Spectro oil

[W.O.T.]

Since I'm new to using Spectro....do you have to pre-mix it always? I was just thinking I'd put some in my gas for the next 2 rides or so.

I like premixing, don't have to worry about under-oiling.

I just run the doo semi-synthetic because I had some left from when i had oil injection. Im premixing the semi-syn at 40:1. Seems like alot of oil buildup everywhere so Im looking for something that burns a little cleaner, or that I can mix at a higher ratio. I know alot of guys around here run one brand that they premix at 80:1 (oil manufacturer recommends 100:1) with great results.

What does doo recommend? 50:1?
Watch plugs?
adjust up or down until your comfortable?
20:1 to 80:1 BIG difference.
