Ok this bike has fought me ever since i bougt it. Ok so far I have redone the carb put new intake valves in(originals were cut and sucked up into the head. After these two fixes the bike ran great. Over the wkend i took it to a local race. During the time i came off a jump and then went into a turn and the engine(i think) let out one loud tink. After that it lost power. You can ride it for about 10 secs then it shuts down. The engine now has developed tinks that come from the engine.(I think) I have no clue what is wrong unless it is just over heating. If anyone has any ideas can you please help.

The bike is a 1987 Mojave that has been rebuilt mutiple times.

Well I found out what it is, the head is junk. The last owener recut the valves so that they would kinda seat and now the head just keeps pulling the valves up into the head.

The quad is now fully functional again and it only cost me $175. I found a guy who broke the kicker gear on an engine and he didnt want to split the case so I just took off the top end and dropped it on my engine since the rod seems to be in good shape.
