I am getting ready to order an hmf pipe for my 04 vinson, I've read that there are a few combinations for the jetting, I was wondering if anyone knew the best jetting to go with for this pipe? And has anyone seen significant power gains after installing the pipe and jetting?

 

HMF Jetting page

Check out the HMF link above. They list all the jetting they found worked here in Cleveland. If you are under 1000ft I think you'll be ok with what they list. They list a 142 Keihin Round. If you have ANY questions about jetting I think you will be best off if you ask them on HMF's site. They have a forum that you can ask the HMF guys directly any questions about your pipe, or just give them a call...1-866-HMF-PIPE.

Which pipe are you looking to get? Utility? Penland? EcoSystem?

 

Thank you for the info! I am going to get the utility series with the quiet core, I live in Ohio also (athens) So hopefully what they say will work , thanks again.
