Hello everyone, long time was reading this forum, a lot of useful stuff and finally got to write an introduction.
I recently got K75S 1988 bike that was sitting for 6 years and seller doesn't know it's history, no keys, no battery, no documents (bike was abandoned by it's owner and sold by the property owner). So I got it pretty cheap.
I wasn't affraid much as just wanted to tinker and throw away in case if it's done.
I was able to turn it on recently, after replacing alternator that was shorted to ground and did a regular maintenance (oil, spark plugs, lubed final drive spline, put a new tires, etc).
Again this forum was really helpful with maintenance and finding issues.
There are still some things to do, I haven't decided whether to restore it as is or make it custom.
