Original OEM oil from 1986 (whats left of it) in forks. Needs seals. Is it OK to loosen any nuts for drain and fill before taking the forks off ? I do not have a bench with a vice. Only hand held vice grips and I do not want to murder it. None of the nuts have ever been wrenched and I don't want to be the first to strip them because I am good at doing that. Got the bike from original owner.
