All I can offer is more specs on my bike:
03 TBA 790
Bubs slash cuts
UNI, no snorkle
45 pilots, stock needles, 1 shim, 135 mains
Wrong HD type thunbscrews (set too rich?)

I think I can fix my rich at idle condition by changing
the thumbscrews to Brent's new correctly tapered ones,
and re-adjusting/balancing the carbs.

Anyway, this dyno experience confirmed my seat of the pants
feeling that my bike pulls pretty good. It doesn't get good
mpg, but if I wanted fuel economy, I'd be riding a moped!
