Trevor's 81 1100 carb jetting issue

[Guest]

mikuni and dyno jet use different sizing eg a 130 mikuni main jet is larger than a 130 dyno main jet

In the old Motorcyclist magazine 1100E header test article written by Joe Minton, he used 122.5 mains with the airbox lid off for all his testing. I suspect this is a conservative number but not sure. Sounds like you guys are on the rich side.

Yes ,but why does it act like it's starving for fuel at 7-8000rpm?

Yes, we know that. Thanks though. I have a chart with the differences.

One thing to try is to take off the ignition cover and twist the rotor with your hand. You should be able to rotate the rotor about 10 degrees or so and it should spring back easily when you let go. If for some reason the mechanical advance unit is binding you can get a hesitation or even a cap on the engines ability to rev.
