I just put a 34mm keihn carb on my 1983 250r. What size main jet should I start out with, I have a 150 in there now. I don't have time to take it out tonight and was wondering where to start. It had a 31mm on there with a 130 main in that. should I go down to a 130 or will that put me back where I started? And What notch should the needle be set on? Help me out if you can.
