My 66 Spitfire clutch was slipping a bit on acceleration so I changed the clutch. I replaced all of the plates and I installed a new MAP cover plate. It is better now, but it still slips. I went back and rechecked everything and I can't find anything wrong except that it still slips. The only thing that I can think of at this point is to go back in and tighten the clutch cover plate screws a few more turns. Does that sound like a good plan? Thanks, Doc

Check to ensure you have slack on the pushrod first. Then slack at the lever second.
If it is not an adjustment issue then chances are it will be in the clutch itself somewhere.

Seems strange to have to same problem after changing the pack,- I would be having a really good look at the rigging.

How does the clutch lever action feel ?

All the best with it..

first thing I would check is that you have a bit of free play in the push rod mechanism (when the clutch is out) ..you can tighten the springs all you want but if there is no clearance in the push rod you will be wasting your time, first things first

I did adjust the center nut on the cover plate using the instructions that came from MAP. They said to tighten it down until the free play is gone and then back it off. Perhaps I should back it out a bit more. The lever does have free play and the action feels fine.

I had to replace the springs in my 69 lightning after it started to slip some even after new clutch, and plates. If I read the book right a free spring is suppose to be 1-13/16" long. The springs are easy to get, and aren't that expensive. Good luck!

Worn cush drive rubbers, spider and end plates allow the clutch to tilt under load.
Polished and warped plain plates.
Combimation of the above.

I did not check the springs. I'll pull them and measure the length. Thanks

When I looked at my clutch spring screws, they were not very even. two of them had much more thread showing that the third one. I pulled the springs out and they measured 1 13/16 inches long as the book said. I put the whole thing back together and again, I need to have two of the screws tighter than the third to get everything to even when I engage the clutch. I am guessing that one of the springs must be weak in some way. I tried adjusting the screws to different points, riding the bike after each adjustment. I was amazed at how sensitive those little buggers are, but everything seems to be fine now. Thanks for the advice. Doc
