Clutch help?
« on: August 04, 2010, 09:03:34 PM »
I recently rebuilt my 1977cb750f and while doing so I installed a Barnett clutch and Barnett HD springs.  The problem I am having is when riding the clutch seems to slip very bad.  Clutch lever has normal action and when pulled in the bike shifts fine, but when in gear and riding the clutch consistantly slips bad.  I socked the friction plates in oil prior to install.  I am using the Barnett clutch plates and steel rings.  Since the Barnett steel rings are not dimpled like the stock Honda steel rings I was thinking this could be the problem.  I tore the clutch apart and re installed everything using the stock steel (dimpled rings) and made sure I put the clutch pack back together correctly.  When installing the clutch lifter plate I broke it so I have not been able to retest for slippage.

Does anyone have any ideas.
Thanks

I'm far from an expert, as my clutch is in pieces right now... but I have heard about problems with synthetic oil.

Are you using synthetic?

Jeez, they were all sleeping!

My first guess is it wasn't adjusted properly, especially at the adjuster on the engine cover. Let us know when you're back together for a walk thru.

Sorry you learned the hard way about the lifter plate. You also know or lucked into the fact the clutch basket has to mesh into the clutch center. That's not your problem though.

Thanks for the reply MCRider.  I adjusted the clutch by following the manual and then did it again to make sure.  How do you recommend adjusting the clutch?

Yes, the lifter plate is a weak link and it as my own fault it broke.
Thanks.

er, by the manual. I'm assuming you loosened the cable fully first? Then set the adjsuter on the engine, then snugged the cable back up?

Otherwise, no specific reason for clutch slipping with new plates. Have to wait till its back together. There are anecdotes about some oils affecting it. Nothing I can hang a hat on though. Maybe others can?
