I plan on ordering a pipe/clutch kit from HPD Monday. I have'nt talked to them yet and I was wondering if they send a main jet with the kit or does it need one?
I already have the airbox modified and had the cylinder bored .20 over. I noticed when I checked my spark plug that it has a grey tip, not brown or black. I think its running a little lean? Any input will be appreciated.

 

It should come with a few jets and you will have to test them out i wouldnt run it lean for very long or u might be goin .40 over

 

The proper color should be a light tan or slightly darker brown. If it is gray, you're running too lean.
