I have a Scott Oiler fitted and I do need to top it up now and then so presumably its working, and the feed nozzle is right on the chain next to the rear sprocket, but the chain never seems very 'wet'. If I leave the engine running for a few minutes there is evidence of a drop of oil forming on the nozzle.
Is this about right? To my mind, at the rate of one drop every few minutes, its not enough oil to be of any use!!
