Clutch enquiry

Postby raeburn » Wed Dec 16, 2015 9:04 am

Hello, I am looking to buy a R100 hopefully and was wondering how heavy the clutch is, suffering with tennis elbow at the moment!
Thanks Phil

Should all be fairly light but '81 is lighter than the earlier ones

There's an interesting device here, http://www.benchmarkworks.com/articles/ ... lutch.html but I don't know whether it would suit an R100.

Hi
a good quality cable properly run reduces the effort but mine was never light until I explained my problem to Noel Fletcher at Fourways who made me a modified set up using a scooter brake cable.

I should have asked him what he did cos it gave instant improvement, almost 2 finger effort. He assured me that if ever it broke an original just would go straight back in, but that would require normal weight.

Use a spring balance to test the effort if the seller lets you. Try the number of repetition pulls you can manage before your arm stops working. From memory, years ago, it was about 30 pulls on the original cable, no limit with the new set up. If you are near me you can try mine. I dont know if you are which is the reason I ask people to put their location in their profile.

If I remember rightly the benchmarkworks adaption works on bikes until 1981.

It does require chopping the nipple off a clutch cable which is then secured in a brass fitting by Grub Screws, I dont think that its very secure. Doesn't work with Venhill cables because the inner is too big a diameter. Various drawings out there of systems that retain the cable complete.
