My 1978 xs650 hardtail chopper has been running rough after it warms up and I let’er rip on the highway, typically past half throttle. It seems like it starting doing it after I adjusted the cam chain tensioner. Carbs cleaned and didn’t change anything. The main jet size has been fine in the past. Spark plugs getting old? Carbs need sync? Do I need to adjust my points? I do have a small oil seal leak on the left engine points cam shaft. Any advise would help. Thanks
