Its likely to be the carburetor float height setting, it should be set to 21mm Link to comment Share on other sites More sharing options...
Beef Supreme Posted July 19, 2008 Share Posted July 19, 2008 i'm trying to get almost the same bike working , what does yours rev to wide open ? Link to comment Share on other sites More sharing options...
dualsporter Posted July 19, 2008 Share Posted July 19, 2008 i've had a problem similar to yours. I would say its an adjustment to your floats , or your float valve is getting stuck. You may just need to replace your float valve. Link to comment Share on other sites More sharing options...
martdram Posted July 19, 2008 Share Posted July 19, 2008 hi mate just seen your question ,you have a float problem ,either its not set correctly or its sticking ,could also have a hole in it but thats rare..regards martin Link to comment Share on other sites More sharing options...
Rat Posted September 27, 2008 Share Posted September 27, 2008 Thanks I have the same problem. I'm waiting for a manual for the bike. The float height is 21mm, how is this measured? With the float hanging down or with the needle just touching the float? Link to comment Share on other sites More sharing options...

Measure wit the float just touching the needle and measure to the carb flange, not the gasket that sits thereon Link to comment Share on other sites More sharing options...
