got my motor on the bench, 06 yz450f. top end is off, piston on rod, timing chain and flywheel off. I could only turn the crank 2.5 rotations in either direction before it gets jammed up on something. Is that normal? I think not.
I disassembled it cause I thought I had rod bearing go bad on me, but I'm starting a different topic about that in the general forum. Thanks
