Default Identify my ATV Model By Engine Serial?

Hello all, new here. Just bought a older Yamaha from a guy. It look like it stepped right out of Mad Max....heavily modified frame, paint, etc. Problem is, no VIN in site (check the whole frame everywhere..took all plastic off). I DO have the engine serial still - 52H-031431. If anyone can help me identify the year, model, engine size, and any name it had back then it would be much appreciated! I need to find a service manual to fix a no spark problem but without knowing anything about this quad the service manual is hard to find. I'm guessing she's mid 80's. Thanks in advance for any help!

Default Pics to Help ID

Sorry, good idea. Just threw the engine serial out there first not knowing if someone could do it from that. I fixed my spark problem with a new coil but I would like to order a few things for the bike like a forward/reverse shifter lever, etc.. so anyone who can ID the year/model/name/engine size of this thing it would be much appreciated. Thank you in advance, here are some photos.

Default 85 or 86 YFM200N

I believe it is a YFM200N either 85 or 86. The beat to heck VIN on the bottom of the frame has an "F" somewhere in the middle of it (can't decipher the whole thing). Does that mean it is an 86? Does YFM200N sound right?
