When I purchased my 1989 1500 a few weeks ago it had some issues :X. I have worked thru most of them.When I first got the wing it was whisper quiet. My current issue started after I had to clean the "gunk out that was causing the floats to stick open. I dismantled down to below the air box to figure out what was wrong. After I put it all back together it runs just fine but I hear a lot of engine noise. It sounds like the rumble from deep in the engine. Its hard to describe - but it sounds louder and - only when twisting the throttle. When letting up the engine noise disappears. The only thing I can think of is maybe I didn't get the crankcase breather tube on the " floor" of the air-box on of well enough.It was tough to reach with the tight quarters. I really don't want to take it apart again - but what is your advice.
