Hey all. I'm pondering getting a VFR800 (03+), and want to get staintune cans put on the back end (sounds hot hot hot). Something I'm not 100% sure on though is if you put new cans on a standard system, do you have to "rejet" (I believe this is the word) the bike? what's involved in rejetting and when would one do this (and what would happen if you didn't do it, and it was required)? Cheers!
