Rotax updates Evo parts
Rotax released the attached PDF a couple of days ago including details of parts updates relating to:
- Electronic timed exhaust (power) valve not working properly
- Failures of the new evo con rod
- Failures of the cable harness resulting in an unstable function of the engine
In the UK the Evo specification will only be implemented in 2016 and then only in part, but drivers racing on the continent may already have upgraded or new Evo engines.
The upgraded power valve will be sold as standard with Senior engines with the serial number 8398316 or later and the new con rod on Senior and Junior/Mini engines 8398340 or later.
There is also an improved cable harness and on/off switch that I don’t think we’ll be using in the UK in 2016.
Please talk to your Service Centre if you have any queries as they will have specific information.
