I've a '98 road legal XR250 (pretty stock). The stock carb is not only restricted but very small, only 22mm. :uh: I found that the gear ratio and engine of this bike is not much different from the XR250R model except for the carb, the exhaust system and compression ration too. I've change the pipe + muffler to the XR250R type but still need to change the carb. I'll need help on this as I don't know what is suitable and good for this bike.
Any idea how to mod this bike? Pls help. :(
Thanks!
