Hello and welcome
No doubt Dave or Don will be along shortly to offer you a more formal and complete welcome!
Great site, with tonnes of info, have you done a search?
As for Scotoilers, they do help prolong chain life (as they do what they need to regardless of needing a reminder!)
I know they worked (in the past) on a vacuum system, but that also meant you tended to get oil regardless of needing it. I was hoping to have gone to a show in the UK in November to see some updates, one of which was Scotoiler. They are supposed to now offer a means of being activated on the throttle position, so work more effectively with less waste and mess.
I am sure a number of other guys on here have fitted one to their bike and will give you the relevant info. I chose not to and went with some recommendations for a 'dry'wax chain lube - Wurth or Profi Dry seem to get good thumbs up.
Any photos of your bike?
