I have a 2006 yamaha wolverine 450 and am thinking about getting the clutch redone for more low end power. Would a EPI clutch kit or sending in my sheave and having yamaha machine it be better?? I don't really care about more top end, just want more low end.

 

well i think as far as a clutch kit goes. have you changed your stock tires to bigger ones and if so what size and type.... weight of tires makes a difference.

i did the epi kit for bigger tires and it helps. but if i had to do over i would go the other way now that i have seen you can have the sheave done...

 

I thought about changing the stock 23" tires with 25" maxxis zilla tires. would just changing to a bigger tire without redoing the clutch make me loose power?

 

im sorry this is on the wolverine,,, but i have a 450 grizzly 07 and i am haveing trouble deciding on the sleeve machined or getting a clutch kit im running 27in mudlites
