Rotax 912 iS

I must be missing something. Why would the top end need to be swapped?

Well maybe not swapped but probably. You would have to drill holes into your cylinder at precise angles for your injectors to go into. Probably easier to swap out your top end.

At first glance,as per the video, it looks like the dual injectors in each cylinder would make this necessary.

Talked to my dealer and they have one in an europa for testing. It uses the same ring mount and is the same size over all. Is about 10-12 pounds heavier. In their testing all is going good. No suprises and noticably smoother running. He thought the price about 25% more than a new 912s. Same radiator, and exhaust. He thought about 3-4 months before shipments would get to him. He had fielded close to 20 calls today about the engine so looks like lots of interest.

The pics I saw looked like the injectors were part of the manifold. With such short intake runs I can't see why they would do it any other way.

IMO from a marketing point of view, I don't think Rotax would make it easy to "up grade" older 912s. But on the other hand, used market 912s should be on the up swing

There's been talk around the campfire with the Rotax people I know of implementing an "exchange" program once your motor reaches TBO or is in need of overhaul. This way you get the new cases and reciprocating assembly for the updated TBO. Then you put your own carbs and ignition and exhaust, etc on the new "long block".

Haven't heard much but campfire talk on this, but the people doing the talking are on the inside...
