| Subject: | Re: Rotax 912 - interesting observation |
I have a 912ULS with 25 hrs on it. I have noticed that if the engine is warm or
has been run in the last 24 hrs the compression "bumps" are very obvious when
burbing the engine. However, if the engine has not been run for a few days it
is much easier to turn over and the compression spots are much less noticeable.
I had the Rotax 25hr check done by a Rotax Service Center but a compression check
was not done and is not specified by Rotax until the 50hr check.
Engine seems to be running OK.
Still it makes me wonder if all is well.
Jim

Hi! Jim
I don't think you have any problem.
Having stood for a period the piston rings and valve guides will have
lost the oil so you can expect compressions to be less sharp.

Thanks. I hadn't thought of that.

Mine 912uls is the same way. Super stiff when hot and looser by a bunch when cold.
I've always figured that was because all the clearances are tighter when it's
hot...
