Jan,
Go to Rotax-Owner.com <http://rotax-owner.com/> and under
support/bulletins you=99ll find Engine Manuals. Find the
installation, operators and maintenance manuals and download them. In
there you=99ll find information on how to check your valve train
for entrained air and check for any damage.

Or after initial clattering, would the tappets fill within a few minutes
and the clattering disappear? The trouble is that someone else did the

Should I now undertake investigations for damage and if so, what should
I be doing to put this worry behind me? Rocker covers off and look at
valve spring caps? Check magnetic plug? Prime the oil system again to
purge air out of the tappets?
