I have just installed an Athena 480 kit with 10.7:1 compression in my quad as well as an HRC cam. I run a HMF full race exhaust and a stock airbox lid. I am having some trouble with jetting and was wondering if there was anyone else out there with a similar setup that could give me a place to start? thanks a lot.
