What does the manual recommend?
Or if you're like some guys on this board that are rebuild happy Probably mostly due to boredom it would seem? You know who you are, lol.I would entertain 40:1, if I were sponsored by a piston and ring manufacturer, lol.
All Amsoil 2 cycle oils are 50:1 mix (3 different ones). They even have a 100:1 mix for chainsaws and small engine 2 strokes.
I wonder how they can assure that at 50:1, for all bikes, in varied conditions and environments that this is sufficient lubrication?
Because of the film strength of the oil and the lubrication it provides in the amount of oil in that film.
I used to run MC-1 at 50:1 and never had any lube problems. I switched because it got harder to find and at 50:1 it actually was gumming up power valves.
And .... The amount of oil you run will most certainly affect the fuel mixture of the bike. The less oil you run the more fuel you have per measure of premix making the bike run richer. So a bike running 32:1 ratio will run leaner than if it were running a 50:1 ratio
Huh? 32:1 has 4 ounces of oil per gallon of gas. 50:1 has 2.56 ounces of oil per gallon of gas. Assuming the you're getting the same amount of air between the two different ratios, how can the one with more oil be leaner?
