"Rattles" and "Spins" when I push the Start Button

Re: 1981 KZ 750 LTD

About a year ago I pulled out the starter clutch and replaced springs, caps and rollers

The problem was: when I hit the start button I'd hear a rattling sound (like shaking a metal coffee can with gravel inside) followed by a metallic "spinning" sound

When the spin would stop, I'd hit it again. Occasionally it'd crank briefly, but inevitably the rattle would happen, again followed by the spin

Replacing the springs, caps and rollers was just what was needed. Worked beautifully - for about 6 months - and then it started again.

It's bad now and needs to be fixed again.

Question: what causes a starter clutch to go bad?

Sounde like it is worn out.
Replacement of the complete unit might be an option.

Could it be that the bolts that hold the 1 way clutch to the flywheel have come loose? There is a diagram at Kawasaki for the previous year, but not the 81. Are they the same/ similar?

Edit: see the next posts diagram, patton beat me to it.
#120 x3 where they go into 13194

Thanks, patton

Good Fortune!

I think this time,rather than trying to repair the old starter clutch (after all - it is damn near 30 years old!) I'll replace the whole thing

Thanks, guys

Problem is he will probably have to replace it with another 30 year old clutch....:laugh:
