  • Help Oil Leak!!

    Hey guys! So I just bought a 03 Roadstar 1600 which I absolutely love, it runs like a champ! So first thing I done when I got it was clean it from top to bottom. Well today me and the wife went on about a 3 hour ride and when I got back I noticed brown oil marks in between the heads. Is this possibly a gasket worn out?

              You should still check to see if the hose is there or has been properly plugged. Looks like old oil to me. Also, have you changed the oil since you bought it? It may have been over filled. There are two drain plugs. Add only four quarts.

                Oil leaks are very rare on the Roadstar. Looking at the pics, it almost looks like someone had the cylinders off and put some kind of gasket sealing goop on the cylinder base gaskets.

                Looks like dried up gas to me. Carb vent conneted to intake? Possible carb puke after a run.

                  I agree with JC. Looks like dried gas to me as well.

                      A new bowl gasket should take care of that.

                    I agree with Father Pobasturd on this one. The cylinders should have regular gaskets and by the looks of your pictures it appears the previous owner used liquid gasket on the cylinders when putting them back together. The only time liquid gasket should be used on the engine is for putting the case back together when you split it. Hopefully this isn't the issue but it is possible. Try cleaning the area and then riding the bike just long enough to pin point the leak.

                      Still looks like dried gas to me.

                      Yeah that's fair. It looks very golden brown rather than the darker black you would get with engine oil. Would this color come from fresh oil though? Spydr

                    Clean theshit out of it with a stiff bristle brush and brake cleaner and the clean whole motor...sides top bottom underside with full strength degreaser (simple green) let it sit on there 10 minutes and wash/rub and rinse thorougjly and dry with compressed air. Then go for a long rude and park it and loo at it the next day. If you don't do it thus thoroughly you may find one leak but not others.

                      Different oil leak . I developed a kind of weeping oil leak at what looks like the right rear corner of my rear Cylinder Head Cover. Is this a "normal " thing to happen running in 100 degree weather ? Can I simply Tighten up the bolts around this leak area ?

                        I would try to torque the bolts but use a tq wrench. those will easily strip if you put a bear paw on them.

                          Well Dave that was a bust . Kept right on leaking , then I was able to get my head out of that dark spot and realized the leak was further back and down some . New O ring in the upper oil feed line and all is good in Roadstar Land once more .

                        Thanks Dave

                          I wonder how an O ring behind a flat flange against a flat mount surface could "wear out ? " and leak ? That's what happened to my upper oil feed line on my '01 Midnight . I mean HECK ! it hadn't leaked for 107,000 miles . How is this possible ?

                            I had to replace those orings on the eagles bike to correct an oil leak on the lower side.

                            Got all 4 coming . Will renew them all for another 107,000 !!!

                          Wouldn’t hurt to check all the hoses in the general area. The oil tank has a vent hose that’s prone to crack and leak, as well.

                            Started to pull oil tubes and noticed upper bolt on bottom end of return tube has no bolt . Looks like a blank stud. What the heck ??

                              that is they way it is supposed to be. Kinda odd but correct.
