Just went to the dealer and got a 07wr250, and the guy said that the bike comes very restricted and i did some research on TT and I found that a lot of smog stuff keeps the bike corked... So he said to but the AIS kit. To me the instructions and i don't want to pay 85$ per hour for them to do it... anyone with maybe pictures or something would be great and/or instructions Also does it mess with jetting and so does taking out the baffle, removing gray wire, and snorkel? I'm also trying to get new seat foam as I am only 5'8 and find it hard to touch the ground Would a yzf seat fit? Would any yzf 250 exhaust, and header fit on it? would a wr450's exhaust muffler and header fit? I have to many questions about this beautiful bike. Someone willing to take their time with me is awesome.
