Hey guys, I just sold my 03 wr 250 and got the 05 wr 450. Really looking forward to the extra power on the monster hills. I've been reading through lots of threads here, and have used the search feature too, but I'm having trouble with a couple of issues. First, I live in Idaho. The dealer pulled the baffle, (and assured me the spark arrestor was still in the pipe) put in the yz throttle stop, cut the gray wire, and removed the snorkel on the air box (I think that's what he told me). I know he said they did a free mod on the airbox, just not exactly sure. I also had them throw on a 756 in the front. (Does this thing come with a 756 on the rear??) The stock front that came off was a 739, yet there's a 756 in back too! (Didn't pay extra for that one) So yesterday I put on rad guards , and some high bend pro tapers along with a uni filter. Which gets me to where I am now... I don't know if my bike comes with the AIS, or is that just California bikes? I'm heading to the TT store and I want to get my order right. I'm assuming with all I've read that I'll need: 1. JD jet kit? 2. Zip ty fuel screw? 3. AIS removal kit? Thanks a lot for the help guys, this place is such a great resource.
