Last night I re-jetted my bike for the warmer weather....1/4 turn in on the fuel screw and went from 182 main jet to 180. Bike runs 100% better at idle and off the bottom....seems about the same at full throttle...very happy with the way it runs..
I couldn't really do a proper plug check since it was 10:30 at night and the neighbors already hate me so I just rolled on the throttle in 2nd gear till I got wide open and then shut off. I checked the plug and it was basically white...not in a bad way...it just looked brand new. The plug had only had 3 rides on it prior to this. (sorry no pic).
My question is every time I've pulled a plug out it has been brown to black...never white...I find it hard to believe the bike would lean out significantly by only going down one jet size...am I just being paranoid or is it OK for a plug to look this way? Is there another way to know if I am too lean??
