Hi.I have recently bought a evo 250 factory and a pal has just bought 2014 evo 300.the 300 is lovely to ride.climbs muddy hills snowy, hills efortlessly.where as my bike just wants to spin to point where i cant even nearly get up the hill.I was hoping the bike didnt have a flywheel weight but i checked and it does.Has anybody any tips for making my bikes power more similar to the 300 without buying one!
Cheers ?
