Had a stage I installed by the dealer with a SESPT dyno tune at the 1000 mile service. From the beginning, I have had a exhaust pop when up shifting when I let off the throttle. Now at 1300 miles, I checked the oil and noticed a slight gas smell on the dipstick, the oil does not seem diluted but Syn3 is kind of thin to begin with, and it has a slight darker color than new. I also have a slight black sooty color in the mufflers, no raw gas smell in mufflers. Bike runs OK, other than my poor dyno numbers (previous post). I stopped by the dealer today and the service rep said to drive it, this is normal. Do I drive it or look for problems? Sorry if this the same old song on a different day.
