Not sure how long those extensions are but I recently had trouble the the handbrake jamming at about 3 clicks up and not doing anything. I could not see the problem so just changed everything, levers, cable the lot. It now works but I have a problem with the LH cable being tight on the exhaust where it rises over the axle. I know this is partly due to the 'new' tubular manifold I fitted being 2" shorter than the old one so I had to move the rear section forward (although I don't remember having this problem before changing the cable), but longer levers might have the same effect.
(Anyone able to suggest where I can get 6" of 2 1/8" bore pipe to extend the joint on the exhaust)?
