Zero Knievel Posted June 13, 2008 Share Posted June 13, 2008 For all I can tell, the bike runs fine. Basically, I think all bikes have this....a rhythmic cycle kinda like THUMP, THUMP, THUMP, THUD. It's bad when the bike first starts but the motor is cold. Once it warms up, it's not that noticeable, but you can feel it through the handlebars if you have a good sense of touch. When it runs, you can sense it, but again, it doesn't sound like anything's broken. I've replaced the plugs this past winter. It sounded better after the new plugs than it did before. I think this is all in my head...imagining a sound to be more than it really is. Does everyone's 'Bird have this "rhythm" when it runs?

spicholy Posted June 13, 2008 Share Posted June 13, 2008 Does it stop when you pull in the clutch lever? Especially when cold. Mine makes a racquet when cold. Just the clutch assembley. Quote Link to comment Share on other sites More sharing options...

If you have a friend who rides, let him take it for a spin and see what he thinks. It might be all in your head, or not. Quote Link to comment Share on other sites More sharing options...
CxBXR Posted June 14, 2008 Share Posted June 14, 2008 If it happens at idle, it is common, some say clutch noise while others say balancers. Mine makes the same noise at a low idle & cold Quote Link to comment Share on other sites More sharing options...
Zero Knievel Posted June 14, 2008 Author Share Posted June 14, 2008 So far as I can tell, the sound is consistent regardless of clutch engagement. It's very noticeable when it's cold. Less so when it warms up. I think it's just my imagination getting the best of me. Quote Link to comment Share on other sites More sharing options...

cbrxxquad Posted June 15, 2008 Share Posted June 15, 2008 there are three adjustments to the counterbalancers to set the clearances between the gears. the rattle may be the slack in the gears. The manual has the procedure. Quote Link to comment Share on other sites More sharing options...
