    What should stock RPM be running?

    My 05 RXP the max i can get it up too is 7850! Is this about right? Also I have a little bit of white smoke coming out of the back when its idling or going slow 5-10mph is this normal to see?

    you should be seeing 8000-8100 RPM's. Having the engine over filled with oil will scrub off RPM's. I bet you are overfilled as you are smoking

    yea, not all skis see the same RPM's due to varrying circumstances. Ideally the higher the better

    Well I just past the 10 hr mark and had it at WOT for about 15 sec and only reached 7850 rpm. By the way it has smoke just a little since I have brought my machine 3 weeks ago!

    Any body else running 7800-8000 rpm range stock or is it just me!
    It was also 86 degrees today

    RPM's

    My 05 RXP is only turning 7850. Once in while for a split second I see 7900. I basically have a PPG stage 1 setup. I will need to have my impeller repitched. That should get me back up. But I also saw 7850 when the ski was all stock. I am really believeing that the dealer overfilled the oil a little. I just did my oil change and have not been on the water. I will see this weekend.

    In the Dallas area in the summer, 7850 was a fairly usual number for the RXPs I've seen. In the cooler air it gets up to 8000-8100.

    Mine does about 7800 to 7950 depending on weather conditions! I did notice a loss of power and speed last sunday when temp. hit 100 deg. So seems it will vary with altitude and weather cond. big

    I saw 8050 after 10 hours before any mods. Now I've only seen 7950 max (most in the pitch).
