The shocks are 35 yrs old. Time to rebuild them.

If you don't want to rebuild your stock shocks

thanks for the info sir!I'm willing to do a rebuild but I'd like to put a heavier spring in the rear and front to accommodate for the extra weight,what would you recommend as far as a spring rate or brand?

You may only find the Progressive replacement springs, which are heavier capacity than the stock springs, they are listed in the parts needed in the first link above to rebuild along with the seals and bumpers needed to rebuild.
Most likely you have leaked out the oil from the seals long ago and the stock springs are weak. Less than full amount of oil in the shocks(and forks also) will give you less weight carrying capacity.

Also check to see what shocks you have as someone may have changed the shocks before now. The rebuild parts listed are for the stock Showa shocks that came on the gl1100.

I'd recommend the Progressive 416 shocks, which can be pressurized to adjust the preload. That way the preload takes up the extra weight, and the spring continues to do the job for which it was intended, without bottoming out.
