    Directions to convert 1100 to premix?

    Just bought a '98 1110stx and noticed the cables to the premix pump are broken. Want to just go to premix. I cant find directions to do this anywhere. What do I need to do? Just pull the pump? disconnect hoses? plug nipples on carbs? not really sure whats best practice. HELP, I wanna ride this thing Saturday!!
    thanks guys!

    Put oil in the fuel tank and run it a few minutes to make sure the oil is distributed throughout the system.

    Remove the pump, install a cover plate to keep dirt & water out. Remove the hoses and plug the nipples on the carbs.

    Thanks Steve, I did ended up doing just that, I just wanted to be sure. Did you cut and paste those directions from YamahaJetboaters.com?

    No, that would take too long. Actually, I'd fix the cable and run the injection system if it were mine.

    While you're working on that, pull one of the water hoses off the front cover (under the oil pump) and gently blow through it. I've found a couple that were completely plugged with dirt. Those hoses supply cooling to the stator.

    See ya on the other side!
