I'd seize my motor at 40:1 in my application. I run my Wiseco's cleared at .007, otherwise they seize, even with 32:1 Blendzall in C12. My CR500 is strapped to a oval track kart and run at WOT for extended periods of time pushing 8500 rpm's.

Dimples do go up, tab towards the back. I use an OEM Honda cable with my PWK. As far as power, I think some people are saying 80ish... not 100% sure though.

Here is a look at the CR500 section in Wiseco's catalog.



Here's their dirtbike catalog... CR500 stuff is at the bottom of page 5.

If I'm not mistaken, there is 2 more bores... the 636 series of wisecos (or maybe it's pro-x) go in 1/4 mil increments... should be able to get a 90.75 and a 91. Right?

edit: The increments for wiseco is 89.00, 89.25, 89.50, 89.75, 90.00, 90.50, and 91.00
