Motorcycle Repair: CB160 Front shock removal, honda cb160, cmsnl

Question
I'm have a heck of a time getting the front shocks and forks off a 1966 CB160.  I'm using a Glenn's repair maunual and have removed the two top fork retaining bolts and the two 10mm bolts from the lower bridge.  How much force should I use?  Is there a trick I'm missing here?

Answer
Charlie, there are two versions of the forks.

for the forks. Even though they only show one style there are references to earlier versions which had steel fork sliders (painted the same color as the bike) vs alloy, silver painted ones.

Flood the bottom fork stem with penetrating oil, lightly insert a flat bladed screwdriver in the slotted area and tap gently to wedge the screwdriver into the slot, which will expand the grip on the fork tubes.
Put the top fork bolts back in a few threads, use a wooden block on top of the fork nut and hit it with a hammer to get it started downwards. Once it moves, continue to keep lubrication on the joints and twist, turn and pull the forks down out of the fork stem/bridge.
