Ok, revisiting an issue I had a while ago, but now with more info. 2001 v92c. After running highway speeds for about 1-1.5 hours my bike starts to cough and pop when I roll on the throttle, gets to the point that I can't even maintain speed. Idles fine, shut it off and it starts just fine, and after letting it sit for about 15 minutes I can go for another 45 minutes to an hour before it acts up again. One other thing I've noticed is a whirring noise coming from the front lower end of the bike... not sure if it's related or not. I can't pin point the location, but it's in the area where the starter and regulator is. After I kill the engine I get one last whir noise out of it afer the engine stops. So, I'm thinking that there is an electrical issue that is only arising when it gets really hot. I'm hoping someone might be able to steer me in the right direction before I take it to the Vic shop.
