912is differences in Model year 2014-2018?

[tracstarr]

Wondering if there are any differences in engines over the last few years. Specifically, a 2014 model year vs 2018?

the first 912iS engines displayed low torque so a free kit was offered about 2012 which replaced the air box and ignition coils. So some of the old ones may still be around. Then the alternator regulators were changed due to a mandatory service instruction and later the alternator stator assy was changed.
Check Rotax documentation for all changes to the engine.
