Do you know if the cv carb slide has been modified? Baja designs and i think Dynojet have a kit to do that, about $20. These bikes are pathetically lean stock for emissions reasons being a factory dual sport.
I canned the cv carb for a 41mm mikuni flatslide, k&n filter, 102.4mm 10.25 to 1 comp piston for 675cc's, megacycle cam and big gun exhaust. If you want to raise the compression you pretty much have to do a cam if you want to use pump gas.
I couldn't get the link to work but if you go back to about page 4 and read the thread on the xr440 kit there is a ton of good info, best of luck!
