The 'Hunter Engineering' knee grip rubbers have good definition, fit the backing plates well and are the ones I've always chosen to buy to date....
I must admit though, I've never bought two pairs at the same price and they are now an expensive, maybe over expensive product for what is involved...Ian
All other rubber parts aside, I used a short length of reinforced rubber hose with an ID appropriate to the OD of the kick start lever. Bought it a the local hardware store. Soak the hose in hot water, and it slips on easily. Mine is still working OK after 5 years. I'm not one for restoration perfection, so this works fine for me.
