for running a straight pipe what jets would you suggest?
is there a jetting guide around here somewhere?
the cheapest performance mod is going on a diet!

Try a 30 pilot and a 130 main.
See how it does.

Since all jetting varies with temperatures and altitude, as well as what mods are on the bike, you have to try a starting point, and work it in from there.
Better to start a little rich, than to burn a piston or seize the engine.
Home of the ACE Fireball 535 Bullet,  Ace GP Hi-Lift Roller Rocker Head Conversion. Pistons, cams, etc. Highest performance Bullet engine mods available anywhere.  AVL mods available. UCE kit coming.

Ace is right, but a straight pipe may not be a great idea except to be loud. BTW Scooter Bob tried a straignt pipe on one of our UCE/EFI bikes yesterday and the EFI kept up with it. We have been surprised at the flexability of the system.
