Start with the pilot jet and air screw and go from there.

Was there some reason you chose 45:1?

Did you perform a leak down test? Did you check the bore for being out of round? Reeds and packing? Ignition seems okay? Have the ports been altered? What kind of pipe and silencer? Air filter is good and not over oiled? They can gum up and not flow.

Not sure what kind of pipe you have. If you have stock pipe it is lined with fiberglass that soaks up unburned oil. After you get jetting correct, it will still smoke and spooze for a time until the surplus gets burned out. In short, there is a lag on stoping smoking and spoozing until the pipe sort of burns out on the inside. With a stock pipe this may take a while with some hard running to get it all leveled out. You are on the right track to get the jetting worked out. I suspect that you may be still a little rich on the pilot, but maybe lean on the main. Ride safe---John
