figuare9 Posted June 18, 2011 Report Share Posted June 18, 2011 (edited) 4 mill, ported for Gold Series SST pipes. Cool head Stock carbs 1450 ft elevation 60-80 degrees Need to rebuild carbs. Need main and needle jet size. Stock airbox. (Pre filter screen on filter) Also, I noticed that my banshee leaks fuel when it's not running. Float setting? or maybe the new needle will fix that? It also comes out pretty fast when it's running while on two wheels, or while driving on a steep angle. I was going to post this in exhaust/jetting, but I figured it'd be more appropriate here due to the fact that i'm having an issue with my carbs as well. Move if necessary. TY.

I had to replace my float needles and seats to stop my fuel leak when not running. mine to this day leaks when on 2 wheels or during sharp hill climbs. Hope this helped. Call Jeff over at FAST and he will be able to put you right in the vicinity of where you should be with the jets he has helped me within only having to adjust my air screw.

Alright, I haven't started this thing yet, because I'm waiting on my reeds to get here. but I have the carbs in front of me here and I'm stumped.. I just installed a carb rebuild kit, and went back to a stock needle. the ones that I replaced were just a little bit longer. They didn't say a size on them, but I know they were different. So... From here I ask... I'm running stock jet needle, 310 mains, 32.5 Pilot, and a 345? needle jet. Think this would be a good starting point?

Larry's Shee Posted July 10, 2011 Report Share Posted July 10, 2011 What carbs are you using? Quote Link to comment Share on other sites More sharing options...
figuare9 Posted July 10, 2011 Author Report Share Posted July 10, 2011 Stock, I mentioned it in my first post. Learn to read? kiddin. I duno, I won't be starting it until tomorrow, but I wanted to get a good idea where to start while I have the carbs off the bike. Quote Link to comment Share on other sites More sharing options...

figuare9 Posted July 10, 2011 Author Report Share Posted July 10, 2011 stock needle 4th clip from the top 2nd from the bottom 30 pilot and maybe richer on the main When you say "top" and "Bottom" Do you mean the blunt end by top? and the pointed end of the needle as "bottom"? I know, dumb question but I gotta make sure How much richer on the main? I only have 300, 310, and 320's. My banshee ran like a beast before I did the 4mill. It was absolutely 100% stock before and the guy that had it before me installed the full fmf Gold Series SST pipes. He jetted it to the 300's, 32.5 It ran really well before. Seemed a little on the rich side, but it pulled your arms off and never fouled a plug so I never messed with it. Since then, I'll have the 4 mill, +4 timing, ported for the pipes and Vforce 3 reeds. So.. I went from a decently tuned setup and changed it from whatever needles were in it before to stock (the needles I replaced were a little longer), and jumped the 300's to 310s. However, I will definitely try what you said, and run the clip one closer to the "Pointed" side of the jet needle, as right now I have it clipped in the middle.

Larry's Shee Posted July 11, 2011 Report Share Posted July 11, 2011 I'm sofa king we todd did and blind too I'm running simular but slightly less set-up, 310, 27.5, stock needle middle clip, 1 1/2 turns, 1000 ft I'd start 320, changing jets is easier than pistons. As to you're pilots not many run much more than 27.5s. Quote Link to comment Share on other sites More sharing options...

As to you're pilots not many run much more than 27.5s. See... That's why I made this thread. My shee ran wild.. It was litereally neck and neck with a 450 with just the exhaust. But it had some weird jetting. I know most people are saying 27.5 is about average, but I was just a little bit rich before with the setup that I had. I kinda liked it. Its always safer to be a little rich, and I never fouled one plug out in over a year. I'll run this in a way that's easier to read. BEFORE PORTING & MODS (Only has exhaust) -300 Main Jet -32.5 Pilot -Aftermarket Needle jet (slightly longer in size) -2 turns exactly out [Ran almost perfect. Slightly Rich] After Upgrade | 4 mill crank | Porting to SST exhaust | Chariot Cool Head | +4 Timing | Vforce 3 Reeds | -310 Main Jet -32.5 Pilot -Stock Needle (Middle Clip) -2 turns out..Still. Have yet to start the motor. Will tomorrow when my reeds come in. Hoping I can get a really good idea of where to start the jetting while it's still apart. So far, from what I've gotten out of this thread so far is that I'm going to want to start with my 320's. And adjust from there. I'd like to hear a few more opinions about the pilot though. If my shee ran great with a 32.5 why are people running 27.5? And if it ran good before should I change it for the new mods?

Jereme6655 Posted July 11, 2011 Report Share Posted July 11, 2011 well.....you can always throw in the 32.5 and see what happens. does it bog a little bit? sluggish off of idle? my bike wouldnt run on one cylinder (previous owner had stock 25 pilot on with FMF Fatties) I dropped in a 27.5 and it woke it up like no other. Then in the great quest for more power and a g-force induced grin.....i had it ported. Really powerful now.....but it got real sluggish on the off idle pull. so i dropped in a 30 and adjusted my idle screws and it woke up again....
