Just seeing what's out there for parts for this guy. I've had issues since I bought it a year ago. Looking for advice I have a manual on the way but I'm new to bikes. Had a bobbed out '80 kz440 ltd that took minimal tinkering to get road ready and this a little nicer rather do things by the book and use oem part when possible. I know about ebay and some local stuff but what else is out there for new or used parts? What's the next thing to look into if the carbs and vaccum lines do not solve the issue? What's common things that break and go wrong on these? I know its supposed to be more maintenance free but what have you guys run into? Dont mind my poor photography skills I'm super new to that lol

Sounds like it is running on 1 cylinder most of the time.
Are both exhaust pipes getting equally hot?
Pull all the spark plugs to see what color they are.
