Well, i thought my quad was running perfect. But i was wrong. Took it to the coast and the top of head, there is a adapter were a coolent hose connects, i was riding it and i was torking it in 3rd, and the thing blew right off and coolant went everywhere. I have a BOG soon as i try to hit the powerband in 4th. And it OVERHEATS really bad(autozone 50/50 antifreeze and coolant), Anyone Know Wat i can do to fix any of these problems? It has a cr250 head and new top end.​
