    Fogging svho motor

    How is everyone fogging the motor? I want to fog mine but do it without spraying fogging oil through the intercooler.

    Personally, just a quick 2-3 second spray into each cylinder.

    I fog min through the cooler but otherwise direct to cylinder unless you want to take J pipe off or add a fogging port to manifold

    I was thinking of pulling the hose from the blow off valve to spray in the fogging oil

    I can't seem to find the document, but we had a tech tip from yamaha a couple of years ago.. regarding the way they suggest to fog the 1.8 liters.
    1)Stabilize fuel
    2)Run engine on the garden hose, remove breather tube. Spray Fogging oil into breather opening for 2-5 minutes( should see some smoke, or stumbling) . Note: do this with someone near the water hose or install an inline water valve to quickly shut it off.
    3) Shut off water, and then engine
    4) Remove spark plugs, or injector rail ( your choice)
    5) Spray fogging oil in cylinders---->>> Depending on the Fogging oil/lube used, this time can vary from 5-7 seconds with something thick like Deep Creep or CRC fogging oil, or 10-15 seconds with something like PB Blaster( seriously, it will work... but why on a 10k+ machine??)
    6) disconnect the cooling line running to the rectifier, spray both lines with water, and leave disconnected.
    7) Remove water box hose and siphon as much water as possible, out
    Spray RV antifreeze in water box, and the Rectifier cooling line, and fitting until you see it coming out of the intake grate/ jet drive.


    I hope that helps!
