Don: If you have a 912 UL, A, or F, the compression ratio is 9.0:1. On a 912 ULS, or S it is 10.5:1. This is stated in the Rotax Engine Operators Manual. Call your Rotax Dealer and give them the S/N of your engine which is located on top of the right side of the engine (when facing the propeller), near the magneto end to confirm it.
