Hoping for alittle advice. Ok, here's the deal. First, there's nothing wrong with the bike currently, it's running great. But, I figured that I would pull the spark plugs and check them out. When I looked at them they were both equal with a "dry carbon apperance", not wet at all. I would call this "slightly rich". Here's my question. Should I just replace the plugs with new and watch them over this summer? Or should I adjust the pilot screw(turn in a touch on both carbs, I think this will lean up the mixture). I'm leaning towards if it's not broken don't fix it. I just don't want to mess-up the carbs beyond my skill level. Addition information-My wife gifted me this bike this past spring, and the carbs were professional cleaned and synced about 1 ago. Previous owner really didn't ride it too much, but did idle it a lot when showing the bike for the sale this past spring. He was using 87 octane and the air filters were fairly dirty at the time. I have cleaned the air filters well, cleaned the pitcock fuel filter, replaced the fuel lines added inline fuel filters. Running 93 octane now. Your thoughts!
