Just got around to cleaning and rejetting after installing my Dyna muffler. Ordered a pilot jet and 2 larger main jets from Jets R Us, and they came in a couple days ago. Pilot jet was fine, changed it out no problem. After tuning the low end/idle mix and doing the white spacer mod, I went to change out the main jet today because it was way too lean and the jets are different from my stock main jet (see pics below):
The top is the new "main" (right) vs the stock main (left)
The bottome is the new "main" (left) vs the stock pilot air jet (right)
The O.D. of the new jets seems way off at the head, but they thread into the main jet opening with no problem, and the ID/opening looks correct compared to the stock main jet.
Am I crazy in thinking that they drilled the right size (147.5, 150) opening in the wrong jet? These are supposed to be genuine jets...?
Anyone have any ideas? Should I try to run these in place of the stock? This is the first time I've rejetted the bike so I have no idea if this is normal...
