Hello I'm new to the forum, I just got a 1981 Yamaha xs650 from my cousin and as I received it has a surge at around 3000 ROMs. The tone of the motor changes and it surges ahead almost like a 2 stroke bowerband kicking in. I was thinking timing or tuning??

Welcome, alov. You'll need to give more information on your bike before you get any useful replies. First off, what ignition system does your bike have--breaker point, factory electronic with pickup coil on the alternator stator, aftermarket electronic with electronic advance, or aftermarket electronic with mechanical advance?

so i am trying to figure that out, there are no points i can see. im thinking its electronic but do not know exactly where to find it? i also have an issue with the right cylinder firing it isnt running and seems to be a knock when the engines idling.
