If you can't pass a wire through it, it isn't clean. That's what I mean. The wire size is .0011" for a #35 slow jet. I don't care if you can blow through it, see through it,etc. If a .0011" wire doesn't pass through it, NG. If you want it to work with a K&N, test that way.

I soked them in acetone and blew them out with compressed air. I pulled number 4 plug it was light tan on the insulation with some black on the threads. Should I run the plug test with the stock filter or the K&N? On Mar 21, 3:03 pm, Dennis Hammerl <[email protected]> wrote: > Did you wire out the slow jet ? And yes, I have a method of enriching a K&N filter. I have one in one of my 700s and it required no changes but I did a neat stunt and gave it more bottom end. My 700s pulls hard from 2K up. Made huge difference for me. I granny around a lot and spend too much time in traffic. Less shifting now. To understand it, you need to grasp air flow dynamics. The British did some good research on it back in the 50's.

Very tempting to do.
