I would say the the electronic powervalve will still need to be cleaned, just like the regular one. It will get gunked up in the same spots, instead of being adjusted/forced down by the spring, it’s controlled pneumatically by a solenoid with two modes to select from.
The ignitions have different curves, jr for example is getting 2000 more RPM on the top than before.

Everything i’ve seen so far shows the “testarossa” kits having the potential to be measurably faster than their existing siblings. That by itself is a good thing, but how are Rotax are going to handle the transition……
