    I'm on the road heading back from Alaska. I noticed oil leaking that I strongly suspect to be the oil pressure switch (original @ 37k miles....I know, I'm kicking myself for not replacing it). I'm in Watson Lake Yukon. Its not leaking too bad but I'm wondering if it will get worse or stay same? Nearest dealer is 680 miles. I'm thinking about just sticking an M10X1 bolt in it here in the hotel parking lot instead of soldering on and adding oil. That's assuming I can source a bolt. Even if the bolt weeps its better than the leak I have.

    Opinions/experience welcome.
    Thanks

    Grab an extra quart of oil on your way to the dealer..top it off about every 150 miles, more often if it goes low before then.

    Have a great trip!

    I need to go about 1700 miles back to my truck & trailer in Yakima WA. If I keep riding its going to drive me nuts! I just checked the dipstick and is about 2/5th of the way from full to the bottom of the dip stick. I figure that leaked over about 360 miles, maybe 400.

    Mine never got any better or any worse...just kept leaking. I'm not sure how far the dipstick is off the bottom of the tank but it holds about 2.25 litres (so it's a fair bit).

    got in a similar scenario 2500K from home and I just substituted for a bolt, worked fine.
    In a pinch you can also remove the electrical end of the sensor and fill with JB weld.
    Mine was leaking profusely so had to be changed before I continued my trip.
    Good luck with it man

    I tried to get to the thing in the hotel parking lot. Took the tank off but it looked like I either need to pull the carbs/air box or a couple radiator hoses to get access? I don't have the tools for that. I ended up adding some oil and riding it to Fort Nelson. It made a mess but there is still plenty of oil in the tank. Will attempt Grande Prairie tomottow. Trying to make it to Canmore where I have a truck available.

    a rather small amount of oil will "make a mess". so, .5 L (basically half a quart) will make a REALLY wet mess. Stay on top of it at each fuel stop and keep topping it off until you can get to a area where you can get to it without causing other issues. Yes, you have to remove the carbs/airbox. I have not been able to find the automotive crossover YET....

    Just had the same go on mine somewhere in The Czech Republic on the way back home to the UK, Everything that is in the stock tool kit is there to get at the sensor, I replaced mine with a drain plug from an exc radiator that fitted

    weirdly it didnt seem to lose much oil until I stopped the motor (backpressure?)

    In my case I pulled the tanks, glove box, I moved the airbox and throttle bodies and to do this I needed to remove throttle cables (gaining necessary slack by removing from throttle tube on the bars) and unplug the large grey plug on the RHS of the frame that goes to the throttle bodies

    All in all it was a couple hours playing with the stock toolkit which continually surprises me with its efficacy

    What actually leaks on the Oil Pressure Switch? Have been searching and have not seen an explanation.:ear What kind of mileage before the oil pressure switch leaks?. My of 04 has 28,000 miles and leaked 16 oz over 10 plus hours of ride time. Sounds like it should become a preventive maintenance item.

    Hope TMoore made it back.
    Not sure why he needed to remove the tank though. If I am correct, the oil pressure switch is behind the drive sprocket. New o-ring should be all you need. Correct me if I'm wrong.

    The oil pressure switch is on the side of the front cylinder, inside the "V". It is a standard Automotive pressure switch so automotive parts place should have one (eg NAPA).

    The switch is just a bakelite switch pressed into a metal body, it leaks between the bakelite and the body. You can replace it by just removing the left side tank, but it is much easier to remove the airbox to get at it.

    Consider yourself corrected :-) that is the gearshift/neutral switch.

    Anyone tried putting liquid gasket ontop of it?

    It might work. The leak is normally slow and you should be able to get a replacement in short order, even in less developed places.

    Yeah I rode it 1500 miles back to Canmore Alberta. It leaked about
    300 ml over that time and made a pretty nasty mess. At least the
    chain stayed oiled! :D Back at home in Massachusetts now with a
    new switch installed. I pulled the airbox/carbs. I don't see how it can
    be done without doing that.

    Thanks for your help guys.

    Why not put a nice piece of Aeroquipe Line in there when you change it the first time and move it out to a easy spot to get to? As long as you turn it over just enough to spit oil before you put the switch in the response will not change..
