Threaded hole on starter damaged that holds cover

So I am going over my new to me 82 KZ750H. One thing I noticed as I was working on the exhaust is the starter cover is missing. And one of the threaded holes on the starter itself (that hold the starter cover in place) is broken. Hence probably the reason the cover is missing. Well I can find a new cover on Ebay real cheap, not worried about that.

Question is, since the cover will only be held in place by one screw, in stead of the two it should have, will it be a problem with damage getting into the starter? I can get a starter body for not too bad on Ebay, maybe even its a good idea to rebuild the starter now (even though its running fine?)

Or am I overthinking this, put the cover on with one screw and get out and ride it already?

Depends how much money you want to spend. Getting a 'new' starter motor and rebuilding it certainly wouldn't hurt anything. Alternatively this is a situation where it would be fine to improvise something, like expoxying an appropriately sized nut onto the starter where the threaded post used to be.

Yeah, you can ride it with just the one screw. It's fine.

thanks, that's a great idea. Its not going to cost anything to try and wont damage the starter body any more than it already is.

Pic? If it's the outside one, you may be able to drill it out and extract the bolt.

Its not the bolt from the cover that is broken, its the threaded shaft which is integral to the starter body. That is snapped off

You mean the long bolt that holds it together? I'd start looking for a new one before this one stops working.

He's talking about the short bore holes that hold on the chrome cover/rain shield.

I'd jerryrig something together.

I would consider using a high temp sealant to glue the starter cover in place, especially if the jerry-rigging isn't doable.
I'm not a fan of using goop to repair mistakes, but in this case it might be appropriate.
For the bolt hole you could use a short M6 bolt/nut/washer & seal it w sealant or use a nitrile or viton o-ring.

I thought of suggesting gluing it on too, but that would be a PITA whenever you needed to remove the sprocket cover. Also, messy.

However, another idea comes to mind... How about just gluing a neodymium magnet to the underside of the cover? That should hold it on, no bolts required (would have to plug those holes though).

That's a good point. I was thinking he might not have to remove the engine/sprocket cover very often, and if he applied an appropriate amount of the stuff & used masking tape to do a clean job, maybe it won't be that big of a deal. ??? The goopy idea is a last resort sort of thing, in case the thread repair doesn't work. :)

It's she and I suspect I was right all along. If it's the cover bolt on the outside, it can be drilled and extracted. If it's the one towards the middle of the engine, the carbs can be taken off, then drilled and extracted. I don't care much for jury rigging something that can be fixed right with a little effort.
