I just bought a Air stryker 38mm carb for my 250r I have it ported fmf pipe, Boysen rad valve. I know no one can tell me the exact size of jetting but can someone tell me ware to start. I have a 172 in it right now I thought of starting of with that and working my way down, or is 172 not big enough to start ? I would think it is but i would like some help to make sure i can get it right the first time.
thanks

 

Hey a 172 main seem's a bit small to me,I would start with a 182 and go down from there! FEENZ

 

Ok sounds good. I just didn't think to go up that much since my stock carb only had like a 162 or something like that.

 

what about the pilot jet and needle settings? Can someone tell me about what i should run to get me started.
thanks

 

First of, Do you know what your altitude is??I could give you a ball park to start off in

 

o geez....o boy i wuld have no idea.. I live in southern Ontario (canada) if that helps.. But I will look it up and try to find it.

 

I am at 2250 ft and i run a 52 pilot with a 165 main the air screw 1 3/4 turns out if that helps

 

I just got out my dads gps. It says I'm at 110 meters. So thats about 350ft.
