I have a 28mm keihin and the jetting numbering is very confusing to me
The kehin jetting numbers are. Lower #'s than the mikuni#'s
I run in the 160 range
Up or down according to temperature
That's with a ported stroked big bore
Basically Kehein main jet numbers are 1/2 of what Mikuni numbers
Pilot jets are 2X
scroll thru this thread and see if anyone else has reported on the 28 Keihin
I ended up getting some jets for the mikuni... now I have to get a idle screw mine fell out... I'm wondering can I get the same idle screw from motion pro and just put a spring on it instead of the locknut... will it stay in with just a spring on it
Only use. Genuine oem parts!!!!
It's the idle screw in the tors delete kit... fell out dont really like the jamb nut... so was thinking about taking the spring off my keihin idle screw and putting it on the mikuni idle screw... I'm still using the stock carb
Now you know why it had a jam nut.
Vitos performance might have one?
