so i have a trx250ex, let the cousin ride it and he blew the rings a couple months ago, so i had replaced it with a wiseco piston. changed everything out and runs fine, idles fine. but my issue is once were into lets say a good two hours of riding, the head starts smoking as if oil was on it, but no leaks. it shut off on my kiddo this last weekend, and was smoking from the head, and when i went to check oil, little bit of smoke was coming from their as well. i tried to restart when it shut off on him, was almost like the starter relay was going out, or the battery was dead barely turning over. towed it to the camp, tried to start it a couple mins later and started, just didnt wanna risk it breaking down in the middle of the woods.
