    Found this in the Sump

    I was doing a service on the bike and found alot of grit in the oil filter housing, so i decided to pull the sump off as there could only be more in there
    annndddd i found this,

    Its around 2cm long abit under 1cm wide and has tapered ends. What is it and where should it go? as it was just laying in the sump.

    You can see the sump has a round mark on the bottom of it where it looks like it has been sitting upright there, but i cant find anywhere to put it?





    any idea?

    Cheers Josh

    Locating pin, likely for the valve cover since PO's may have been in there the most often. Could also be from the clutch or stator cover.

      That's bigger than the ones on the valve cover. Most likely from the cylinder/head, but that size is used on the engine cases too. Hopefully some Suzuki monkey dropped it years ago otherwise that engine may leak or worse.

        Don't worry about it, Just save it for future use if you ever have to rebuild the engine

          It belongs in the center end of the cylinder head to cylinder.
          As it is a locating pin and an oil galley tube, thus the mention of oil leak.

            Josh, what sort of bike have you got. Any hints mate.

            It's the locating dowel between the head and the barrels, Part #04211-11189

              +1 on the locating pin.

              Josh you got the 250 right?

              I have a few of those on my 450 and I'm just at the engine reassembly point at the moment.

              There are some between the crankcases and two between the cylinders and top crankcase half which is what Don is showing you.

              The big question is... has a PO or mechanic left one out after doing cylinder work or did this somehow get in there during assembly at the factory?

              I'm not sure how to check if it's from yours other than to pull the cylinders off the crankcases...

                Bugger, I do have a SLIGHT leak where the head meets the block so to speak. How big a job is it to remove it and refit? Any machining involved? I've just got it running well too! DOH!

                Yeah its a 1983 GSX250. I think it was the GS250 in the USA.

                  Just ride it unless it ruins a pair of boots every time you ride.

                      It's not a big job to pull that head but it does take a while. It's just a lot of up and down, right side left side kind of stuff. Tear down is quick. Reassembly takes longer because of the timing, torquing in a crisscross pattern etc. It all just takes time. Get a buddy that knows what he's doing and a 12 pack of suds. Make a day of it. You take one side and he takes the other. It'll go quicker that way.

                        Honestly, if it's only a small weep and you're not constantly topping the oil up then it's a lot of work to fix.

                        Having said that, if it gets worse you'll wanna fix it, so don't lose that pin

                        Of course it's always possible the leak has nothing to do with the pin but is a sign of the gasket failing...

                          On a 250, go for it. Teardown to the base gasket wont take that long and will give you an opportunity to put fresh gaskets in. On a 4 cylinder, it's a 12-16 hour project (including new valve seals) if everything goes well. On this, it could easily be half that or less.

                            I dont let anyone touch my cars or bikes but me, i just put more care into it because i have to drive / ride it, they dont. Its not a big leak and i have never had to top the oil up at all. If it gets worse i'll replace the gaskets, hopefully by that time i'll have my Full bike licence and will be on a bigger bike!

                            Thanks for your help guys.

                              check the compression levels to rule ot a leak from the cylinder through or if its just a weep coming from the gallery. I have replaced the head gasket on my bike a couple of times. the first time i did a bad job and ruined the gasket by foolishly using the gasket sealant when i should have just made sure the surfaces were clean and bolt it down. I managed to cock it up and it ended up leaking a fine mist of oil out the left side of the head/cylinder. When i replaced the gasket unfortunately i had the through-studs snap on me when tensioning up, so had to undo everything and then wait to get a new set of 8 head studs to go along with my second "new" gasket .

                              I have a haynes manual and can scan pages & email the relevant ones to you if you like or tell you any little quirks i encountered.
