Riding the whole weekend, came home today rode again for 2 hrs. Running good didn't appear to have any problems. Decided to check the spark plugs the left ceramic insulation was completely missing and less than a millimeter of the tip of the strap looked chipped. The top of the straps had no pieces of metal or sign of detonation. The right plug looked tan and a little with carbon build up around the threads. Only strenuous thing I did to it was 2 top speed runs back to back but even after that the thing felt like it was running fine. All the common fixes have been done recently. Leak down is good, jetting is good I think lol.
