Clunking Noise! Help

[nu2it]

Well guys I just found out that my 94 polaris 750 sl is out of commision, my boyfriend and friends killed it. We just got the pair and I hadn't even got to take it out yet. Died in the water, toed back in, now a clunking noise. This happened yesterday I was told 5 minutes ago. Not happy, any clues? I could sure use some help! Trading Boyfriend for motor!!!!!

Have you heard the noise? Can they discribe it better.Can it turn over. Does Ex Boyfriend know How to turn a wrench? Were are you located at? We need a little more info.

Thats what I was thinking, Thank you. No more riding for him cause I will be taking his. I will probably be working on it soon. I will need more help I'm sure. I hate the fact that we just pull and put back in his motor. I guess I will be really smart by the time I'm done. Thanks again

Yes it turns over and it starts, but sounds like a knock, checking compresion now. He thinks connecting rod or piston pin. but knock is pretty loud.
