I bought the Muzzy Slip on pipe for my KFX 400 today...This pipe came highly recommended from all the dealers here in the Richmond area. Also purchased the Dyno Jet kit. I can't for the weather to break so I can take this thing out and give it a good run for it's money!!!!

 

What jetting are you using with muzzy??

 

With just the pipe I used a 150 main jet and when i added the Uni filter I went up to a 155.

 

were you using the dynojet kit, or just plain mikuni jets? I've heard that they are different
