What jetting?

[02Blaster02]

So i have a fmf fatty pipe with powercore 2 silencer, and im at a 250 main jet. I just installed a oil injection block off kit, and im going to the dunes at sea level, so what jet should i be about, without plug chopping?:-/
Oh yeah and I also still have the airlid on:-[

 

[Awk08]

there is no sane way except plug chopping
the 250 main is more than likely too small to begin with

start with a 310 and work down 1 size at a time,
just until the rich bog goes away

 

[89blaster89]

i would think a 260 would be safe

#260 would be too small without oil injection.

Pre- mixing itself at 32:1 calls for 1 or 2 sizes arger jet.

 

[89blaster89]

do you have your airlid on??

 

[02Blaster02]

yeah i forgot to add that, but its there now

 

[wwholden]

Throw out the lid and put a 290 in there. That should be pretty close.

his dad wont let him take the lid off, so hes stuck with it for now you really think 290 though with the lid would be good?? or rich?
