Just Got A Banshee, Help With Jetting

[J.D. Blackwell]

Just picked up an clean '02 last night. It already has a set of Pro Circiuts on it. Still has the dang ol stock air box & filter. Going to get rid of it and get a pair of "clamp on" K&N's. What size mains and pilots do I need to get for it? The previous owner has been running 16:1 premix. I am going to at least 32:1, but maybe 40:1.

 

 

Thanks for any help,

Justin

I'd go up 4 or 5 sizes on the mains for the K&N's, but back off a size for the change in premix ratio (16:1 is leaner than 32:1, from an air/fuel standpoint)...or if you're close to sea level with the 2 K&N's, 32:1 premix, and average temps (60-80F), I'd start with 320 or 330 mains, 30 pilots, airscrews 1.5 turns out and needles in the stock (middle) clip position. Good luck.

yeah, I don't know what jets are in it now. I believe my altitude is 400' above sea level.

 

 

I appreciate the info.

 

 

P.S. If I buy a K&N jet kit, what size mains and pilots do I get in the kit?

I agree w/ Benn and go w/ his jetting setup to start and go from there. You should just order some jets, cost less money then buying the jet kit that doesn't have much to offer and probably the wrong sizes...
