Power valves

#1 Post by Jarrettvp » Fri Dec 09, 2016 8:11 pm

Hi. I'm after a new / second hand power valve for one of the rear cylinders (2). Anyone got any ideas?

Thanks in advance.

I have bought a set of these and they are of good quality.
The only thing I noticed was the the relationship of the coupling flats was slightly different to stock (a couple of degrees at most). I am using a Zeeltronic, so can adjust the opening and closing positions easily. With a stock PV controller, adjusting the optimum opening and closing positions using the cables alone may be tricky.
