 |
|
So, I just had a 300-hour overhaul done on my Rotax 503, and it's back on
the Firestar. The officially recommended break-in procedure involves
running the engine for over an hour at various RPMs according to a very
detailed routine (27 separate segments ranging from 10 seconds to 5 minutes
each, in nearly random order). I have to wonder how important it is to
follow this EXACTLY? Especially for the second half, it looks like you
could accomplish essentially the same thing by doing a few touch-and-goes
with the usual changes in throttle settings. Anyone have any informed
opinions?

Lee:
Rotax indicates this is the way to breakin the engine, primarily the
rings. The order and duration is an important part of the procedure.
If it was my engine, I would try to follow the breakin procedure to
the second.
Take care,
