You guess correctly....motor is siezed. Get out the wrenches it's going to require that you completely rebuild the engine if you ever want it to run.

go to the auto parts or hardware store and buy a couple of cans of something called pb blaster.

Then pull the spark plugs (you may have to spray on them to get them to turn the middle plugs are going to be a pain) and spray the shit out of it into the spark plug hole. Close it back up and wait overnight. The next day go out there and do it again, wait another day. The next day go out and with the bike in neutral put it on the main stand and climb aboard (have the plugs out and the cylinders full of pb blaster. Pull all your weight on the kickstarter and wait. If it doesn't give right away respray and wait another day to repeat.

If you can't find pb blaster go to the auto parts store and get diesel oil.

If you still can't get it loose, pull the motor turn it upsidedown, and pull the bottom of the case off and make sure the crank is not rusted. If it is, you will have to get another motor.

I hope you got a title or registration or some kind of paper for this bike because without that he should have paid you to take it away. Not trying to be mean, just telling it like it is. Sometimes a Free or $60 bike is no deal at all, espically when it has been sitting outside for 26 years.


edit: oh yeah and don't bounce on the kick starter, you are liable to damage the return if you do. If it won't move with your full body weight on it, it won't move. Also if she give be ready so you don't fall over with the bike - happened to me with my 750 last night and I have been limping all day.


Edit part deux: The rings will be junk from this process but somehow I doubt that is the least of your worries. The clutch has likely rusted together too BTW and will have to be pried apart. After it breaks free drain the oil to check for water - that will tell you if the bottom end is shot.

If you decide to not continue with the project, I would be interested in buying some parts--seat, maybe tank, side panels, mufflers, front fender, etc. for my 550.

I got mine for free with a title, and it turns over with both the kick and electric. I was just lucky I guess, but free will still cost $500 at least in the end before it is on the road.

I don't want to jump to any conclusions but 20 years is a freakin long time to sit outdoors for any bike. How about some pics so we can see how bad it is and tell you whether it is worth saving or not. At some point it doesn't matter what you are going to do with it (stock or modified) the bike is not worth saving.

if you had rust below the pistons, then the chances are good you have rust in the bottom end of the bike. If you got a spare motor, just use that whole motor.
