How much chain slack do I need

[WelderDave]

Just as the title indicates, was wondering how much slack I should have in the chain while the bike is on the center stand?

I didn't really check it with a measuring instrument or anything, just pulled on it before taking the rear tire off the first time a while ago. I adjusted it close to what it was before hand by memory before actually riding it for the first time. Everything seems ok, but it seems like I may have to much slack in the chain.

When I adjusted it, I had a rough number of 2" of slack from a long time ago from some bike I was working on at the time, but I think I may have about that, maybe 1.5" of slack. Can anyone confirm 1.5" or what the measurement should be?

I always check the chain while on the ground and me sitting on it. Slack should be 3/4" at it's tightest point on the lower run in the middle. The chain should also be wiped clean and lubed every 200 miles and check adjustment.
