scottoiler

[MC680x0]

I've never used one of these, and they obviously do a good job at maintaining and extending the lifespan of a chain, but, do they not cause oil to be chucked everywhere, especially if you're using engine oil?

no mate, not if it is setup correctly which is the absolute key. fitted many of these but not to a fazer and not at the slight incline you can sea above. seen incorrectly fitted nibs where the oil is not delivered correctly. it must be delivered (out of the nib) onto the leading edge sprocket, above the lower run of the chain, above the tooth that precedes the first tooth that engages in the rollers at the point closest to the centre of the sprocket. kinda hard to explain but when done correctly the oil drop is distributed around the edge of the sprocket teeth, from a 6'o'clock position anti-clockwise up to the 12'o'clock position, due to centrifugal force, and the tiny tiny slither of resulting oil around the sprocket works its way inbetween the rollers.This is all done naturally at high speeds with about 1 drop per minute being delivered. Chains / sprockets can last 25 maybe 30K. yeah yeah yeah I know some people change sprockets routinely - I dont do that and have never needed to - not when using a scottoiler. not so with lube which collects all the crap, grit and shite, and deposits it inbetween the rollers, around the seals, and around the front sprocket. Anyone who has lubed a chain for a few years and then opened the front sprocket cover will no doubt confirm  :lol

Done incorrectly, the oil just drops through the roller onto the tyre - and perhaps other places as well.  :rolleyes
