Well, I'm using a basic three-step method which is more time consuming but cheaper than spray lube. First a liberal but not excessively generous working in of generic 2-stroke oil, working it in, then a good coating of grease, again worked in, followed by a final generous spray of switch cleaning solvent. Finally the vehicle is parked in the sun on a strip of foil to encourage it to melt in properly. OK, so this is a totally pointless waste of time and no it's not an 'O'-ring assembly. But anyone wishing to compare chain life and having the resources (2 pretty closely matched bikes, for example) is welcome to try it. G DAEB COPYRIGHT (C) 2008 SIPSTON --
