I just wanted to say thanks for the welcome. I finished breaking in the bike this weekend and am ready to start wrenching - beginning with the throttle screw and exhaust. It really sounds like it wants to breathe more. I think this is the start of something good!...all 3 daughters argue over who gets to help dad clean the 'dirt bike', and (much to my wifes dismay) all 3 want to know when they are getting THEIR dirt bike! They all started jumping their bicycles over a dirt ramp in the front yard and asking how much air they got ...priceless!
