banshe98 Posted March 21, 2004 Report Share Posted March 21, 2004 I have a 98 banshee with FMF fatties and powercore II silencers, pro-flow intake no lid. aftermarket head. reeds and spacers and I think the cylinders are also bored. I am running 300 mains, 27.5 pilots and the needle is in the stock position. It seems about perfect with this jetting, but has a little off idle bog. I am just wondering which way I need to move the needle to fine tune it. thanks Quote Link to comment Share on other sites More sharing options...
Banchetta Posted March 21, 2004 Report Share Posted March 21, 2004 Try raising the needles one notch by lowering the clip to the 4th slot from the blunt end.... Quote Link to comment Share on other sites More sharing options...
sredish Posted March 22, 2004 Report Share Posted March 22, 2004 Absolutely. Fatties love the 4th clip on the needle. One clip on the needle is usually equal to a half size when transitioning into the main. That should be fine unless your a little fat to begin with.

Otis Posted March 22, 2004 Report Share Posted March 22, 2004 rasing the needle richens the mix? Quote Link to comment Share on other sites More sharing options...
BansheeBrian Posted March 22, 2004 Report Share Posted March 22, 2004 You bet! Lowering leans. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted March 25, 2004 Report Share Posted March 25, 2004 My fatties always liked to be leaner on the mid. 1 down on the needle for me with stock carbs. Quote Link to comment Share on other sites More sharing options...
Ducman Posted March 26, 2004 Report Share Posted March 26, 2004 If your bog is just "off idle" I'd say try tuneing your air screws. Make sure shees warm, turn them in 1/2 turn and see if it gets any better, try another 1/2 turn in see if it gets better yet ( or keeps getting worse) and figure out what setting works best. The air screws are easy and take no time to adjust so try them first. If they dont solve your problem or the bog is a bit higher in the throttle position than "just off idle" then try going 1 clip richer on the needle.
