big bore jetting

[64xracer]

I am getting ready to do some work on my shee, and I was wondering, what size of mains to start out with, on a banshee that is 70mm bore, stock stroke, ported, with Keihin 34 pj carbs and twin K&N clamp ons. I am going to be running T-5's when I get it all back together. Elevation is 1600. Thanks

I'd start w/ a 175 main, needle halfway, and a 58 pilot. This is just a baseline, but should get you close if not a little rich..

I run a keihin 35mm 2 into 1 carb setup.

Trinity mx ported.

420cc which is 70mm.

Trinity turbo head mod+shaved head.

vforce 2 reeds.

I run the motofast 2-1 pipe right now, come a month or 2 from now when the lake freezes I'll goto my T-5s. When I have my T-5s in I run a 52 pilots and a 215 main with the needle on the 4th clip and 2 turns out on the air screw.

Your running a 2 into 1 setup, he has dual carbs...

This is true.
