how isnt it running right?

check the plug after you ride the bike wide open throughout the gears to get a corract reading on the plug (just letting it idle it wont give a correct plug reading...) and see what color it is.

if its running rich or lean, you can go from there. you will know weather to drop or raise the main jet from that..

black/oily its running rich

white/dry its running lean



let us know... :macho
