I'm looking at a bike on the weekend, private sale. So before I go out there I want to do a revs check to ensure that it isn't encumbered or that it isn't a repaired write off. Now the bike is about an hour from me, so if I like the bike I'll probably leave a deposit. My question is if I do the revs check, then go to inspect the bike, put a deposit. Do I need to do another revs check before I pick the bike up a week later?
