My 1972 cl 100 while riding locks up back tire and then skids to a stop and shuts off what is the problem
If you are in gear when your rear tire locks up, that will also stall out your engine. Conversely, if your engine seized up while you were in gear, that would lock up your rear wheel from the other direction. However, as it sounds like you can restart your engine, that's probably not the case. One way to check is that if your wheel starts to lock up, immediately pull in the clutch. Your engine should keep running, even as your rear wheel is skidding along.
If the problem is in your rear wheel, there aren't a whole lot of things to check. This bike uses a rear drum brake, so check to see that's not binding in any way. I suspect that it won't be. A stronger possibility is that your rear bearings are worn out or insufficiently lubed. If they get hot enough and expand enough, they'll seize up your rear wheel. Pulling the rear wheel and cleaning / lubing the bearings would eliminate this possibility. If the bearings are dark colored and/or have flat spots, that's a sure sign that they've been abused and need to be replaced. A third possibility that comes to mind is that your chain and rear sprocket might be excessively worn. An old chain, with one or more rusty links, could kink up and jam. I once bought a bike with a nasty old chain and it did this on occasion. It would work fine for a while, but then kink up. Replacing the chain (and the sprockets, because they, too, were very worn) solved the problem for that bike.
