    "bit of an update,
    took off vst clean out the filter today after reading some posts it seemed the same prob i was having went out to try but its still the same,
    can anyone tell me about the little valve on top of the vst if i press should fuel or air come out iv pressed it and noting happens its the valve like on a car tyre,
    other than that could it be anything to do with me changing the impeller that i did the other day.
    thanks"

    Default "sounds like you need to pull

    "sounds like you need to pull your injectors, and soak them in yamaha quality care carb cleaner for about 6 hrs then blow them out with carb cleaner in a bottle, im willing to bet the motor will run better then it has in a while, you can get the yam quality care cleaner at any bike shop that sells yamaha bikes or jet skies, its about 11.00 for a qt bottle and you mix it 2 parts water to 1 pt cleaner, you can get about 20 cleaning jobs out of one bottle, dont get it at the marina they will charge you 50.00 for it, one last thing, if your not running one you need to get an in line 10 micron fuel filter"
