How accurate do you want to be? It was 2 or 2.5 I think (a long while since I did it).

When I did mine I measured the idle ignition before/after and saw a nominal 2deg shift, but you might be able to get it a touch more depending on how far you want to shift the pick-up. As per the photo the pick-up body sits in a recess in the cover, you could fettle some of the cover away to move it a little further, the slot would probably break out of the end of the tab so a slightly larger dia washer or even a stepped item made to clamp it if the tab ends get too near the bolt centreline (if you see what I mean).

Hi All

OK I'm having a small batch of 15 keys made at the moment, due to the small qty it will be a couple of weeks before they arrive with me.

See the For Sale section for more details

Some nice info on here about what the advance key helped with

Look at the bottom end torque after the key was fitted

and after the bike was jetted correctly which IMHO would have been most of the gain.
