My first bike was a 2006 z1000, I got it with 1800mi and i babied it for 13,000mi. Recently i laid it down, only doing cosmetic damage but it was still totaled, so I got another 2006 z1000 with 15,000mi. It was owned by the wife of the dealership owner for the first 9,000mi, then by a guy that took pretty good care of it. The kicker is that its been sitting for a year. I changed the oil and put fresh gas in it, and I'm going to take it easy for a while but i have noticed the engine is more buzzy at highway speeds than my last one, and at slow speeds in a high gear (30mph 4th gear) the trans gives off some weird vibrations that my last one didn't. Is there anything to worry about, or am I just crazy?
