cb type 2 forks... couple questions for the all knowing:
#1: rebuilt/resealed. upon full compression (on the bench) both tubes stick slightly for a moment and then release. they both also make a bit of a click sound when they release as well. i know that when they are all stacked up with the springs this will(should ) go away. the internals are clean and all parts move freely with no scores on the tubes. am i just overthinking this?
#2 does the tight winding end of the spring face up?
#3 an interesting observation, should i put the top bolt/fill plug on when the tube is compressed or when it is fully pulled out? the amount of air in the tube really changes the force of compressing the fork. whats the proper way to go about this? if i had to guess i would say compressed.
what the fork!
CB forks.I would assemble the forks with the oil filled to specs and the front end elevated off of the ground. This allows you to have the forks fully extended and gives you the most air possible in the fork. I would think that the forks could possibly act as if they were locked up if you assemble them with no air or compressed. Remember that CC's and CM^3 are the same so any accurate graduated cylinder with either measure will give you the right amount of fluid in each leg.
Might also want to consider about 1/2 inch or more of preload on the springs. Not sure myself how this would be possible as the springs on my model are external but I'm kicking the idea around as I get ready to reassemble my front end. I use schedule 80 pvc for internal springs so I'm thinking this will work on external. Just add 1/2" to the length of space above the spring with no load to give 1/2" of preload. These springs are probably junk and will sag again but preloading them can offer some improvement for a while.

Re: CB forks.Just put all the parts together and add the oil and ride. ..............lm
