I was planin to get a jet kit for my Rancher350 witch should i get. What are the advantages over each other.

 

Get the HMF jets if you have the HMF pipe, they can most likely recommend what you need. I have an HMF full exhaust, but I had already installed the Dynojet kit before I purchased the pipe, so I just stuck with it. It doesn't really matter what jets you go with. If you want to keep it all HMF, then call up HMF, but honestly just go with whatever route fits your budget.
