My Banshee (optional)

Found 3 results

  1. Not specifically for a banshee but I figured I’d ask here anyways since banshee guys tend to know answers tuning questions. I have a PWM 38 4XL from a 1997 YZ250 with a needle that I can’t seem to find any information on. Most likely due to my lack of hands on use of Keihin carbs. The bike has a built engine with an old generation bills pipe that I have no actual paperwork on so the carb may have some wild needle in it that’s not normal for a PWM. The needle code reads N40G from what I can tell. Any info is appreciated.
  2. Looking for someone to clear the confusion on aftermarket banshee needles. My current build has stock needles and has a dead spot off idle. I tried various pilot sizes and settings along with needle clip adjustments and main sizes and I still cannot fully solve it. Engine passed leak test so its not a lean condition. I tried a set of Toomey needles out of my buddy's bike and they cleared the issue immediately. Bike pulls hard right off of idle and makes power everywhere in the rpm range. If I have to pay the $50 for the Toomey needles off their site I will, but I'd like an explanation on the difference between all of the companies that make needles for banshees. 1. What are the major differences between them all? (Dynojet, Moose, FMF, Toomey, Vitos, and the ones from FAST) One of the banshee guys local to me told me they are all the same Dynojet-based needle and are just rebranded. This looks like it may be accurate as the Toomey, FMF, and Dynojet needles all look the same with the machine cut tip and 6 clip positions. 2. Due to how expensive needles are, I've considered the needles from FAST but I'm curious if they are the same needle as the toomeys but with one less clip position. Any information on these specifically will be greatly appreciated.
  3. So, I sold my stock carb set-up in favor of the 33mm PWK's for my future Serval build. What jets and needles do you recommend with the following mods: 33mm Keihin PWK's w/K&N's and Outerwears UPP Intakes w/cross-over tube VF4's Mull Pump Gas Head +4* timing 91 octane w/YamaLube 2R mixed 40:1 stock pistons stock port CPI pipes Sea level in Pismo 75-80* F What pilot? What needle? What main? Stock 33mm PWK's come with the following: 52 pilots CGL needle 165 main jet I talked to a shop and they mentioned the following to start: 48-50 pilots CGL or CEL needles 155 mains Thoughts?
