Re: 929 slipping clutch or jumping sprocket? help
Since this is the second time you've asked, than surely you've looked at your chain and rear sprocket? Pull the front sprocket cover and inspect the sprocket?
If you're ready to change oil, or can save your oil in a super-clean container, pull the clutch cover, and inspect the discs and plates. If you don't have a manual, I can help you with the service limit specs of the discs, plates, and springs as I have an online one. Pay VERY close attention when you remove the plates and discs, don't change the order in which they came off. Sometimes the first and/or last clutch-disc is slightly different from the others.
If your rear sprocket looks anything like my last one, then that's your problem for sure!
