I know you mention rejetting the carbs. Check out Wright's Motorcycle in SLC. It's about 3500 S. State, right next to Harbor Freight.
It's a one stop shop having a motorcycle store directly next to Harbor Freight.
Anyway, I got jets for $3 each there I believe. the guys were super helpful about how many sizes to jump up based on the filters I got. I haven't got to try it yet, so we'll see. Even if it's wrong, I'll just go back for more jets.
Stoked to see photos of this thing when it's done. Tomorrow is going to be gorgeous here in SLC. First day over 50 degrees since November or so. Wish my bike was ready to ride!
