I am doing a full tear down  on the engine on my TY175 and have noticed that the gear on the clutch basket has what seems to be quite a bit of play in the direction of rotation where it rivets to the basket. This doesn't seem normal to allow this much play so I am wondering if there is a standard fix for this or am I being overly cautious?

Sounds like your rivets have worked loose, you could try to expand ( 'upset')  them, or maybe get some new rivets.

That's what I was thinking but didn't want to start pounding away on things without checking with more experienced folks.

thanks

There are rubber absorbers in there as I recall, but I could be mistaken.

The rubber dampers inside do develop play after a while. The rubbers can be replaced.

I made new rubbers and rivets about 35 years ago for one of my TY175s, thinking that the play there might be affecting on-off-on throttle work, but I could not feel any difference in the behaviour of the bike between before and after, so I have never bothered doing it on any other TY175s.

The subject comes up on these forums every few years.
