Watch if it has cageless needle bearings on the wrist pin. I know there are 28 needles on my rev, not sure if there all the same. You do not want to drop any down in to the crank case. Good luck and keep us posted.

When you go to take the piston off, seal the case with a rag or something to catch all the needles from the wrist pin bearing. Count them when you get them out, you don't want one in the bottom when you fire it up. I believe there is 28 needles, if I remember correctly. When you put it back together, just put caged bearings back in.

The spark plug was fine and had nothing on it. There was very low compression in that cylinder all of a sudden, and the the sled wouldn't run. That was after riding for a while on lac st anne lake. Have fun with it Bogger, take some pics. Again thanks for the ride and supper last night.

Seal off the crank case with a rag like mentioned earlier and set a magnet under the con rod and it will attract the needle bearings.

You are correct, the new ones come in cages but taking the old ones out requires caution.

if this happens again a trick I heard is to close the gap on the spark plug so it cant spark. so there will be no heat in that cylinder, just air, fuel, and oil. then drive it out on 1 cylinder and a pull sled if your in the hills.
