Slinger what I would do is set up a timing light, and mark the timing advance from idle to wot at 100 rpm increments. transfer those marks to degrees using a degree wheel. Snap on has an inductive timing light w/ a built in tach. That will give you the timing map of your cdi. you can add timing btdc to increase the power, or retard the timing if you feel that range is too close to detonation. I went lower than stock all the way to 7000 rpm,s and then went 3 degrees over stock to the top (2 degrees over at 11'000-13'000). The best you can do is guess, run good fuel, and hope! let Suitai see the map you make, anä let them know the areas you want to improve. My GUESS for a 4t would bee +2 till 2500/+3 till 6'000/+2 till unlimited
...i gotta research this further....
