I know I should look at wot, but I have to keep it away from wot for 500 miles in order to properly break in this clutch. I might have to change these jets later but for know I can't drive it this rich.



Sorry as I did not realize you have to keep it from WOT for a bit. Then do what works best for you now. Course you may have to change the main jets later if you tune for WOT. I was also curious if you have both a primary and secondary power valve since jetting was 80 on all 4 corners ? I would guess it does have both power valves or someone has been in the carb before ?
