BS34... small round main or large round main jet? was created by ELCouz
Hi,
I currently tuning my Mikuni BS34 ...
I have large round main jet but after a few site ... its says that only small round main jet are compatible to this model of carbs?
I have the two type of jets ... they look identical except top of the jet is larger the other one is smaller...
Quote from streetperformance.com
and for large round main jet (the one i use now)
Did they screw up something or i'm running with the wrong main jets ?
EDIT:
Also here (example):

laurent

I have seen the same $hi+ Yet I have never seen the small jets being used on a Kawasaki. I have on the other hand seen them on h0nd@. They do flow differently than the large head jets.

Here's a great site to identify all types of Mikuni and Kehin Jets.
www.pjmotorsports.com/
And here is an awesome jet flow cross reference table :

Ive interchanged small head and large head jets you simply need to factor in the flow rating differences between the two styles of jets.
