Spark plug and piston after 8 hours
I know it?s pretty early but I just put an RK tek head in so had everything apart so I figured I?d take some pictures and get opinions...I don?t have a ton of experience. I broke the bike in proper for the first 5 hours. About the 6 hours in I was riding through a recent forest fire and was in about of foot of thick wet ash for a good hour. The bike started to overheat so i let it cool down and everything was good after that. I did lose a little bit of coolant from overheating, maybe 4 ounces or so. Here is a picture of the top of the piston and the spark plug.
