did some tuning stuff this weekend and popped the cap off my carb and pulled my jetting config. this is what I'm currently running:

(prim/sec)
Idles: 75/65
Mains: 155/150
Airs: 180/175
Screw: 2 turns, little +

this is with the Offy Dual Plane manifold and a K&N round air filter. I just put that "old" filter on while I was waiting for my Ramflo filter to dry. the Ramflo is a foam filter. I think it's the highest flowing air filter you can run. I noticed that it seemed a little sluggish when I put on the K&N; my A/F meter was showing that it was actually running a little bit lean, which really doesn't make sense to me. I'd think, less air, run rich, right? unless, of course, the K&N flows more air. don't know.

anyway, it had 150/150 mains in before the filter swap. AND, I'm considering trying the stock air cleaner assy which should choke it out a good bit, so I'll probably have to rejet again. the reason I like the stock air cleaner assy is that it pulls air in from the front of the vehicle; cooler air, that is. that's what I hate about the Weber setup; I'm just sucking in hot engine bay air. was toying around with the idea of a functional hood scoop or some quasi snorkel thing, but eh.

anyway, food for thought.
guess I'm officially back to Weber tinkering smile
