Put in a brand new Champion plug gapped at .30. Took it out for 15 minutes, half at medium speed and half at open throttle. I am still breaking in the bike and have maybe 75 miles on it. I am using synthetic oil at 25:1. Does the plug look bad after just 15 minutes, or should I just chill until the break in period is over. Runs and idles great, but does seem to choke out at little over 90% of throttle. Thanks guys!!
