I have a 96 1100RT. These are the symptoms. When it gets warmed up it has a rapid "clanking" that seems to be coming from the transmission area. It's pretty loud and you can feel the clanks slightly in the handlebars, as well as the lower fairing right behind where your leg goes. The bike seems to run well, although when you get over 3500 rpms it feels a bit coarse, not smooth from then on up. Ah yes, I almost forgot an important point. As it sits idling and softly "clank-clank-clank-clanking..." if I pull in the clutch lever, the noise stops.
I should note that this bike has only 37,000 miles on it, and was previously owned by a guy who built his own experimental airplanes for a hobby. He had the transmission completely rebuilt by Anton Largiader and Virgina Motorrad when it had only 29,000 miles on it. It also has a new clutch disc, bolts, new diaphram clutch spring, and supposedly a dose of Kluberpaste on the splines when that work was all done.
Do all the oilheads of this vintage make this clanking sound, and I shouldn't be worried? I can not for the life of me, think what could be making this sound. And if, as I suspect, it is not normal, I also can not believe that a motorcycle with this low mileage, and with the amount of time and money that has been lavished on it, would not be running like a proverbial Swiss watch.
Thank you all for any assistance/insights.
