I sent you a PM. I am the one who had the keys made specifically for the Polaris twins, 600, 700, and 800. I had 0.040" keys (5 degrees advance) and 0.050" keys (6 degrees advance). I had 25 of each made and I just sold out. I will have a few more by the end of the week as I just ordered more from the machine shop.

All other keys online have to be ground to make them fit. The ones I had made fit perfectly on the Polaris twins with no grinding required. Mine also cost about 1/2 of what the others cost.

Anyway, advancing the timing on the twins does improve performance some and it is a cheap mod.

Please PM me if you are interested.

Generally, the more the timing is advanced, the better performance and fuel economy you will experience. Advancing the timing makes for an earlier spark, which allows for a more complete fuel burn.

Caution must be taken when advancing the timing. Timing that is too far advanced can result in preignition (pinging), which isn't good for the engine. Basically, you want the most timing advance short of pinging.

When I was tuning Harley Davidsons, I advanced the timing until the point where the engine would ping under a slight load, then retarded it one degree from there.

Good luck!

With these keys no-one has experienced any of the pinging.
