Hi Guys, I'm after some help.

Ive just completed (well almost) an upgrade on my MC21. New pipes, reeds, rejetted, new heads, suspension etc. My problem is now that the power valves won't work.

My old PGMIII burnt out pre-upgrade and I had it repaired and tested by 2strokeracelab and returned to me. While it was away being repaired I cleaned the powervalves (which were very coked up), which now turn with ease. Popped the cables back on and turned the servo by hand to ensure the servo also turned.

Got the PGM back and put it into my new ish looking bike. The bike runs, but no action on the powervalves. I rode it with the valves manually closed, then open. When closed it wouldn't rev up (as expected) and when open it went nuts at 8000rpm. So no other running issues that I could see.

So the PGMIII is good (I think), so is there must be something else preventing the operation. Can anyone help me with this?

I've searched the forum but most issues come down to the PGM, which I believe is fine. This is the only thing stopping me from getting on the race track!
