I had a problem with the clutch not working, it simply did not free upp when I pulled in the handle. Turned out to be that the supplier of parts had sent my the wrong rollers for the clutch basket, I think 1/4 X 5/16 instead of 1/4 X 1/4 (but I may remember the numbers wrong). Once the correct rollers were fitted it worked just fine. I have the single spring clutch.
Yes Simon they should be 1/4 x 1/4. Not as simple with Triumph's though! Suppliers will often send you 1/4 x 1/4, when in fact the Triumph rollers are about 12 thou (.012") shorter in length. This caused me a lot of problems many years ago with my first Triumph. Ron
