I've searched this site, and can't find exactly what I'm looking for. I'm thinking of trading in the future to the M95 or a 1600 Marauder - used I'm sure as they are now out of production. My concern is some of the feedback I see on boards about the Kawasaki engine knocking. Now I hear that it is "normal", but a knocking engine doesn't sound good to me, coming from a car backround. Anyone have one of these bikes with the knock, and have you had any problems? I guess I could always go to a 1300 VTX, but I'd much rather have the aggressive looks of the Suzuki. Some of the Yamahas don't look too bad, but I've heard horror stories about their engineering (removing pipes to change oil, etc.). I'll probably just stick with the M50, but am intrigued by the torque of the "big boys".
