Hi my names Arthur and I'm new to trial bikes, in fact any bikes. Bought a 2003 Sherco 250cc the bike ran great the first couple of learning sessions but now it starts no bother when on full choke but when choke is put off the engine dies I have tried keeping it revving for a while but it still dies when you let the throttle off. orry I don't know muck about the mechanics of a bike but am keen to learn and your help would be much appreciated in solving this problem guys.
