Hey,

I bought a 2006 KLX250s in may 2008. Its a nice bike, but I am aware it is not living up to it's full potential. I found The KLX free mods on the internet, but my Bike is made in Canada and nothing short of cutting and welding the exhaust will remove my baffle and such. I figure instead of doing that i'll just buy an aftermarket exhaust. I just had a few questions:

1) Does a header pipe make that much of an improvement?
2) Has anyone done/seen done a exhaust upgrade on a klx250? I am aware I will have to re-jet the carb and play with the air/fuel mixture, and have knowledge of how to do so, except on what kit to buy, or needle sizes.
3) I recently played with the gear ratios for the chain. I installed a 12 tooth from sprocket in place of the stock 14. I asked at the big shop for the parts i needed and recieved the sprocket. I had to machine a spacer for the one, and it doesnt have the rubber guides built onto it either. How important is that guide. every thing seems to be running fine, i was just curious?

Thanks guy. Any help is much appreciated.
