I thought I'd check the barrel's out today as I had the pipes off and when shining the torch up there I noticed that the front cylinder RC valve is half open whilst the rear cylinder is fully open (fully recessed). The strange thing is that both RC valve pulleys are lined up with the indicator on the pulley back plate...how do I adjust them so that they are both fully open with the pulleys lined up?

Also, how smoothly/freely should the RC valve pulleys operate? Should they take a little force to move or should they spin easy?

Cheers
