Default Re: Best plug color... really?

i wouldnt gear it up until its run a couple hundred km's.
the carb tuning will make a difference.
i measured my new 66 and the jet is a #74 drill bit size.
i read most success at around a #68.
read up on how to do a plug chop.
fortunately i can clean the plug with my soda blaster to start with a feaux fresh plug every time.

also check youtube,theres a video demonstrating fourstroking.i found it a little helpful.
