My dyno experiance so far with my 790 America;
1 TOR pipes, Unifilter, AI removed, 135 Main = 46 Hp running fat
2 TOR pipes, Unifilter, AI removed, snorkel removed, 135 Main = 52, still not good on mixture.
3 TOR pipes, Unifilter, AI removed, all snorkels removed + enlarge opening to filter diameter, 135 Mains = 55,5 hp
4 Thunderbikes pipes, Unifilter, AI removed alla snorkels removed + enlarge opening to filter diameter, 145 Mains = 65 hp and 65 Nm torque and a little bit lean on WOT. Changed mains to 155 which works well.
5 I have now changed to CRII carbs, feels much stronger & quicker but not yet tested. Hoping to break into the seventies.....
