Clutch locked up on my 82 Suzuki dr250 I am at a loss what should I do.

Your clutch is simply a stack of friction disks and metal plates. The friction disks are splined into the outer hub ring and alternate, one friction disk / one plate / one friction disk / one plate etc. It's very simple to free this up if it's locked up. remove clutch cover. If you are unsure which is your clutch cover, follow the clutch lever cable to the actuator arm. remove the cable from arm and all bolts holding the cover. as you pull out the cover, you will see the arm rotate that's because it's geared into an arm that is connected to the front plate of the clutch basket assembly. You'll see it as soon as you pull it off. now you'll be looking at a round plate with 6 bolts with springs underneath. when you arent pulling the lever, these springs are extended and push the friction disks and metal plates together, thereby locking the inner hub to the outer hub. The inner hub is connected to the crank, and the outer hub is connected to the transmission input gear. So, if pressed together by the springs, your engine running causes your bike to move. Pulling the clutch lever in pulls the spring tension off the plates and allows them to separate. This allows your engine to be disconnected from the transmission. If your plates are locked together you will remove them one by one if you can and lubricate between each plate and disk and reinstalling. Pay close attention to how it came apart. Reinstall bolts and springs reinstall cover, aligning the lever gear teeth with the front of the clutches teeth correctly. put it all together and see if you are okay now.
