_Wilson_™ 6,567 Posted March 20 I believe 2006 was the year carbs ended for those and fuel injection took over.... from what ive been reading the rubber diaphragm... might just be what the problem is... have you checked it for damage (pinched or ripped) @Mac102004 thoughts ? 1 Share this post Link to post Share on other sites

M_goerler 8 Posted March 20 I thought might be the cam issue read about but is got 140 psi compresssion Share this post Link to post Share on other sites
toodeep 1,758 Posted March 20 Cam was my first thought after the carb checked out. 140 is a high number since they have and auto decompression. A common thing is the bearing holder on the rear of the camshaft will go bad and letthe cam move around. That changes valve clearances and usally just makes it a dog when trying to ride it (1/2 throttle is all i has). Worn cam lobes will also do about the same. If you pull the very top cover off you can pull the lifters and see the cam (that will let you know if the lobes are wearing down). If those look good loosen the camchain adjuster and see if you can move the cam with a small screwdriver. 3 Share this post Link to post Share on other sites
