Well I picked up this 00 gp1200r with trailer and title for $200 couple months ago. Brought it home and started tearing it apart. Middle rod went thru the case. Bought case, crank, piston/jug and gaskets.

Put it all back together last night and took it out for a test run. Started right up. Idled around for a minute or so and then gave it a little gas. Motor lasted for about 5 minutes tops. Brought it home and started tearing it apart.

So damage this time is crank, reeds, piston/jug.

The center two bearings on the crank won't turn without force. Do I have to replace the whole crank? Or can someone replace the bearings?

Another thing is when I hook up the kill switch should the power valves move?
