I have a 1974 Honda CB750 four. The bike idles fine, and revs well in neutral. The problem is when I'm trying to get going or accelerate. Unless I'm going with a really strong wind to my back, or down a hill, it is a chore to get the bike up to 60 mph. Also, If I'm trying to accelerate, and open up the throttle all the way, it starts to die out.
The exhaust is very rusted. I don't know if it is rusted enough so that there isn't sufficient back-pressure, or if that would even affect it.
any help is appreciated.
