Cool!!! Thanks for the input and humor. Plugs tell a great story! My read key is wide open to redline in a 2nd or 3rd gear and then kill switch with clutch pulled in. Roll into the garage and remove and evaluate. Toasty brown is my goal! And I'm close, long term miles tell less but are of importance. As for fancy expensive plugs, save your $. NGK standards every year make a happy bike, car, etc..... My thoughts and experience! Feel free to chime in.
