I'm pulling my hair out (well if I had any)...My Vulcan (4900 mi.) runs sweet for about an hour and then I start to lose the clutch in city riding(moderate stop and go driving). One minute It's fine and the next stop I'm pulling a soft lever and killing the engine because I can't shift down, up or inbetween. Reservoir is full and I have no leaks that I can find. I hate to wait over a week in line at the service shop. I'm not mechanically challenged but have very little bike experience. I have a service manual but any direction I can get would be appreciated. I just started riding again after 25 years and bikes have evolved a little since the last time I wrenched on one. Thanks in advance for any help.
