Has anyone really came up with the solution to the jetting of these Motorcycles ? I have tried most all combinations of main jets much to no avail. The air box is opened I have installed a SUPERTRAP and of course the valve train has been serviced as well as the cylinder bore , Piston and Rings. I have spent plenty of time with removing carbs and such. Any insight for positive progress would helpful as I would surely like to spend some time riding the Motorcycle. Even a carb conversion would be considered. Surely there is something available ? Thanks in advance for the correspondence.
