35mm Ceriani Question

Ok, so I see you should use a heavy fork oil in the 35mm Ceriani's however curious about set up. It is stated they take 170cc oil. My question is, with this heavy oil do you stick rigidly to this or will using the air gap method provide a better outcome?
I know it will mean a fair bit more?
Thanks in advance.
 
Never did anything other than run 170cc in mine and they were always excellent. Can't remember weights but pretty sure 10 or 15 is fine. But then, I'd never heard of an air gap back then! The venting caps might mean the air gap method won't work?

They are a fairly trouble free item. Unless you fill the forks to the brim, as I discovered on an SF1 with a GT front end that had no travel!!!  :o :o :o Seriously, some fukken people should just NEVER touch their moto!
 
170 will have the valve just covered at full extension and damping is covered over full travel. Air gap effects springing as it reduces volume of air compressed in addition to the metal spring.

So if your spring rate and preload are good, then adding oil is just adding unsprung weight?  :D

Not necessarily.

Fork travel can be limited and a good degree of spring progression achieved.

I have been experimenting with fork oil level lately. I went from 130mm to 160mm of 20wt in the Cer 38mm forks on my 3C and was very surprised to detect NO CHANGE in travel action or anything else even under hard braking on our typical crap roads. It was only one ride so not definitive. I also did the same on my Pantah only with 15wt in its 38mm Maz, I did detect a change but far from dramatic.Same travel used at 80mm, well less than its pertensal 130mm but at least it was more compliant with less oil. So all this talk about 5 and 10mm difference in height being detectable as 30mm bearly causes a change, doesn't appear to happen on my bikes.
