Jetting questions..

[shorgasm]

Need to know the stock
1..Main #
2..Needle position and #
3..Pilot size and #
4..A/F screw turns

Then suggested for slip-on and full pipe.

I'm gonna dig into this carb and check out what this cat has done to it....His lack of care/knowledge on the rolled rear sprocket makes me curiuos as to what he did when the stock pipe was cleaned out...lol

2..Needle position and #3rd
3..Pilot size and #38
4..A/F screw turns 21/4 from closed position!

jetting specs vary from one manufacturer to another. i would suggest contacting the company that made your exhaust and ask them for a jetting range, and then fine tune from there.

with just a pipe, i would start with a keihin 152-155 mainjet. however, the elevation, temperature, humidity, etc all play significant roles in jetting.
