CR500 rod and Piston in KX500

[Paul]

About right, my pistons were $1200.00

This thread is way too funny. CR rods in a KX, raising ports, 600cc sleeves..... I wish I could effectively use the STOCK KX500's hp in terms of putting down usable traction

I compete against alcohol bikes with nitrous, 140 hp 600cc four cylinder bikes, 700cc zabel motors and so on. A stock KX 500 has become tame to me, this isn't your daddy's woods bike I'm building!!!

You should read some of the threads over @ Turbo Mustangs Nothing like 1000+ WHP 9 second daily drivers

 The only reason my KX500 isnt any faster is they guy riding it. If I could get him to improve the bike would fly.  This has been an interesting post to follow and I hope that someone will try the 92 mm piston and report back on the results.  Not all modifications work well in the long run.  But a bore increase alone should not have too many ill effects. I was wondering about how hard it will be to kick over ? Jetting should be no big deal, and watching the plug temp should be easy also.
