Is the Leak jet a fuel jet or an air Jet

I noticed under the jetting specs that the leak jet seems to be different then all other jets, is this one a fuel or an air jet, I notice as the temp goes down (normally needs larger fuel jets) the leak jet specs also go down, thought this was backwards if it's a fuel jet?

It is a fuel jet. it leaks fuel back into the bowl.

A smaller leak jet is richer because it leaks less fuel.

Got ya, Im use to Mikuni's and i have never seen or heard of a leak jet b4.

Yep - there is lots of stuff to play around with on the Keihin!!!!!

Is this the only MC carb with 4 jets? I am used to 3-jetted carbs. This 4-jet stuff is new to me!

fcr carb. It has all kinds of secrets.......

It also has more than 4 jets, it also has a leak air jet, and a fixed main air jet!

Yeah, I almost wish I had Fuel Injection....... Maybe Next year.

There is a few non-believers here but most of us do as well! :crazy:

The best thing about FI is that it compensates for varying temperatures and altitide, and Atmospheric Pressure, no more needing for tweaking and rejetting and it will gain you a small amount of HP too.......... how can you be a non beleiver.
