Had a KZ-750 for what I though was going to be a nice "chair car". Yeah, was nice going, but always came home in a pickup truck. Usually with the output sprocket off the shaft and a $70 shaft chewed up. Major case split to replace the shaft. Took me 2 years to trade it off for a Suzi GS-1000-G. Never failed to bring me home even from a 700 mile one way trip. Didn't give me TB either. If I'd ever had the time I might have done the Iron Butt on it.
I Bought a cub cadet self propelled lawn mower 20 years back. Had a kawi engine on it. Case wasn't big enough for all the parts 3 times in 3 years. Had an extended 5 year warranty, but the dealer refused to touch it after the 3rd blowup, claimed I had run it out of oil. Nice theory, but the stick had been pulled and checked about a minute before I pulled the string and it put a rod out thru the side of the case about 10 feet of grass later. So I'm burned out on Cub Cadets, and kowasaki's.
