Hi Staggers,
No, I haven't been playing with clutches yet, I'm still knee deep in painting. While I've done some automotive painting before, it was years ago and I'm certainly learning as I go (read lots of mistakes, but hopefully I'll cover them up ok!). This whole rebuild is meant to be a learning experience otherwise I'd just farm the whole thing out to a shop to do.
Getting the slave and master from the same bike is a good idea as they should match up to provide a good combination (depending on the clutch pushrod movement requirements of the original bike).
The slave I have is (from what I can measure) a 30mm diameter cylinder and the master is a 13mm so that should produce a 4:1 ratio between the two, based on area. So, 4mm of master cylinder movement should be 1 mm at the slave. I'm looking for about 2 - 2.2mm at the clutch pushrod, so that would be about 8 -8.8mm movement at the master cylinder. The master seems to have a full stroke of length of about 15mm so that should be plenty. I may even have to build a lever stop to prevent too much pushrod movement.
Do you guys want to see in progress painting pics or wait for the final reveal?
