I just finished my 200 hour Rotax 912ULS engine inspection/service. I was really amazed at the results of the leak-down compression test. Out of an allowable 25% loss in cylinder pressure due to leakage past the rings and valves my engine tested out at 2.5 to 3.5%. This is probably better than new. I doubt whether a Lycoming or Continental would come even close to this.

If you use 80 test pressure then normal leak down is 76-78 psi. I'm still old school so I still use 87. I did a test a couple years back testing the difference between doing a test with a hot Rotax engine verses a cold engine. I tested it on 10 planes. No what the difference was on a Rotax 912, nothing. The test came out the same."It is my understanding that small cylinder bore engines such as the ROTAX 912 are best evaluated by a compression tester with an appropriately-sized* differential orifice.

In comparison to the 80 hp version of the Rotax 912 series the 100 hp product line offers more power while keeping the same weight. This engine series offers a time between overhauls of 2,000 hrs and the best power to weight ratio in its class ‒ no surprise that this engine is the best selling 4-stroke aircraft engine. . Compression ratio . I do at least 50 compression test a year on Rotax engines. Test results are usually the same, i.e. 87 over 83-85 psi is pretty normal. Normally if it loses anything it may be 1 psi more if done on a cold engine. I have seen a few engines over the years that had a low pressure test on one cyl., but usually turning it over a number of times fixes it.FOR ROTAX ENGINE TYPE 912 SERIES REF NO.: MML-912 | PART NO.: 899196 MAINTENANCE MANUAL LINE. Before starting any maintenance work, please read the Maintenance Manual completely as it contains important safety relevant information.

[3]The original 80 hp (60 kW) 912 UL engine has a capacity of 1,211 cc (73.9 cu in) and a compression ratio of 9.1:1, and is designed to work with regular automotive gasoline, with up to 10% ethanol.
I have a compression problem on my 912 uls. #4 cylinder was trending lower over a 6 month period, eventually to less than 60/80 psi, with the differential leak down test showing air rushing past the piston into the oil tank during the test, and no air escaping through either the inlet or exhaust manifolds.
