WTBorrow:Vacc gauges/manifold

Ok boys and girls. Recently cleaned a set of carbs on a buddy’s Katana. Well I have them pretty well syncronised by ear (oldschool baller method) but Id like to sync them with a set of vacum gauges just to make sure they are up to snuff. Anyway does anyone have a vac manifold or a set of vacum gauges I can borrow? With all of the NYSpeed thievery going on I wouldnt mind droping a security deposit or whatever so the owner can sleep soundly. Id also be willing to throw a few bucks the owners way for letting me borrow them. Thanks in advance.
