kt100 chain tension

do you guys have your chains kinda on the slack side?when i got my energy kart I noticed the chain was very slack compared to my other tony kart,I was reading that to tight a chain can result in clutch/bearing problems so today i decided to loosen up the tony karts kt100 slack up some since it did actually seem very tight,do you guys set your chains on the slack side?I hope there both not too loose now how loose should it be?
I usually set mine so that on the stand there's about 3/4" to 1" up-down movement in the center of the chain... Never had any issues unless it was looser than that. And when you tighten the mount, I always do it the same way so that the resultant tightening or loosening of the chain is predictable. good luck!
