What's the cause of intermittent clutch chattering at idle?
Clutch or trans rattle?
Idle with the clutch lever pulled in?
bike's in neutral, clutch is out.
I get that too. I've heard it on a few bikes and have heard others more in the know than I say that it's pretty normal. Call it "character."
<---------------Remember, we ride bavarian tractors
Also, I agree with PBG that it's coming out of the trans and not the clutch
It seems to have stopped. I rode her into work today, and she seems to have stopped the sound. I prolly just need to change the oil ... but it has only been 600 miles since the last one ... hummm ....
How many RPM when you notice the noise?
My trans will make noise if I lower the idle to about 950 or so. Idle at 1100 and the trans is nice and quiet.
I would think that when in neutral, clutch released there isn't a whole lot in there that can chatter at you.
I thought this was the Bavarian tractor?
I agree though, the airhead is very agricultural. And I play with old john deere's.
Low idle and unbalanced carbs will make this chatter noise more pronounced.
The noise is caused by the uneven load on some of the free spinning gears on the output shaft as this shaft is standing still when the bike is parked. The other two shafts is spinning till you pull the clutch and then they will also come to a standstill and that is why the noise will stop.
Do not concern yourself with this, it is not even an indication that the gears is worn or loose as a brand new gearbox will also make similar noises.
That's a really good answer. Thank you as I have the same noise. Pull clutch in lovely and quiet, let it out, chatter, chatter!
