That endless list of other things is what I am interested in. I've tried re-jetting and cleaning the carb with no success. I thought I had all intake manifold leaks fixed but tomorrow I want to hook up some low pressure compressed air and check for leaks with soapy water. $10.00 of plumbing supplies today got me a way to connect air pressure to the intake. I know my VOES switch is bad. Waiting for the part. I put vacuum to it with a hand pump and it would not hold vacuum. If it was working, I believe it would hold a few inches of mercury and I should also be able to hear a not very loud click. I put in new spark plugs. Sometimes it runs perfect, but when it wants to go into its fits it will do that. So, I am interested in that endless list of other things to check. If I have a good VOES and it's hookup up right, no manifold leaks and no vacuum leaks, that will be a good start, but what else? I just don't know where to go from there. Part's cannon? New plug wires, then coils, then ignition? Do I really have to go that route? I just don't know what else it could be. I believe it's getting plenty of gas from the tank. Sometimes it will run full throttle just fine, but it doesn't like running right off of idle, cold or hot. That might be the VOES maybe. I just don't know. What it will do fine sometimes is go down the road at 60, and sometimes it will run at full throttle just find too. It just doesn't like getting there, but once there it will run fine at full throttle. I just don't know, and it likes to idle well with no change, ever, which is why I doubt it has air leaks from the manifold, but I want to know for sure.

If your bike is fuel injected. you'll need a "tuner module" to adjust the fuel/air mixture.
