Junkman said:"If the pressures are too [...] high you'll have to lift off the throttle to prompt the upshifts, and you'll get a "clonk" on the 2-1 downshift when coming to rest on a closed throttle."
I have exactly this effect with the 'new' gearbox, courtesy of fylde69 (many, many thanks again!).
So does the cable need to be slackened, or tightened, to lower the pressure, and by what amount to start with?
Junkman said:My inner cable has a collar about half an inch down, so if I move the outer casing up, it will pull the inner cable further out of the gearbox.
I did adjust it down, to the extend, that I could feel the inner cable being pulled against a mechanical stop, concluding this means the valve is fully closed.
I then adjusted the outer cable as far up, so that there is no gap between its upper end and the collar around the inner cable.
Anyway, the behaviour didn't change at all.
