$350 · 2 Yamaha maxims, parts or projects

2 Maxims, weathered. Sitting in the weather forever but both are 99% complete, one has a plate on it from 1994. I think its an 84 maxim 650 and an 85 maxim 550? Xjs or whatever maxims are called. Hooked a battery up to either and neither turned over but the electrical systems were both surprisingly intact, got a click out of either starter but didn't pull plugs or do anything so soak or see how seized. I knew the story at one point but bottom line is someone died, paperworks probably attainable but I can write a bill of sale, and maybe go reconnect with the guy that gave them to me and get more of the scoop or the widows name? It was quite a few years ago I should have chased down the paperwork but I think they both sat 20 years before that. Have pictures but nothing special to look at, might be an ok project or parts from someone building a maxim? I was going to cut the frame and make a bobber out of whichever one I could get rolling but I got a $300 Honda and cut that up instead. Rear brake was seized on one of them when we dragged them here. I can help fill tires and push em on a trailer. Let's try $200 apiece or $350 for the pair? Trade for cool junk or make me an offer I cant refuse?
