For dirt, 80 psi is way too much. How much do you weigh? If under 200 lbs, I say no higher that 40-45 psi. This isn't a road bike, you need softer tires for better traction. Also, pump up the air shocks to your weight in p.s.i. (i.e. you weight 180, put in 180 p.s.i.). Use that as a starting point and increase/decrease by 5 p.s.i. to where you like it.
What fork is in the Jekyll 500, a Super Fatty D right? or is it the SL? Anyways, if it's the air fork, do the same with it.
