i can't seem to conquer HDtrader. when i go to email seller and send a question, it informs me to fill out all fields, which are. eh frustrating. but thanks glider, i'm guessing rubber mounted engine is better, sounds stable lol. but as far as the shaking you are referring to, is it a "gets old after awhile" or "wow i love idling" lol type shake?? i'm asking because since my coming to the descision to buy a harley, i always imagined a good nice shake. maybe i'm wrong?
