I always have a ‘Racer pattern’ Gear-change (1-up~4/5-down) on my Bikes, where possible.
On most Bikes it’s simply a case of flipping the Gearbox lever over, or fitting a Lever ‘rearwards’ on the Shaft, but obviously that’s not an option on Guzzis.
Had to do a bit more work . . .
Pivot fitting is an old Handlebar clamp top-half, machined down a little (width and height), with a machined pivot-piece bolted to it. Fitted two 6mm Rivnuts into the Frame for the mounting.
Bell-crank is made from 3/16" Alloy Plate, and has a Delrin Bush bonded into it.
Upper Link Rod is made from two cut-down Female Rod-ends, joined with a short length of Studding.
Lower one uses the original lower fitting, joined to the other Rod-end with 6mm Studding.
Also had to trim a little off the Starter Motor Cover for clearance.
Â Will take more detailed pics of the parts soon (if anyone’s interested).
It works OK, but I want to flip the Bell-crank over, and make a longer lower link, to get the angles correct.
