Please identify this part

[Wolf Child]

Microfiche identifies it as a "Control Valve". All I know is it goes to the side of the crank case. I've never seen this before.

Yes, I AM an idiot.:burnout:

 

[tor*p*do]

crank case drain.
in theory, if you were to flood the motor, you pull the know and drain the case
never worked really good
they start to leak as the motor gets older, then the motor goes lean and can seize
needs to go. get a blockoff plate, pull motor, remove drain and install block off.
done

it's crankcase drain valve. if you got water in engine you pull khob and drain water from crankcase

Thanx Guys... No wonder I've never seen one before. :lol:

kawasaki has used it on all their 650's and 750's. DO NOT PULL THE KNOB!!

the above coments are corect, they can go bad, and leak.

i do have block off plates here for 15.00 + s&h if you want one. you do not need to pull the motor to install, but you do noeed to pull the pipe, and it is easier if you remove the starter also.

I remember when the 650SX first came out (I bought one of the first units 6 months before release) they put a little plastic baggy over the knob and held it on with a little rubberband at the base, this was just part of the packing material at the factory. Well, a lot of the dealers would leave this little baggy on when they unpacked and setup the ski and then someone would pull the knob and the rubberband would slip down under the knob and then hold the valve slightly released. This would cause a crankcase leak and lean condition and they were getting seizures. I got a call from my dealer telling me to remove the baggy and rubberband, which I had already done the day I got it.

I pulled the motor and removed the drain thingy and plugged holes with 1/8" pipe plugs (they didn't have block-off plates yet). Then sold the 650 about 6 months later when I realized how bad they sucked compared to a good mod'd 440/550.

No need for that if its sunk, just lay it over with the pipe down and plugs out.

you can also just tap the holes, and thread in a 6mm bolt ( 10mm head). seal them with lock tite, and you are good to go.

personally i would not recomend doing this with the motor assembled though. you don't want any shavings getting into the crank case area.

It needs to be tapped for 8mm not 6mm. 6mm is too small and won't work. You're right about not doing it with the motor assembled, though.

My kawi 750 still holds water even on it's side. It blows dry when turning over onm it's side, but looks like a water hose comming out of the cylinders when cranking upside down. Turn it up-side-down if you have a lot of water in it.

Sounds like a good hole to run your nitros bottle directly into the cases. :biggthumpup:

 

[750SX]

you can also make your own block off by taking the two halves of the drain apart, ripping the guts out, cutting a flat piece of metal to the size of the drain halves. Then use a piece of gasket material, cut it to size and sandwich it in between the two halves. Pretty much free if you have some stuff laying around, and some time.

it has been so long since i did it this way, i cannot remember, but 8mm sounds right.
