I have a silver '03 636 and my step son picked up a red '03 636 one day later, same dealer. This gives me the rare opportunity to ride two different identical bikes. I have noticed that mine does have more engine vibration than his does. I've sort of come to the conclusion that some bikes just come out of the factory with a better balanced motor. I'm not really happy about this but I don't think it is severe enough for a warranty balance. Let me know what you come up with though.
how many miles do you have on your bike? is it something that you just started noticing? i have over 2000 miles on my bike and never had any problems with vibration, yet. you may just need to go over the whole bike and snug down your bolts. did you have any of the fairings off recently? pay special attention to the headers, link pipe clamp and exhaust bracket. any loose connections there will definitley be felt through the clip-ons. i hope any of these suggetions help.
