Hey fellas. I have had my bike up and running now for about 2 weeks now and have put 200 miles on her since she sat for a while. I am having just a few issues that I want to have a second opinion on. The bike starts up very well after installing the pamco high output ignition. I am getting a backfire on the left cylinder on decel but only when i ease it back. If I close the throttle completely she usually wont backfire. Seems to me that if i hold the throttle at a certain position she will backfire...possibly a jet issue?(mind you I have adjusted the air/fuel screws) Second whenever i use the choke it sets the idle at about 4K which is a bit much. Is there a way to adjust the choke so it idles a bit lower? Third, the engine burns oil but only at certain times. Obviously this could be a piston ring issue but I also feel as if oil is seeping its way down to the combustion chamber from the valves after I let it sit. It's very weird that she only burns oil at random times and then other times she doesn't at all. Lastly is the exhaust leaks. I have replaced both exhaust gaskets and she still leaks at the heads. Is there a possibility the pipes are just wrong for the bike and they are not seating properly? It's driving me crazy.
One other weird thing. On the right carb the air/fuel screw is working properly to there if i screw it all the way in the engine will shut off and when I screw it out she richens up but the left carb screw wont change a thing when i screw it all the way in and back out. I have cleaned the passageway as well. Thanks fellas.
