78' kz1000 with fresh 1075 kit. Starter sounds like it turns but doesnt spin the engine. Took off the left engine cover to check starter clutch and seems to work fine. Then I may have messed up, tried to push start it. Put it in 3rd and popped the clutch and all kinds of evil noises came out, engine turned but was obviously not happy. done messing tonight but was gonna pull the head off tomorrow and have a peek. How would it act if I spun the crankshaft? Making around 130hp at rear wheel and never welded the crank. Only have 408 miles on this rebuild and almost $5000 to get it done.

i dont think you could have spun the crank just by push starting it, but those old kawasaki's loved to spin the crank (suzukis too i beleive) and you should have had it welded....if for some reason you have to tear into it and you plan on keeping it id weld it up...just my .02
