Hi all, I’m a little new here and looking for some advice. I’ve got a 67 Yamaha yds3 that I’ve had for about a year and a half. It has an older restoration on it with a little over 5,000 miles. It’s always had a little clutch slippage. Previous owner told me the clutch started to slip when he put lower handle bars on it. I tried to adjust the clutch shortly after I purchased it and had it pretty good. I ran some motul oil in it for a short period of time and clutch started slipping again shortly after (mostly in higher rpm’s ) just went back to the 20/40 yamalube hoping that would help with the clutch. It actually seems to be a little worse now. Hoping for some suggestions or tips maybe even some adjustment recommendations? I’m hoping to not have to pull it all apart but I’m afraid that’s probably going to need to be done Any help would be greatly appreciated, Thanks, Brian
Seeing as how the clutch is mounted on the end of the crankshaft it would be best to remove the cover and have a look. Some riders sit at the traffic lights with the clutch lever pulled in and this helps to wear the plates ( not to mention that the oil pump is driven by the clutch and will pump no oil when clutch is disengaged) and thrust bearing. Open it up and have a good check of the plates, the basket, thrust bearing and springs. Let us know what you find.
Thanks Murdo, I’ll give it a look over the next week or so and see what we come come up with then. Brian
