so what size carbs should i go with i am also planing on going with v-force 3 reeds, coolhead, a +4 stroker and mx/trial port and +4 timing... if this means anything .... what is better the X-over or boost ...also i have gold series chrome headers and fmf 50cal silencers, but want to change to T5's... i have only had the bike for a month and have not had the money for the mods being i had to buy the bike and also put a new topend in it when i got it.... as for the piston melting i havent been riding it, i ride it on and off trying to figure what the problem is but thats about it....the plug looks good so i dont think its lean...it is dark brown almost to dark and only seems to run bad in lowend...
