I just purchased my first pwc. 1999 xl1200. It has a new SBT topend on it and has been swapped to premix. My question is, what is the correct ration for the premix. I've heard 32:1 and also 40:1. I will be using yamalube.

Thanks for your help.

40:1

Buy yourself a Ratio-Rite cup so you can easily do in-tank mixes with varied fuel quantities.

I spoke with SBT yesterday and they suggested 32:1. Has anybody ran this ratio and compared it to the 40:1

I have used 50:1 in my 1999 gp1200 and had no problems. But 40:1 would be safer and more lubrication for cylinder walls. I think ill use 40:1 this year.

Fuel to Oil Ratio Calculator for Two-Stroke Motors Try this page for your mixing chart to help you out. 50:1 will work fine, If going to rich on oil you will have problems if your doing alot of idling threw no wake zones, fouling plugs.
