Alright all you hot shots, i'm looking for the low down on the mods you've done to your engines. I want to know everything you do about prices, where to get the work done, and what other mods are needed to keep things running smoothly. Help me out here if you don't mind.

 

The guys at Poweroll in Washington state have been doing 4-strokers for a long time. I have only bought a few things from them (big tube headpipe & free flow airbox lid), but their brochure has lots of stuff for thumpin' your 300, like big-bore kits and stroker cranks and cams too.
Have fun & ride hard
