    650 sx cooling lines help!!

    Hi I've been reading through post after post but cant seem to find the information I need.

    I've recently bought this ski. It has a pjs head. Westcoast pipe

    I've blown a hole in two rubber couplers in the last two rides. Guessing I'm not getting enough (or any) water there to keep that area cool?

    I have one inlet pipe going to the bottom side of manifold.

    Two pipes coming out of my head.

    Front pipe goes to a T which splits to a pisser and the stinger

    Rear pipe goes to the back side of the west coast pipe.

    There is another pipe coming from the front side of the westcoast pipe which goes straight to another pisser.

    I've attached photos and I hope someone can tell me if this is right or not.

    Thanks in advance.

    Welcome to the site.

    Sounds like you have standard, single cooling coming in, but you have two coming off the top of the head. The way you have it might work, but I would change to this.

    You can feed the pipe from the front outlet fitting on your head. Run a hose from here to the rear fitting on the pipe.

    Use a pipe plug to block the rear fitting on the head. With single cooling coming in, you should really only have one outlet.

    Run a hose from the front fitting on the pipe to the fitting on the stinger end of the pipe. In this hose you can put the tee to go to the pisser. You will need to cap off the second pisser as it is now not going to be used.

    I would also recommend pulling the pipe, and blow out all fittings / passageways. It is not uncommon for them to get blocked with sand, rap, etc.

    Hope this helps.

    Thanks for that. My next question would be where would I put my hose connection for flushing the engine after use?

    When flushing, you want to back flush from the head down. I would put it in the line between your head, and pipe.
