I am in the marine and snowmobile and motorcycles business in northeastern Wisconsin. I winterize a lot of things up here and have found these few things to be beneficial to a motor and bike. Get some gasoline stabilizer for the gas, and use the recommended amount while filling your tank with a high-octane fuel. Use a fuel that is a little higher octane than normally used and run motor for about 5 minutes to get it worked through the carburetor. The reason for higher octane is that gas loses its octane potency after sitting over several months. So having a higher octane offsets the loss of octane over the winter, and your motor will have good explosion power when started in the spring.

When motor is shut off for the last time before the next step, you should choke the motor to get an extra shot of gas and oil run though all bearings in motor that will keep the lubed for the winter. Remember do not run the carburetor dry because when you do, that dries out all the rings, bearings and carburetor parts, then everything gets condensation and starts to rust.

Next, pull the spark plugs out and spray some fogging solution (It can be purchased at any automotive store.) in the cylinders or cylinder for about 10-15 seconds. Spray into the plug hole then put the spark plug back in, and kick motor over 2-3 times to work the solution into the rings to keep then from sticking.

Make sure you pull the battery out and keep a trickle charge in once a month that will make it last a long time.

Then, in the spring, maybe the only thing you may have to do is put in a new spark plug.

One other thing that might be a good idea is to change the crank oil. Some choose to do it in the fall; some choose the spring. I feel with condensation, that you should change it in the spring. This is because any water that might accumulate over winter can be drained out with the oil, and you can start out with fresh oil. Some people put new oil in during the fall in order to have fresh oil over the winter, but what about condensation? Do you want to run that in you motor in the spring? Think about it, and use your best judgment. If you do change it in the fall, you might want to go ahead and change it in the spring too. I think you'll do the right thing and make you motor happy for spring. Happy Riding.

Project Notes

I finally got off my butt and started restoration of my '68 ML 125. I took the engine up to Jerry Barbour in Macon, GA for a rebuild, and I've rounded up several of the needed parts for the rest of the bike. Hopefully can get it largely done by spring. I also picked up another partial '73 TX 125 to go with my other partial one. The new one is in much better shape in some ways, so hopefully can at least bolt together a running, if rough, bike to hammer around on.
