arthurthomson Posted November 11, 2019 Report Share Posted November 11, 2019 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.

compactpete Posted November 11, 2019 Report Share Posted November 11, 2019 Welcome to the wonderful world of trials! Sounds very much like you need to clean out the carb, not a difficult job just a bit fiddly if you're not used to them. You'll also need to check the filter and air box are clean. Might be worth seeking advice from someone at your local club / practice venue, the trials community are very friendly and most will be glad to help. 1 1 Quote Link to comment Share on other sites More sharing options...
breagh Posted November 12, 2019 Report Share Posted November 12, 2019 Hi Arthur welcome from Fife The main stronghold in your area is the Bob MacGregor Trials academy at Dunlop which isn't too far away from you. They've got a site so check that out. Best man for help /advice in your area is Murdo MacPhail who helps out at the academy. All the regulars will know how to contact him. Cheers. 1 Quote Link to comment Share on other sites More sharing options...
arthurthomson Posted November 12, 2019 Author Report Share Posted November 12, 2019 (edited) Hi started the bike last night on full choke and after running for a minute the revves went quite high and the bike cut out does that help any and it won't start or even try unless I put the choke back on again. Really appreciate you helping a pure novice like myself. Edited November 12, 2019 by arthurthomson Quote Link to comment Share on other sites More sharing options...
b40rt Posted November 12, 2019 Report Share Posted November 12, 2019 Clean the carb before looking else where. If your not sure how, check the make and go onto YouTube, lots of good info there. Take your time when stripping the carb and take pictures if your not sure. 1 Quote Link to comment Share on other sites More sharing options...
