WR450 How to check for power loss?
Posted August 31, 2011 - 01:50 PM
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.

To give you an idea, I have a '99 WR400F and it will wheelie in 4th with a pull, and will power wheelie in 3rd even without me pulling or leaning back...
If you're still disappointed with the power output, THEN start looking for problems. They are very restricted stock. Even with the header, the stock silencer = no good for power.

CR powerband is quick, more violent, and more potent. But all that is useless on a single track trail.
The WR is no beast; it's a fantastically stable, smooth, reliable bike with a great powerband. Do the uncork, jetting, exhaust and it will be more of the same, and run cooler and smoother too.

Don't get me wrong, I love the bike! It's awesome on the stuff I ride! Any suggestions on an exhaust!
Just open up the stock exhaust and you will be fine. I run the stock 05 exhaust with the PMB insert. Cheap, quiet and it works great. I have an FMF factory 4 in my garage, but its louder and I am no faster or slower on the bike with it.
