First off I tried searching but don't have unlimited access to a computert, so after 20 minutes of no luck searching I decided to post. I just picked up this 2004 wr450 from the original owner. The bike is really clean and he claims the odometer has only rolled over once which would put the bike at 1800 miles. I believe him because it looks so new, it still has the factory rear sprocket and very minor paint rub by the shifter. He has only upgraded to a drd pipe and that is it, no free mods yet. He went on to explain as I was purchasing it that it had sat for 3 years without a ride. The first thing I did upon returning home was drain the gas which was way bad. I refilled with new and tried to start the bike. I got it started with the choke but it runs really bad, and will not idle once the choke is off unless you give it at least half throttle. The bike bogs when you try to accelerate for 2 to 3 seconds backfiring 4 to 5 times before it finally picks up. I figure I am just going to get all the necessary gaskets and jets and rebuild my carb. I was wondering if there are any kits on the market that contain all necessary items for a rebuild or if you guys have any suggestions on other things to do or check while I have the carb out. Any help or ideas will appreciated, thanks. Oh yeah he siad the dealer in vegas jetted the bike for local riding but I am not sure of the size of the jet.
