New Cylinders for Gen 1, 2 and 3?
It looks like Rotec Aerospace is developing new cylinder assemblys for early Jabiru's. That is great news since new cylinders are no longer available. It appears the new cylinders are very similar to the Gen 4. They come with the head installed. It looks like they are testing the first on a airplane now with promising results. If Rotec can pull this off this is great news for those of us with early model Jabs!

There is one significant difference in the Gen 4 vs the Rotec cylinders for Gen 1-3. The Rotec cylinder has a steel liner, same as the OEM Gen 1-3 cylinders. The Gen 4 cylinder is all-aluminum with a Nikasil cylinder plating. Not being critical of Rotec, just saying there is a difference!
