As soon as we get the first FSR250s one will get sent to FMF and Pro Circuit so they can build some spark arrestor type mufflers.

They demo model we had here in the states the muffler was a prototype. We actually built it ourselves with parts from FMF as the unit that was sent with the bike had no internals at all and was for "photographic purposes only."

The European models will come with the GasGas performace brand called "REVERSE" and it will meet European sound standards, of 94db I believe, but without SA status.

The FSR250 we rode didn't need a whole lot of help in the performance area other than some help with jetting to eliminate off idle bogging.

We used a JD jetting kit and blocked off the "leak jet." If we would've had the time, as we had to ship the bike back to Spain, we probably would've looked into trying an engine side carb "divider plate" as well.

For performance modifications I would go to ThumperTalk.com and look into2006 Yamaha WR250f engine and carb mods. The most obvious ones would be accelerator pump modifications and to go with the stock YZ250f valve timing if you want more aggressive power.

Myself I would go with the JD jetting kit, divider plate and accelerator pump mod and leave the timing alone.

I would also most likely play with the final gearing a little as well as the five speed gear box, even with wide ratio gearing, could most likely be changed to meet your style of riding better.
