adj the drive chain?

My latest info is a heavy person maybe 200+ should actually set the chain around 1.5 inch deflection due to hitting say a big bump. One inch is defiantly too tight. I think my chain is too tight because its about one inch-this would cause chain wear real fast. A LITTLE LOOSE IS BETTER THAN TOO TIGHT. I think my chain should be set at 1 1/4 to 1 3/8. Put on center stand ,check in many placers for slack. Tighten pin to 54 pounds. 54 pounds might be a little much -maybe 50 pounds. 54 pounds is in the book.:tsk::suspicious::ranger::typing:

 

Holy Cow Sow! You have been holding back on us since you posted this one.
