Wondering if anyone out there is running these carbs. I am looking for a known good starting point for main jets. Long story short, I am running these on my RZ 350 road race bike that I have recently converted to Banshee cylinders (BTW I have some powervalve jugs for sale, with cool head) I had ignition problems before and jetted from 320 down to 240 (yikes) and I know that is too lean, so said the piston. My cylinders are ported and 4mm stroke, I am running high rpm and approx 75+ hp. I am inclined to go with 310 to start, any help would be miles for me!!!
