oregonian Posted May 18, 2022 Share Posted May 18, 2022 Is this a typical gasket leak? When riding the bike, it pops up on that location but I can't tell where it starts. Help/opinions/advice appreciated. Link to comment Share on other sites More sharing options...

oregonian Posted May 18, 2022 Author Share Posted May 18, 2022 I agree, but it reoccurs everytime I wipe it off and go for a ride. Link to comment Share on other sites More sharing options...

If so might be porous there? It is right below the clutch arm, is it leaking there? Link to comment Share on other sites More sharing options...
oregonian Posted May 18, 2022 Author Share Posted May 18, 2022 I thought it was the clutch arm also, but it isn't oily at all. It doesn't come back with the same pattern each time. Sometimes it is half an inch left, right or lower than in the photo. I can smell oil when I stop at a light. The volume of oil is very small.

peteinpa Posted May 18, 2022 Share Posted May 18, 2022 Is it blowing from a more forward leak? 2 Link to comment Share on other sites More sharing options...
Supporting Member knyte Posted May 18, 2022 Supporting Member Share Posted May 18, 2022 ...that's what I was thinking too, like the chain or something, but that's on the other side. 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...

skipperT Posted May 19, 2022 Share Posted May 19, 2022 What about above that area, from the front Master cylinder or the brake line connection? -Skip Link to comment Share on other sites More sharing options...
peteinpa Posted May 19, 2022 Share Posted May 19, 2022 If it was brake fluid when he wiped it there would be no paint. Link to comment Share on other sites More sharing options...
oregonian Posted May 19, 2022 Author Share Posted May 19, 2022 It smells very strongly of burning oil. And it looks like motor oil on a white rag. Link to comment Share on other sites More sharing options...
whisperquiet Posted May 19, 2022 Share Posted May 19, 2022 (edited) Tape a small piece of white tshirt/paper to the case…..go ride and see what happens. It looks to be an external leak falling on your case, not internal/porous casting. Edited May 19, 2022 by whisperquiet 1 Link to comment Share on other sites More sharing options...
Supporting Member piotrek Posted May 19, 2022 Supporting Member Share Posted May 19, 2022 Is this smudge always in the same spot? Link to comment Share on other sites More sharing options...
oregonian Posted May 19, 2022 Author Share Posted May 19, 2022 No - it jumps around an inch or so north/south/east/west. It takes five miles or so of riding to appear. I'm guessing it is a gasket failing, but I'd like to be able to see oil originating from a location before replacing gaskets. Link to comment Share on other sites More sharing options...
