Hello everybody I Have changed exhaust and put morley jet kit on bike. changed mains,springs and have the clip on the third slot from blunt end if I remember. I also put new plugs in bike and gap them at 35. I have put about 800 miles on bike after all the changes pulled spark plug and here is a pic what is your opinion on how they look? Bike is running strong with no stumble only thing I've noticed is when running 80 to 90 mph and when I back down the throttle getting some backfire. Any suggestions would be great.
