i removed the oil pump and tank from my 89 yamaha exciter570 and i want to know what the oil / fuel ratio should be?
i know i run 32:1 im my mx bike but not sure on a sled?
 
Right, a good oil and 50:1ish will work...

1 gal = 128 oz. 1 qt = 32 oz.
10 gal = 1280 oz

If you want 50:1, then 1280/50 = 26. You should burn 26 oz of oil per 1280 oz (10 gal) of gas.

26/32 = .8 -- 26 oz = 80% of a quart.

If you burn exactly 1 quart of oil per tank of gas, you're running 40:1 fuelil ratio. (1280/32 = 40) 40:1 is "richer" than 50:1.
