Re: Anyone using an adjustable clutch push rod?
Beats me ... I didn't know anything had a 7/8 clutch MC. But if it looks like it will fit, it probably will. Just don't blame me if your left thigh winds up bigger than your right !
The ratio of force (and distance) goes with the square of the piston diameters. So changing from a .70" to a .875 (7/8") will result in a 56% increase in pedal force (and 56% more travel at the slave, which might be a problem in itself).
If you meant 5/8 instead of 7/8; I think that would be a bad idea. The problem is that the slave travel goes down at the same time as the pedal force goes down, and the slave travel on a TR6 is already marginal with the .70" MC (which is why many people switch to the earlier .75" MC).
