So picked up my 1980 xs650 yesterday and have started poking around to see what needs to be repaired. I have the new battery charging while I upgrade the fuse box since a glass fuse was blown and it was jerry rigged up anyways. Previous owner said carb needs to be tuned but judging by the air filters deteriorated state and a rubber seal deformed I'd say it's time to get some pod filters. I ended up getting it running after I charged the battery and ran it down the road. I can tell it needs some adjusting but it was fun to ride it.
