what is the piston clearance supposed to be on a vertex piston? it came with no instructions. same as wiseco or is cast different?

[AlisoBob]

Same as oem, somewhere between 0.002" to 0.0025", depending on how accurate your machine shop is....

If I remember correctly the instructions with my vertex said 28 for 500cc applications.

ive got it at 0.003 rigt now but feels way too tight by hand, i think ill open it up to 12- 15 what do you think? too much?

[AlisoBob]

Mine was 0.00225" 4 years ago.

No blow by.
No squeek.
No issues.

Lots of Duning..... pinned.

[teemtrubble]

THE BRIDGE SHOULD ALWAYS BE DONE REGARDLESS!

[dahondaboy]

i already relieved the bridge, i have 9 days till widowmaker and dont have it together yet. my crank seals and oil seals just came in tonite so i can have the thing ready to bolt in by this time tomorrow. i just got my swingarm back from being extended and it is nice! 65-3/4 " axle to axle fully extended. ill post pics when i have it all together. its at the last bore so i need it to just last 2 or three good hard runs, then it gets a glen'ed jug.
