My buddy just gave me his 650r for next to nothing. I'm really excited. I have seen the writing on the wall (gas) and am going to put a Trick Dual Sport package on the bike so I can ride it to work. Gas Saver + lots of fun. I have been researching and two things come to mind that have a lot of different feedback. One: What other type motorcycle rims are compatible with the 650R? Two: What the he?? is the Air Suction Valve? I am going to uncork the bike and get rid of un-necessary parts. Is the latter one of them. I live in the highly civilized area of Clarksville, Tennessee where these types of parts don't matter. I am leaving the country for a few months which affords me time to figure these issues out (possibly) before I really ride it. I rode the bike tonight, which has been sitting a while and it needs help (carb gunk). I plan to order the specific parts to uncork it, plus protect it. My wife is pissed since I haven't sold my YZ250 or CRF250X. I have another kid on the way (this makes two under two) and plan to have the XR as my one outlet I can ride out of the garage to maintain my sanity without taking the whole day to trailer etc.... Please help a fellow brother in need. I'm honored to be part of the BRP clan and will contribute back as I become educated. Thanks Dirtmissile.
