Hard knocks?

I own a 95 Wolverine and, occasionally, there is a knocking noise coming from the crank case. I can feel it on the left side of the motor where the gear shift is. I changed my oil and found copper(?) shavings on my oil filter. Very fine...you couldn't feel it but you could, definitely, see that it is bronze in color. It, usually, does it when the motor is under a load like motoring through some tight woods or under full throttle. My guess is that it is the link inside of the crankcase for the front axle or maybe a clutch is coming apart. Any ideas? I want to get this repaired before I put a big bore kit in.

Re: Hard knocks?

hmmm...the only thing i can think of that has copper colored metal is the clutch....unless you have a shaft that is bent and slowly burning up a bushing inside...what oil are you using? Could the oil be thinning out some??
Either way it sounds like a tear down may be in order...

Re: Hard knocks?

I was using yamalube. Now I am using Castrol full synthetic. I suspected the clutch. I hope it's not a shaft. I plan on tearing it down when I return from Co.
