arthurthomson Report post Posted November 11 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 Report post Posted November 11 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 Share this post Link to post Share on other sites

arthurthomson Report post Posted November 12 (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 by arthurthomson Quote Share this post Link to post Share on other sites
b40rt Report post Posted November 12 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 Share this post Link to post Share on other sites
splatered stu Report post Posted November 13 watch these video's first and things will make sense.all of Jim Snells video's are worth watching even if you don't own a gas gas.clean it well BEFORE taking anything apart and use wd 40 to get the rubbers moving when installing/extracting the carb.less likely to get a faulty seal or to get frustrated and do damage that way....Some guys rip stuff apart dry with dirt everywhere and end up doing more harm than good to the bike.make sure you have the proper screwdriver and not a dollar store wonder driver....calm and cool wins the race. good luck! 1 Quote Share this post Link to post Share on other sites

splatered stu Report post Posted November 15 (edited) pretty much.my favorite part was when i went to my garage and saw my bike was not that dirty or ran that rough....for a newbie it does have a lot of information and answers as long as you tune out the part where he talks.finding an awesome line through bullsheet is after all the essence of what trials is about no? i think the haywire and zip straps said it all anyway..
