jimp1967 Posted February 28, 2010 Report Posted February 28, 2010 I just bought a '99 Banshee and could use some advice. It has a Cool head,pro design intakes,boost bottle,still has tors,T-5 pipes,26 mm carbs,K&N 2 in to 1 filter with lid and snorkle.It has 122 compression on right and 124 on left. The bike runs strong on 3/4 to full throttle but boggy down low. It is leaking fuel out of the over flow tubes and the plugs stay wet. Now I pulled the carbs and this is what I found: 220 mains, 25 pilot, clip in 4th slot from flat end of needle. I live in Texas (Houston) hot and humid most of the time. Right now it's around 60 to 65 deg temps at sea level. I have read and done searches here on the site and this is what I think I should start out with for a ballpark tune: Tors delete, delete boost bottle,remove air box lid, 290 or 300 mains, 27.5 pilots,clip in middle position, air screws 1 1/2 off the seat, new needle and seats and sync the carbs. Thanks for any advice! Jimmy Quote

Thanks for any advice! Jimmy Sounds to me like you are going in the right direction, i would start with the 300 maybe 310. Quote

Also what ratio should I run the pre-mix at? I will be running 93 octane and trail riding with some straights thrown in. Thanks. Jimmy Quote

If that's a good change then what size filters? And would the 300 main still be good to start with or should I go with the 310 first? Thanks Jimmy Quote

Just run good outerwears, you will need to run 320 or 330 with them. I mix at 40-1 alot of guys like 32-1 Quote
