clutch perch and lever idea needed
Posted Today, 05:17 PM
I am using as many of the BMW components as possible on the running and as many standard dirtbike parts where possible so I can make any needed repairs while out on an adventure in the NEAR future. Handlebar controls are a tough spot though. I HATE the stock BMW bar controls and switches. That made me want to change them out to a more dual sport style set up. That brings me to the clutch.
The BMW uses a diaphram clutch with a single center disc, similar to most manual cars instead of a basket and multiple discs. The clutch throw on a BMW is longer than most other bikes. The pull is not hard at all, just a bit longer. They do this by a larger distance between the pivot bolt of the lever and the cable end.
I tried using a universal Moose racing perch and lever but could not get enough throw. The cable end on the BMW is also 10mm where most other bikes are 8mm ends.
Does anyone know of bikes, older or newer, that use a longer throw and longer distance between the pivot and the cable end?
The BMW has a distance of about 1-3/8" from the center of the pivot bolt to the center of the hole for the cable end. Most bikes use a distance of about 1-1/16" which is less throw with the same lever movement.
I do have some pics if anyone is interested in seeing the beast, it is not beautiful, but should be a cool and different adventure bike when done.
