Hi Tom, give Nick Prionas a try at 2t racelab, e mail, tonelessdiy@yahoo.gr . He is in Greece, but dont let that put you off, Nick is a top man and very reasonable on prices. You can look him up on twostrokeracelab, he also has an ad on a certain auction site under nsr250 for repairing pgm's, i have used Nick myself for various things, and he is so enthusiastic about 2 strokes.
