Just got some second hand NC30 forks they seem to be in good order, i havent fitted them yet but they dont seem to have any damping in them , they seem very spring-----eeeee is there a way to check if there is any oil in them, is it an easy dumb arse job to open the top and look inside?, there are bolts at the bottom of the legs, are these drain plugs? any help would be great, i was going to put them on today but if i cant check, ill wait till winter and have them rebuilt with the rear shock!

Cheers
