Where can i find a recomended jetting for an HMF slip-on exhaust on a trx450er?
My family has ordered from your site a few times and never once been disapointed, but i would like to ask where i could find a recomended jetting for the HMF sport slip on for my trx 450er. I can jet it myself but it would make things alot easier if i knew where to start. Ive asked HMF but they still havent responded. If you have any info it would be much appreciated.

Unfortunately, the Manufacture would be the best contact regarding any jetting specs. Jetting is regional and a lot variables are considered to properly jet the machine.
