: Clutch adjustments?

I have noticed of late that WindRider's clutch seems not to be completely engaging. I tried to start it a couple of weeks ago, and with it in gear and the clutch pulled all the way in, it wanted to lurch forward when I hit the start switch. And on several occasions, I have it running and drop into first (holding the clutch in), and it kind of "pops" into first with a slight lurch. Is this normal for our bikes? Is there an adjustment?

Thanks,

A slight learch is normal espically when the oil is cold. There are two different places to adjust the clutch - on on the handle bars and another close to the shift pedal.

Mine does it too... I believe this is what everyone is referring to when they talk about the coffee grinder noise/ symptom.

There are two fixes: One is to leave the bike on the centerstand (I usually forget) - if ya do that, ya almost never get the lurch.

The other is to squeeze the clutch lever while running and in neutral about 5 times. There was a kawasaki service bulletin that advised drilling some holes in the clutch basket to alleviate the symptoms - I may look up same bulletin and do the same when I get around to replacing the clutch.

It shouldn't lurch or clunk when putting it in gear. If it does, your clutch needs to be adjusted. As said previously, you can adjust it at the lever or there is an adjustment about half way down the frame downtube on the left side of the bike.

As for the "coffee grinder" noise, no amount of adjustment will fix that. You either have it or you don't. It is a definite noise, not a lurch or clunk. It happens when engaging the clutch in first gear from a dead start.
I believe it happens because the clutch plates release all at once and vibrate as they come together rather than slowly engaging as the clutch lever is released. It only happens when the oil is cold and sticky. Once warm, it goes away. The bulletin can be found in the Gallery as Dianna posted it some time ago. It involves drilling a spiral series of 1/16 holes in the clutch basket to allow the oil to drain better as the clutch spins.
