Eurika!! I reread the K&N instructions and realised I needed to put snorkel back on and I was running it without it. It runs fine with the Snorkel back on!!! THANKS FOR ALL YOUR HELP!!! I learned a lot in the process!!! On Mar 29, 3:49 pm, Snookfever <[email protected]> wrote: > I did not find anything in the slow jets. I did find some particles in > the bowls.

How about the brass tubes above the mains ? At 3~4K you start to depend on the next circuits to supply fuel. Since these have enricheners and not chokes, you can add some choke to make it run richer. Now if that helps, increase the main jets to 120. You don't specify if the stumble is just that or it is popping. ?? A pop is a good indication of lean. If it truly is that lean, you could'nt get it to go above 5k at all. Getting it up there slowly means to me (IMHO) that the air speed is too slow to pick off fuel. That's where the choke addition comes in. If that makes it worse, let me know. A high air flow filter actually causes a slowing of the flow. Untill they repeal the laws of physics (Obama just might) high speed air works best. You do have the lid on the air box ? With the snorkle ? I hope so.
