Re: jetting
Jet it yourself....run it hard and immediatly shut it off. Take out the spark plug and inspect it......
black=to rich (need smaller size jets)
Tan/Grey/Brown=jetting ok
White=too lean (need larger jets)
Why do you have to jet it anyway???? Unless you put some aftermarket parts to increase performance you shouldnt have to really mess with it.. Usually then its just a quick adjustment of the air screw.
