The ONE wants civility so maybe we can get back to technical questions for
the RV10. How and how often are the injectors being cleaned? I would rather
not find a clogged or intermittent injector on takeoff.

Don't know how often, guess as often as you care to dismantle thing. Soak in gun cleaner.

Dave, I don't see any need to mess with the injectors on my Mooney
more than every 200 hours or so. If you still have the same mixture
spread leaning from rich of peak to lean of peak that you had after
last cleaning, they are fine. You can easily tell from EGT traces if
an injector begins to behave a bit differently. The injector lines
will only tolerate so much bending when injectors are removed and
replaced, and frequent disassembly doesn't do the threads in the
cylinder heads or spyder any good either. I'd go on condition based on
EGT results.

FWIW.

An interesting forum discussion by Mike Busch recently talked about this as part of scheduled maintenance.

Mike's input was that it is an un-necessary expense (with the risk of damaging the injector insert or threads) unless there is an indication of poor performing cylinder.

I have cleaned mine once in 4 years, and when I did pull them, they were all clean anyway........I did not pull mine this year.

do not archive
