The Motor
The first thing to do was to get it running again. The bike came with a lot of spare engine parts, and I also bought another parts bike so I wouldn't be in too much trouble if something went wrong along the way.
The spark was okay, carbs I wasn't even going to try to do anything with until I got them off and cleaned them, and since it was cranking, I decided to check the compression. The right piston was okay but the left was really low, but got much better with oil so it sounded like I would be buying a ring kit.
Looks like the carbs really needed that cleaning, and apparently this is the only picture I took of the carbs. They were really gunked up though.
I decided to just go ahead and do the rings and deal with the valves after. Cyclinder head off:
Cylinder Off:
Quite a bit of corrosion on coolant system:
Little bit of cleaning reveals a piston!
Stripped bike in the rain:
On to the head:
All cleaned up:
Valves Removed:
Valve removing tool I made:
Need to lap the valves:
Need to lap the cylinder and the head while I have the valves out. I used a piece of plate glass on top of a piece of marble tile as my lapping plate.
Getting closer:
Cylinder looks good:
Put the valves back in:
Reassembling the engine:
Timing and adjusting the valves:
All done and she lives again!
