Man this thread is awesome. I am trying to open up my stock XRL. I'm an all around noob, but am pretty mechanically inclined. Somewhere in this thread some one basically said to take baby steps. Do Dave's mod, re-jet, open up the intake/exhaust, and then see if you want to screw around from there. I intend to take that advice. I'm gonna do all that but can't drop $$$ on exhaust just yet. Can anyone tell me what are some good jet sizes to start out with, for a stock XRL, de-snorkled, uni filtered, and Dave's modded? Didn't mean to interrupt the topic of thread. Thanks for any help and a good run of info already.
