I've only had my 2007 for a few days and just coming to terms with mods I'd like to do. PO had pulled the baffle to make more sound. It was too loud for me so I reinstalled the baffle. Voila - more bottom end just like that. I like bottom end (and I liike quiet) so I've decided to leave the stock can/baffle and work around that at this time. I can also tell it's a bit lean, so clearly needs to be rejetted. And that snorkel clearly has to go. So a few questions - Where can I buy jets seperately? Which series jets do I need *with stock can and 4 x 4 mod)? and do I need a different needle or is the stocker OK? I ride between SL and 3000', and always between 45-90 degrees F. If you can't tell, I'm too cheap to buy a whole kit unless I have to. BTW, the throttle response is really crisp on my 2007 - no bog at all.
