Sammy Posted March 21, 2009 Report Posted March 21, 2009 (edited) A little run down of the quad. 98 banshee, mods include .020 over fresh cylinders and bottom end, V-Force 3's, Moose boost bottle, K&N 2into1 pod and Paul Turner mids w/ fatboy silencers, stock box with lid/snorkel. I actually purchased it last night, overall I am very pleased with the performance of it. Now for the problem, i got it home last night, it was about 55 degrees outside and it rode great. It had excellent throttle response, and great pull in the band. I couldn't really stretch it out b/c it was 11:30 at night and the headlight wouldn't work. So this evening after work ( 42 degrees) I decided to poke around with it a little, I converted the 2into1 pod to an open element system (No air box), drained the fuel and put in some fresh leaded 111 mixed 52:1 with golden spectro. Well I kicked it off and it was bogging real bad and idled like crap when it was dead cold. A couple of backfires, and no power at all past about 35% throttle. Obviously its sounds like it leaned out quite a bit. I don't have a clue what size pilot's/mains are in it or even where the clip is set. So my question to you all is where should I start with the jetting pilot/main sizes? It also appears that the carb's are out of sync a little, the left one moves before the right one. The right side doesn't start to open until about 10-15% throttle. Edited March 21, 2009 by Sammy Quote
Sammy Posted March 21, 2009 Author Report Posted March 21, 2009 I found a set-up in the jet thread a little further down, guy is running pretty much the same setup as me. accept he is at sea level. He's running 320 mains and 50 pilots. Once I calculate that down to my elevation would that be a good starting point? Quote

Once I calculate that down to my elevation would that be a good starting point? 50 pilots are huge for a stock carb. you'll probably be fine with the 25, but maybe 27.5. 310-320 sounds close for the main, but you'll have to play with the needle and air screw to get it right in the low-mid. if it's the stock head, try putting some 93 octane, or 50/50. the 111 isn't really doing anything without compression and timing mods. and sync your carbs. tremendous improvement in the low-mid, not to mention idle.

Sammy Posted March 21, 2009 Author Report Posted March 21, 2009 Alright I got some 310's and 320's I'll try those tonight. On the clip which way is more lean and which way is more rich? Also the idle air mixture screws clockwise is richer right? I was watching the sync video on you tube, but my carb's aren't setup like that. They don't have the adjustment screw on the side. There is a large adjustment on the back of the carb's facing towards the air filter. Its about the size of a nickel with a flat blade slot in it. Is this the sync screws? Also my left carb is open more at idle than my right, is that correct? Quote
Sammy Posted March 22, 2009 Author Report Posted March 22, 2009 The 320's seem to do the trick quite well!!! Man this thing is awesome. I'm super stoked right now. :thumbsup: I still have a little tuning to do on the pilot and I need to remove my TORS. But shee feels great. Quote
