Clutch boss wear

[Redleader]

I'm in the middle of tearing down my whole engine, and inspecting things. When I took the clutch apart, I noticed a small amount of wear on the inner clutch boss (where the fingers of the steel plates grip the inner clutch). It doesn't seem like a ton of wear, but I can see it, and feel some of it when I run my finger over it. I know this can cause the clutch plates to stick and not function correctly.
Do I need to replace the clutch boss, or would it be ok for me to smooth out the marks with some fine sandpaper? I don't remember where, but I thought I heard someone say they fixed a similar issue smoothing out the wear marks with a dremel tool.
I can try to add a picture later if need be when I get home.

This is for a 75 RD350.

If it isn't too bad just fix it with a small file. If not, replace it with a chariot clutch basket for a banshee.

Thanks. I took a quick look at Chariot and was only able to find the outer basket, not the inner.
I do have some small files I can hit it with.
Out of curiosity, how much wear is too much wear?

[Striker1423]

Ohhh you want the inner basket. Ah.  Those don't usually get too worn.

[Redleader]

Ya. That's what I was thought.
I ended up hitting it with a file and a little sandpaper to clean it up. I guess I will see how it works when I put it back together.
Attached are some before and after pictures. The before picture shows the worse of the wear.
