sweetshee4312 Posted February 27, 2004 Report Posted February 27, 2004 hey guys i just got a set of mym fattys, its around 30-50 degrees around here now, and im just putting em on, there new, im around 800-1000 ft above sea level, i was gonna get at 27.5 P's-- 280 M's and 3rd needle position, but i dont have the pilots as of right now, i have stock do u think it well be ok for like a weekend or should i not risk it, i mean cause i know it well be lean Quote
Banchetta Posted February 27, 2004 Report Posted February 27, 2004 Keep the stock pilots in there for now, run the 280's w/ the lid on and snorkel removed, raise the needles to the 4th clip from the blunt end.....If you get some 290-300 mains, then you can run w/o the lid or modify it... Quote
sweetshee4312 Posted February 27, 2004 Author Report Posted February 27, 2004 well i have holes in my lid, but aklos, there is a guy around here with the same exact set up as me, running 280s with 27.5 Ps and he said it perfact, and i was woundering down the needle is richer and up is leaner right Quote
Lepew Posted February 27, 2004 Report Posted February 27, 2004 down the needle is richer and up is leaner right Putting the clip towards the point is richer, putting the clip towards the blunt end is leaner. Quote
Banchetta Posted February 27, 2004 Report Posted February 27, 2004 Its hard to just put in jets according to someone else, they could still be off and different areas will also affect jetting..these are only baselines and you still have to fine tune it... Quote
sweetshee4312 Posted February 27, 2004 Author Report Posted February 27, 2004 should i start rich and work down like start at 290 and see how it works, then go to 280s, an dim woundering do i have to take out my carbs to jet, or can u just like turn them kinda sideways, casue i rejeted before and i had trouble getting them back in, as well as getting them out Quote
Ducman Posted February 27, 2004 Report Posted February 27, 2004 See my settings for Gnarlies in the signature. That's what runs perfect for me, results in a text book plug chop for 500' elev 40-60 degrees. They jet the same as Fatties. When I bought my pipes the jet kit and instructions from FMF said to use #30 pilots and 260 mains with the lid on snorkel removed and the directions that came with the pipes were for Fatties. Thats for 60 to 80 degrees, sea level. If you can get it to idle with the stock pilots the 280's will probably be about right with the lid on at your elev. and temp if you are running a foam filter or stock filter. Same conditions with the #27.5 or 30 pilots then 270's would be good on the mains with the lid on. The needle doesn't make a real big difference on mine from stock clip to 1 clip richer probably due to the larger #30 pilot. Seems a little snappier going into the band at the stock clip position.
