Motosportz steering damper & Keihin PWK carb. I have ridden off-road bikes for almost 30 years and finally got around to trying a steering damper. I have had a 02, a 04, & now a 07 WR-250. The stock suspension on the 07 works better than the other two, but I was going to have it revalved until I installed a damper from Motosportz. I know that dampers are not designed as a suspension fix, but on my WR it made a huge differance. Without the damper, the front end wanted to wander in the slower rocky sections & you never knew what it was going to do. With the damper, it has a much more planted feeling & not so unpredictible. As with the suspension, the carburation on my 07 was better than the previous one's. When I had the PWK on my 04, it didn't run much differant than stock. Not true with my 07. It did away with the soft spot or transition between the bottom & mid which is what I was hoping for, but also gave it more power everywhere, almost to the point of to much. It is by far the best carburated WR-250 Iv'e ridden. I am hoping that better milage will also be a result from using the PWK.
