I recently bought a used 03 WR450, it's very clean and all stock except for a FMF power bomb header and a dual sport kit, as far as I know. I bought the bike cheap from a guy who took the bike on trade and I was able to get the bike tagged easily here in VA. I've put about 40 hours on the bike, it seems to run great, starts easily, the oil looks new after 8 hours of riding, it doesn't smoke and it doesn't have any leaks anywhere. The only thing I don't like is that it backfires on decel. Here is my question: I keep hearing about what a brute these bikes are yet mine seems pretty tame compared to the 03 CRF450r I had. I could barley keep the front wheel down on my CRF, but my WR450 doesn't pull nearly as hard. I can't believe a CRF450 is that much faster, or is it? I'm thinking there is something wrong with my WR, but it seems to runs great. Also, I'm not sure if the grey wire and throttle stop mods have been done, but the pipe is uncorked...Please educate me! Thanks.
