krisbgasgas Posted April 7, 2010 Report Share Posted April 7, 2010 I'm just tackling a little niggle i have with the bike. When i rev the bike the revs slowly die down. I'm thinking in the back of my mind that the bike is running too lean. I'm going to try dropping the needle clip down 1 to see if this makes a difference. BTW the bike has a Keihin carb fitted.

houseape1000 Posted April 7, 2010 Report Share Posted April 7, 2010 Could it be a flywheel weight ? Quote Link to comment Share on other sites More sharing options...
krisbgasgas Posted April 8, 2010 Author Report Share Posted April 8, 2010 i've had the casing off and i dont think there is a flywheel weight on there. i've changed the e clip on the throttle needle to 2nd from the bottom nad its made it a little better. if i do the bottom or middle clip it is quite rough when applying the throttle it bogs down likes its trying to die. The air screww is 2 1/2 turns out aswell. Quote Link to comment Share on other sites More sharing options...
krisbgasgas Posted April 10, 2010 Author Report Share Posted April 10, 2010 i may have sorted the problem. one of the jets in the carb is only a 40 and needs to be a 48 for the gas gas Quote Link to comment Share on other sites More sharing options...
