A 1994 polaris 750 sl isn't premix it's oil injected nothing to worry about other than injectors.
Many Polaris 2-stroke motors have an oil injection system that varies the amount of oil required. If a user is eliminating this system, or has a unit without oil injection, the standard ratio is 50:1.

The compression ratio for a 1994 Pontiac Transport, according to the Owner's Manual is 8:5:1.
If you call a GM dealer and give them the VIN# they can tell you what gear ratio you have.
This would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic). My 2 stroke I have is a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems. Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
ideally, 13.7-1
50:1
