If you can't fix it then get a bigger hammer

wow nessy.I would stop right there.The 500 fujis are a stong motor but i dont know about 132 hp strong.I would be checking all internal tolerances yearly on that.Other than nitrous your probly maxed.If you like to build big hp your with the right brand.Polaris 800 big blocks and the xcr 800 and some of the most sought after blocks for high hp sleds.other than that mabey porting if not already done and i am assuming you are running pretty high comp already. good luck

no way, unless you spent major money modifying the engine. my 1991, piped, clutched and regular track does 85 mph.


1976 MERC ICE TWISTER, 340, piped
1975 KITTY CAT
1983 CROSS COUNTRY, 500cc piped, clutched
1998 XC700 RMK, piped, clutched
1998 XCF440


may not able to fix stupid, but you can modify it.

Id say take a tooth or two out of the bottom and youll probable see over 100, but itll just take you a little bit longer to get there.
