    RPMs varying at idle?

    My RPMs are running up and down from around 1680 to 1820. Is this normal? If not, any ideas?

    Thanks in advance.

    Mine goes from about 1720 to 1820 at idle. It has done the same thing since it was stock. Franko's did the same thing if I remember correctly.

    Not changed anything fuel related. basically RIVA stage 1 setup. I just never noticed it before now. I have another fuel pump I could throw in if anyone thinks I should.
    Thanks.

    If it's supercharged, make sure the SC is OK, bearing not failing.

    did you make any changes or do any work on the ski prior to the idle problem?

    Mine does that also but more so when cold and on the trailer the rpms are more steady when in the water with a load on it.
