airstriker starting point

[bansheecaptain]

getting a FAST dune/play 4mil port . +6 timing 20cc domes . and rocket pipes. i have a set of keihen 35 pwk air strikers . and ive done some reading on here and usally the form get highjacked on how they like the carbs . but what i found is they like to run alittle smaller of jets. also i ride at 2000ft . so would 150 main 50pilot and needle in middle bea good starting point?

Sounds like a good start but what needle are you using? Im about to go with a CEL and see how it does. Seems to be a popular needle for these

[RadarRacing]

Many of the airstrykers have needles in them that are far off from whats needed. I used CEL needles in mine leaned out one notch from the middle, 45/48 pilots and jetting in the 148-155 range. Had them on two different motors. I think a 50 would be a little bit rich on the bottom cuz thats where the airstrykers are designed to be a little bit more efficient at sucking fuel with those little angled wings. I would start with a 45 pilot.

I had the same set up , i ran 38p is the best you would never have to change from there , cel needle in the middle , and a 152 main , 1.5 turns on the air fuel. 45 or 48 pilot is way too rich airstriker like the lean pilot thats the key to tunning them . Tune the bottom first , then do a plug chop for the top end

Seems like you already understand the car the carachteristics of those carbs. The base lines you have been given should suffice. Start it up and keep checking the plugs.

F.A.S.T. sells them or wildcard racing.

Precision Powersports , Wildcard , FAST , No Limit Powersports will all probably have them in stock. If you dont get the bottom leaned out it wont launch like you'd want. They will bog off the bottom.
