08 250sxf knocking, need advice..

Recommended Posts

Bought the bike knowing it had a knock or (tick) as I originally thought. Valves all within spec, the bike probably has around 10-15 hours on it. Replaced cam chain tensioner to dirt tricks model but no difference in motor noise.

Now I am sitting with the cases split and crank out of the motor but I just don't see any wear or bad bearings. Piston and cylinder look brand new with excellent compression. Crank has little side to side play but no up and down. Got a second opinion at a local shop and was suggested to replace crank+piston as set because of possible uneven wear. I'm comfortable doing this but just looking for advice. The knock was loud enough that I definitely expected something visible to be bad, but I just don't see/feel it.

Can post pics or measurements if that would help anyone, thanks.
