Been lurking about for a few months now reading all about tips, tech, setup, and maintenance of the 02 450r I recently purchased. By far the best forum I've come across and it's been incredibly helpful in learning about what it takes to keep the new thumpers ticking. This is my first 4t since my XR80 back in the early 80s. Last bike was a 1997 RM250 about 7 years ago and I rode 90% mx tracks in the louisville area (just for fun...never raced). So I had been looking for a bike to rebuild and ride and I came across a beat up 02 450r for $800. Needs a lot of love to get it back in good shape so I thought I would start and keep a thread on the project. Plus it would be the very best way to find out exactly what I should do from folks with tons of knowledge and experience. I'm wanting to put together a solid bike that I could possibly race in a few Vet class races in the future. I'm 41 years old with above average mx skills (for an old man). First and foremost I'm going to strip it down, clean it up, and fully assess the situation. I already know she's going to need a minimum of intake valves. Clutch feels pretty sticky as well (pull it in and you still get quite a bit of resistance when rolling). Previous owner spray painted the frame and swingarm black so I'm either going to strip, polish and brush them back up or polish the swingarm and do a bed liner on the frame. Tires are shot, as are the chain and sprockets. Probably going to be the 536th build thread for an 02 so most won't be interested but who knows, someone might and I know I will need some helpful info and opinions along the way. I've got a reasonable budget for the build but the wife pregnant with twins so it won't be a super duper high dollar build. I just want something that will be fun on the mx track and competitive enough to make it a fun weekend if I do wanna ride in the vet class a few times. First off I'm going to get the intake valves up and running. I've read that some folks swap an 06 head while keeping the 02 cam. If the valves are shot and need replacing would this be the best route to choose or would a SS valve kit be just as good an option? Thanks.... and sorry for the incredibly long 1st post.
