Loose drive sprocket

[mattsz]

My searches reveal that sometimes, some SOHC bikes have a loose-fitting front sprocket.  My 400's was a bit loose, and the replacement I bought is just the same - a bit of sideways wobble and the tiniest bit of rotational play on the shaft, without the "sprocket fixing plate" installed.

Assuming that's ok... when installing the new one, any lubrication or other protections recommended?

Yes, they all all slack to some degree, mines been loose since 1980.

I grease the splines to reduce wear and stop the rust like you had. ☺

Yes I noticed that but on mine once the fixing plate is done up it was solid.

Thanks guys!
