Hello all, I recently bought a prowler 650, and soon after took it on a long ride. Went over lots of quad trails etc. Anyway, on the way home, I was on an open gravel road running at 6000 rpm (I know I shouldn't have lol), when the engine suddenly started making a very loud rattling noise. I pulled over and stopped, and the engine quickly died. Anyway, I tried to start it right away, and the motor barely turned over once, did that several times, then it turned over and fired up. Ran fine but continued making a super loud rattling noise.
So, I towed it home, and have since been trying to figure out what is wrong with it. I can't seem to tell for certain where exactly the noise is coming from, but I have confirmed that it is not the clutch, and my valves are within spec. I have good compression, but I noticed that my oil is quite low. In fact I just put a quart in and it is now about the right level. I also took the intake off, and can see that at least the intake valves are not bent.
If it somehow relates, since I got it, it has had a knarly backfire upon decceleration, which I believe to be because there doesn't seem to be an exhaust gasket. Just thought I'd throw that out there.
BTW, the noise sometimes goes away while idling, but under any throttle it is always painfully loud.
I'm guessing the problem resulted from a combination of too many rpms and low oil, so if anyone can tell me what is likely to be the culprit, or if I'm completely sunk that would be greatly appreciated. Thanks so much!
