Now on the lift, '95 Husaberg FE501e. Many 'opportunities' here. These early bikes had very aggressive cam ramps which put a lot of force on the entire valve train. Couple that with weak oem cam chains, poorly designed chain slipper and an alu cam sprocket and there's trouble.

I won't even go into the issues with the Dellorto VHSB 38. Information and parts for the early bikes ('89-'96) is challenging as well.
But she's slowly coming around
