I recently picked up a GL1200, the previous owner was at a loss as to what was wrong with it after putting timing belts on. I found that he had the left side on incorrectly and ended up replacing the cylinder head. I did all this work myself. But now I have few questions about my bike. When I start it, with the choke it smells real bad and hurts your eyes in my garage almost. It seems like it takes a while to warm up before it will run with the choke off. During this period if I take the choke off too soon it wants to back fire slightly. The whole time the bike is louder than I thought, sounds real throaty under the shifter and rear brake pedal area, I thought goldwings were quieter or am I wrong. This same area is where I here a little backfire from til its warming up. Anyone have any feedback on any of this? I have not owned a carbureted bike since the 80's, I presently own two other bikes, both fuel injected. So I may need to learn something about a big carbureted engine like in my GL1200, its an 86 if it matters any. Thanks, Oh yeah, before I bought this bike, I dont think it ran for a while.
