Ok so, first off i've had a 2 stroke 4 like six months now and i'm posotive i want a 4stroke. (not because i'm scared... i do alot of trail riding and foul alot of plugs), so are therev any weird things to look for when buying a 4t? do you have to rebuild a ttr 125's engine as much as i rebuilt my kx 60? (every 60 hours)basically anything about 4t's that you could tell me will be help! thx!
