Oil leak

[Rafterd]

Ok what am I missing? Clutch slave cylinder needs rebuilding. Removed gear cover to get to the slave cylinder, rebuilt slave cylinder, reinstalled it. Blead the clutch system, clutch is great. Need to reinstall the gear cover, broke the gasket.

no big deal, just a dab of silicon gasket sealer on each break, installed cover, being sure to install the copper washer on bottom bolt. Got it together, test drive. All is good. Pick up my tools and look at the bike, oil leak on left side. Crap. Not bad, but didn't leak at all before. Put back on the lift, pulled cover, cleaned all the silicone off, look everything over and don't see anything wrong. Added silicone again, made sure I didn't miss anything, put it all back. Test drive. Still leaks.

Im leaving for Sturgis in a few days, so I order a new gasket and the copper washer to install when I get back. Put bike back on lift and removed cover. Cleaned all the old gasket off both sides. Everything looks great. Installed new gasket, copper washer, put together, test drive. STILL LEAKS!!!!! WTF did I miss??

Did you get this resolved? Reason I ask, I am soon to replace or rebuild my clutch slave and wondering why it was leaking.

[Rafterd]

No I have not. Removed cover again, put it on the lift so I can see everything, can't see any reason. But it still leaks.

Gonna take it off again, add gasket sealer to both sides of the gasket, and the copper washer, and try again.

Did you read the directions for the application of the silicone gasket sealer?

 

I used silicon gasket maker or whatever it is called when I reinstalled the differential cover on my truck and it leaked. Turns out it was supposed to be left to cure for 24 hours before reinstalling. Ford used silicone in lieu of a gasket at the factory but I use a gasket now and they are available at the parts houses so I suspect many people agree with me.

I haven't used the silicone yet and not sure I will. But just about out of ideas. I've been using it for over 50 years, don't like to, but sometimes you gotta do what you gotta do.

UPDATE.... Ok I found the oil leak. It wasn't the cover or gasket after all. Like my dad used to say, keep your head out of your ass while working on these things. On the bottom of the engine, next to the oil pan, the hydraulic clutch line has a bracket that is bolted to the oil pan to hold the line so it doesn't vibrate and break. You have to remove that clamp to gain enough slack in the line to remove the slave cylinder. I forgot to put the bolt back. Well I guess my dad was right.😀

As I got older my dad got so much smarter. When I was a teen ager he was the dumbest guy, he just didn't't understand anything. Before he passed away, I thought he was smarter than Hawking and Einstein together. Maybe one day my kids will feel the same way.

Sounds like you have been to the YamahaLarry school of mechanics.
