I have found a nice bit of highway where i can do some plug chops
And i have access to an AFM measuring device, i was just looking for some first hand info on a safe starting point.

Judging by your comments Dave, you think going leaner than a 145 main is a bad idea ?

I had some trouble looking for a mechanic as well, as they guy I had planned to use moved down to Sydney. After a while I heard about a guy over in Springwood, Tony Bogaart. He's doing the tuning on mine as we speak, and has previously done a bit of work on some friends' nsrs with good feedback. When I dropped my bike off he had a custom framed race bike powered by an rz500 motor up on the dyno, and he seems to like the two strokes.

If tuning it yourself doesn't work out I can give you his contact info.
