No point thinking about engine rebuilds until you know how long the trap and air filter box hasn't been cleaned for. Mine filled with oil vapour quite quickly due to internal damage the engine had sustained previously causing raised crank pressure. Give it all a good clean out, fit new foam (make your own out of akitchen foam scratchy thingy) and air filter,ride it and observe. Even if there is nothing particularly wrong with your engine, its an old engine so internal wear is to be expected but oil vapour doesn't give conclusive evidence that there is a problem that needs immediate attention. As has already been pointed out a combination of oil vapour and blue smoke would give more of an indication that there may be a problem.

You could sell that as an unused gift
Julie - that's much thicker than my original disintegrating one - any reason for that? Or for keeping the scratchy bit?

Or for keeping the scratchy bit?I don't use the scratchy bit, i just cut a slice off of the bottom of the sponge, the same depth and size as the space under the panching plate . Does the job a treat.
Ok, so I thought I'd remove the front wheel so I could squeeze the caliper piston out with the brake lever before dismantling. Let's see, step one: "remove the speedometer set screw." Easy enough. Hmm, the recess looks pretty small, what size allen wrench is that? None of mine fit. Wait, where's my damn glasses, that doesn't look quite right: (Attachment Link) Wha? Quick forum search for that set screw... oh. So this is how it's going to be, huh? (sighs...)
