GR36ORY Posted July 18, 2017 Report Share Posted July 18, 2017 Hi all i seem to have a problem with my Sherco 125. It was running fine then on one ride when I went into 5th gear the engine wouldn't rev almost struggled to do anything and the engine breaking came on then I would drop into 4th and try go again but had the same issue. It wasn't until I dropped into 2nd or 1st that I could then get back up through the gears but when I get into 5th the same happens and I have to slow right back down to get into 2nd or 1st and the engine would return to its self. This has been working it's way through the gear and now 4th gets it and 3rd sometimes. The engine seems to die when you try to open the throttle in the gears and when it's slowing back down and you try to open the throttle it still has no live and burbles along Anyone had this before or may have an idea of what it could be? Any ideas would be appreciated thanks Quote Link to comment Share on other sites More sharing options...
copemech Posted July 18, 2017 Report Share Posted July 18, 2017 Sounds like you may be running out of fuel. What year bike and what carb? Quote Link to comment Share on other sites More sharing options...
lineaway Posted July 19, 2017 Report Share Posted July 19, 2017 Or a poor way of explaining a real burnt clutch. Quote Link to comment Share on other sites More sharing options...
GR36ORY Posted July 19, 2017 Author Report Share Posted July 19, 2017 Sherco 125 2007 and not sure what carb is on it. The clutch seems fine changes through out the gears below 4th fine and no problems up and down, it's the engine breaking from 5th and having to drop back down to 2nd that has the problem then the revs come back and you can get going again Quote Link to comment Share on other sites More sharing options...
GR36ORY Posted July 19, 2017 Author Report Share Posted July 19, 2017 Bike won't stay running with out the choke on even when warm. When you pull the clutch in, it will still drive in gear but if revved with clutch in, it will disengage the drive. When I come off the throttle it stays high revs. The tick over screw wasn't changing the engine note at all. Quote Link to comment Share on other sites More sharing options...
lineaway Posted July 19, 2017 Report Share Posted July 19, 2017 If it will not run unless the choke is on, the first thing would be a good carb clean. Secondly you need to check the fluid flows from the petcock and that the tank is actually clean inside. Quote Link to comment Share on other sites More sharing options...
