Can anyone recommend an after-market clutch lever for an 1985 K100?

I have a custom K, but the current after-market lever doesn’t connect well to the bmw clutch cable.

The current after-market doesn’t receive the bmw clutch cable well and hence setting the clutch cable to K100 specs is nearly impossible - looking for a suggestion for an after-market clutch lever that works better.

Venhill do a clutch cable kit that includes a range of different sized nipples. You's be able to choose one that fits your aftermarket lever fine. The other advantage is that you could make the outer to the ideal length for your bike - essential for the lightest possible operation.
