1982 Yamaha XS400 Seca

Up for sale is my 1982 XS400 Seca it has 33,000+ miles on it. I have been running it for the last 4 years. It has about 1000 miles on new o-ring chain and sprockets, ew piston rings last winter and new battery last spring. I wanted to add that with a bike that is thirty years old it is going to have problems one thing that it is doing is it has a clattering noise when it first starts once it has run for a few seconds ithe noise calms down This past summer near the end of the riding season one cylinder was cutting out I believe it is the spark unit which I have replaced with a new used one off ebay I rode it a couple times and it seems that the spark unit fixed it. As far as a warranty I am willing to work it out if you have an issue within a reasonable amount of time.I would prefer local pickup. Please ask any questions you have before committing to buy tjis bike
Thanks for looking
