Clutch Still Slipping
07/26/09 at 03:00:57

Hi all. New to this so bare with me. My clutch seemed to be slipping on my '87 Savage when cruising at speed and I twist the throttle. The bike shifts fine through the gears, but slips on acceleration in high gear. Using the Clymer Manual, I decided to replace the 6 friction and 5 steel plates along with the 4 springs (which were longer than the ones I took out). Clutch still slipping on acceleration in high gear! Anybody got any idea on this?

Sometimes issues that seem difficult can be really simple to resolve. I'm going to throw this out there because I had the same problem last year. Clutch was slipping when I opened throttle in 4th gear on my '87 and all it took was a simple clutch cable adjustment, and no more slip. I have to thank Tmack for his help with this during the Pa. run in September. Told him about the problem when I arrived at his house, and 10 minutes later it was taken care of. Seemed like he knew exactly how much play the cable needed.

We need that bit of play in the clutch lever. If there's no play, that may be the problem.

Re: Clutch Still Slipping Reply #5 - 07/26/09 at 15:21:23 If the belt is slipping, the vibration would be enough to rattle your teeth out. If tyhe front pulley is slipping, youll see bits of metal when you pull the cover.

Maybe the clutch rod inside the case?

Posts: 18	Re: Clutch Still Slipping Reply #10 - 07/27/09 at 02:55:13 I've adjusted the cable to where I have about a 1/4 inch of play in the cable to see if that helps. I don't know about the marks on the case, couldn't find any. My bike is a '87.

There was a post sometime earlier this month about this issue and the marks on the engine showing proper clutch play. But my money is on the clutch cable: too tight and it will slip, especially in high gear.

It seems to be doing fine but will test alittle more later. I think this was my problem though. I will do final adjustments on the cable before testing. Thanks for all the great info!

Ok..... it seems everyone does the hard way and adjusts so that the arm on the case has so much play. Well..... you really need to adjust so that the clutch starts to grab at a certain spot when releasing the clutch.

Yes, I know that the FSM says adjust the arm. But I also read somewhere in the book that the arm is the course adjustment and the fine adjust is at the handlebar lever. Always adjust the fine first... the golden rule.....

So, I find that when releasing the clutch on the LS650's, the clutch has to start to "grip" at about 3/4 to 1 inch out from the handlebar grip for best operation. PhotoJoe had his out farther, maybe 1 1/4 to 1 1/2 inch out.

Try this and get back to us....
