    2019 RXT 300 break in question

    I am now at 8 hrs and still only see about 7800 rpm with a SCOM and free flow exhaust. How long does break in last exactly? Could something be wrong? It isn't showing any codes or lights. Ski starts up in Sport mode like it's supposed to as well.

    It took my ski 3 hrs to open up completely and rpms were over 8k

    7800 is all mine will turn and the SCOM appears to be working. I'm running out of ideas. Even pulled the battery for a few minutes. I feel like there is something simple I am overlooking.

    Usually it's like 7760 or so.

    I have about the same RPM and 70 mph on dash without scom....10 hrs..I would think 8000+ rpms with scom. Did your speed change?

    if it was in sport mode last, will it stay in sport mode when restarted? If so, riva says the scom is good.
    Mine is at 13 hours and the best yet was 7740. I have scom only no exhaust. We’re in the same boat. Definitely by 10 hours it should be running full blast. Most say 5 hours.
    Mine is going to a performance shop I Know to see what’s wrong.
    If and when we find something I’ll let you know. Could be SC slipping at wot. Could be inconsistent pitch in prop. Was told that even a high oil level could cause it but I checked that.

    Most often than not its heat and humidity combined with elevation. Also fresh water or salt make a difference. All those contributing factors can cost you rpm and in turn speed.

    True, but I ride with 3 other RXTXs that are running 2 to 3 hundred more RPMs and about 3 mph faster than mine.

    Rev limiter is 8040, they can only have 200 rpm on you. What's your ambient temp and elevation?
