I was just on the SUPERTRAX website and saw the inquiry about an E-TEC noise when its cold. This noise may actually be generated by the TRA primary.
BRP sends out a weeky letter to its dealer network and in a recent edition it was pointed out that in very cold temperatures there could be a loud torsional resonance from the TRA clutch on E-TEC models.
The noise will be there until the rubber cushioned drive on the governor cup warms up, but will disappear thereafter. This is to be considered normal and no damage will result.
Our E-TECs are running really well and I just want to reassure the gentleman that inquired that there is no need for concern.
