    Pre-Mix Question - Rotarvy Valve Lubrication

    Hi All,

    I have a '99 XPL I purchased 2nd hand about 4 months ago now. The previous owner had converted it to Premix by removing the oil injection cable and mixxing 40:1. Since ive owned it ive never put oil in the tank and have just been reading lately about how the rotary valve lubes of it...?

    What do i need to do? Do i just put say a 1/4 tank of oil in and check it once every so often? how much oil does it use?

    Cheers,

    Chris

    There is no rotary valve on a 947 engine.

    Same thing. You have reed valve in that motor and don't need to worry about anything. Just keep mixing it or put everything back on. No big deal either way. Just have some fun with it!

    Root putting everything back on.... Come from a motor cross background so im used to mixing! Even takes the same ratio as my MX'r

    If your putting everything back on, you shouldn't mix anymore. Or just keep it the way it is and mix it. Don't do both, way to much oil.

    947 is the Rotax name for the engine. The displacement of a 947 is 951cc. Rotax used to end marine engines with a 7 so they would round up if it was not a big jump (like the 785 is called a 787, they did not want false advertising) but mostly they rounded down.
