ported 701, stock carbs, FP type 4, what jets????

[keegan]

I have searched for this set up....I know a lot of people think b pipes own and thats fine, I have a type 4 going on my ski and trying to get a head start on what people are running as far as jets? I am on stock carbs 38s, ada head, 33cc domes (im in midwest) 1200ft above sea level. No water injection.

--I have heard using a thicker coupler as well?
--and 135 main jets??

thanks for the help.

I was 140 and 80 felt a slight load up at longer idle but amazing hit on the bottom, elevation of southern ontario, every single bolt on, 37cc on ada head, stuffers, VF2s, ported waterbox, type 4, enhancer.

go to napa and get the 3 1/2" marine exhaust hose (1' lenght) as the stock silicone (blue) couplers don't last too long.
