Hi Guys,

I'm having some big electrical issues with my NSR going back on the road again. I ran the bike and it burnt the PGM III unit while riding really badly as I could smell the burnt wiring inside the box from outside the bike.

When troubleshooting I noticed that the powervalve servo didn't do its on/off thingy when turning on the bike, i.e. it didn't move on/off along the cables making that short noise from the servo everytime you start the bike.

If the servo isn't working or the powervalves are stuck will this cause an overload in the circuit frying the PGM?

That sound like a pgm burn out , The most likley cause is sticky powervalves . There is a post on here about repairing them http://nsr250.net/forums/viewtopic.php?t=9496 . Check you powervalves to see if they have full movement and that the cables are free . I cleen powervalves and lube cables regulary to prevent that from hapening

Jammed powervalves are an absolute certain way of killing your PGM. You may be lucky and have only fried the transistors, though I have seen cases where the board was melted too. Fingers crossed!
