[QUOTE="ashzeigler, post: 1392174, member: 119820"] Hey guys I just bought a 2003 YZ450F. This bike is in absolute pristine condition and has very low hours. Everything is in tip top shape and it rides like a complete dream! It has unlimited power and is perfect in every aspect except the whole "Coldblooded" Part. Now this bike does have a Full FMF Exhaust System and an Aftermarket Air Filter. The bike is fairly easy to start however it usually dies when it is first started. After that I try and kick it again and it just will not cooperate. It takes countless kicks and it even does this when it is warm. If I take a break from riding on the track and sit for a minute or two, then it still is a jerk and will not start right up. Now I have done some research and I guess adding an aftermarket exhaust and air filter can cause these kinds of problems. I guess my question is, how do I fix it? Oh and I had a 2003 YZ450F BEFORE and it was in horrible condition compared to this one that I just got and it would fire right up. Granted it was stock, so maybe it really is the exhaust and air filter. Anyway thank you all for your time and if any of you have a link or some advice on how to get this bike working right it would be greatly appreciated. Thanks a ton! Oh and one more thing, it also over idles.. I tried to mess with that turn nob, but it did not want to work for me. If I even touch the throttle it usually over idles for 15 ish seconds before it calms down and dies or barely stays alive. Thanks! -Ashton [/QUOTE]
