obviously been done 100&#37; up to date so whats a few more bucks.....

I did get the mill running and could have fly cut some for ya but I need to tram in my head and I don't have the dial indicator I need to do that with. You should have stuffed your pockets before the ax fell

[Bryan Raffa]

just drill the two top holes,, on the bottom of the hole,,,bigger it will let the mount raise.. got that

[Mosh]

It is NOT a Sprock head issue..
It is a Bigbore jug issue.

There is near .070" combination, taken off the top of the jug and bottom of the jug to get the port timing correct.
This lowers the jug, and the head.

The heads bolt up OEM on the 250cc engine..
Do as Raffa says..Slot the oem mount brackets with a dremmel and loosen the other bolts.
They will line up, and you will never notice, the slotting you did to the top brackets.
You have to slot all 3 holes about 1/16th of an inch each.

I did it on mine.

[honda250sx]

Thanks Rob. That makes sense.

I need to get an air filter like yours. Or I need to get creative on this intake!

[fattri-z]

Yeah just slot the holes a bigger a little bit at a time. You won't see any imperfection as the washers will cover the holes. I also noticed my KX125 head mounts have fair sized slots which is stock on that bike.

[Mosh]

I cant find that filter part # to save my Life Jeff.LOL

[honda250sx]

Its in this post RU1750. 2 7/16 (62mm) 4 inch long k&n. I got something in the works. Waiting for all the right pieces to get here!

I need to do something with the coolant overflow too.

[DeePa]

yeah when you have the big bore kit you need to do a little work on those mounts. If you had told sblt500r he would have taken care of it when he made them for you.
