I have a 87 250x, just bought it not long ago, it's not in the best condition but it runs! Recently the chain has been coming loose, so I started investigating and noticed the rear axle is very loose and wobbly. The chain actually fell off today
..any help would be greatly appreciated. I have tightened the chain multiple times, doesn't do much. Kinda new to all this, thanks in advance for any suggestions.

Sounds like you need new axle and/or swing arm bearings. Both are cheap at Rocky Mtn. ATV and both are an easy job. Also, almost any part that fits on a 300EX will fit on your 87 250X, excluding motor parts. Also, you might as well get a new chain and both front and rear sprockets too. If the chain has fallen off numerous times, the sprockets and chain are probably worn. Get the standard rear sprocket and get a 12, 13 and 14 tooth for the front. They are cheap so get them all. Then you have choices depending on if you want low end or high end.
