well today i was putting my z back together. to go to the shop and when i first got into it the chain was tight and now there is some slack on the drivers side of the chain i moved the cam to install the rockers i lost and i was going to ajust the rockers when i noticed that there was some slack now in the chain. what could cause this?

Rotating the engine backwards. Not a big deal. Rotate it forward and it will probably tighten up.

ok simple fix then thank you

Another thought - the cam tensioner is driven by oil pressure. If the engine wasn't running... the tensioner can get pushed back a bit.

When you get everything back together - start the engine and get some oil pressure - the chain should be tight.

FWIW,
