time to fix that oil leak

here is where I think its leaking from, this pic is the front of the front cylinder and the leak is coming out of that little hole under the first word. couldnt figure out how to circle it, only put in text.



is this what I need to remove and does the spark plug need to come out. I know the pic is the rear cylinder but I only have pics of this side of the bike.



I'm just throwing this pic in because I'm pretty happy with how an old 86 with 30,000 miles on her cleaned up after a backyard stator change, and she looks so much better than the previous two pics!

cindy!!!! is this where we discussed my oil leak was a while ago, right below the t in the word this in the dissassembled bike pic. and do I just remove the spark plug and use my rear wheel nut to remove this to replace the oring, thanks! I dont have photoshop so I had no way to circle it. and I know it would be the one on the front cylinder, I just had no pics of that side of the bike.

That is where my oil leak was from & yes it is the drail hole for the sparkplug & it was an o-ring that fixes it. I didn't know about the rear nut trick though! I bought a slightly larger SAE nut and ground it to fit. Sounds like a good tip.

The whole sparkplug "well" cones out. That's where the (new to me) rear tire nut trick comes into play. That nut or one sizably similar fits into the nut shape at the top/opening of the well. It's threadded in. Simply remove the spark plug, remove the sparkplug well, rplace the o-rings & re assemble. It really is a Very easy repair.

Here's the explode. Of course it's from the opposite angle! It does show where the orings are.

I'll confirm crobins tip. I think the nut to the rear axle was made to remove the spark plug cylinder! it fit perfectly. and took 5 minutes to repair the o-rings. I'll let you know if its done leaking!

Be alittle pacient with it. Thee will still be some oil left in there unless you cleaned it out real good. It did the trick for me.
