Dropped off gas tank for derusting; modified rad fan to clear engine mount; ordered exhaust flanges/gaskets and lower radiator mount; ordered powder for calipers. After the holidays i'm gonna get with the welder and have the radiator mounts finished, rear toe brake done and the titanium header welded up.
Wow, that engine is small, imagine putting that in something like a 1981 GPZ550...!!!!
I have even bought a ZX600R 1986 NinjaR engine and all the running gear and cooling hardware. It bolts right up into a KZ/GPZ 550 frame.
Just need to find a late model mono shock 550 cheap that I can use as the donor/engineering mule.
