Hi Grail. Welcome. I ride with HD and HD-clone riders all the time and always get compliments about the Speedmaster. Of course, I have to listen to the stories about how they had a Bonneville back in 1968 or some such. As far as mechancial wierdness, I have almost 8500 miles on mine in 10 months and have had to lube the chain and change the oil. It is about time to synchronize the carbs though. I've started noticing a bit more vibration through the lower rpms up to about 4,000. Oh, I have had to replace the rubber carb vacuum caps a couple times. I keep extras in the saddlebags just in case.

Good luck,
Richard
