If you are bored..here is some pretty good reading on the subject. Not directly related to our bikes, but some good info all the same.
I think it mainly points out that a good oil mixed to the right viscosity is key for the engines we are using. The old neighbor guy always told me that there was no such thing as too much oil, but in fact it is possible to have a 2 cycle mix to thick or to thin depending upon tollerances and the engine being used and at what conditions and ooperating temperatures it is being used at. Lots of different factors to consider for sure and enough to make my pea sized brain hurt!lol
