drake Posted April 30, 2011 Report Share Posted April 30, 2011 I have a 2003 290, running rough is probably a bit of an exageration but it doesn't run buttery smooth. The revs don't really come down to quickly either and it surges a little. I have read this thread http://www.trialscentral.com/forums/topic/35972-sherco-290-09-revs-falling-slowly/ and given the carb a good clean and a new air filter.The ignition has also been retarded 4mm. Anyone have any suggestions, what could cause this. it's not to much of a problem, but i would rather it wasn't there Quote Link to comment Share on other sites More sharing options...
