My 7R has gone crazy... its spitting oil and lightening

Well, I am PISSED right now. I get to work this morning and find what appears to be oil leaking from my bike. I took a chance and immediately returned home. When I make it home, I find a puddle of oil in my driveway. It was leaking before I left. I didn't notice that becuase I was preoccupied with changing my tail lamp fuse that blew when I started her up.

So now I have the left side fairing off hoping it is something simple like the drain plug coming loose. Well, my luck isn't that good. The leak is coming from somewhere behind where my clutch line bolts up. My bike has a hydraulic clutch. I'll get a pic of the area in question. In the meantime, has anyone seen a similar issue deriving from the same area?

The pics are of the same area, one was taken with the flash on. You can see the oil leaking in the brighter pic.

I think I may have found the problem. In the pic, you'll see the rod with a piston. I am thinking the piston may have failed or become dislodged. There are no gaskets, cracks, or otherwise other than that piston in the area. If I remove the rod, does it just go back in? Do I have to align it with anything? Also, is that piston suppose to be seated securely or free to move with the rod?

Yeah I can't make much out in the pics either. Are you thinking this is a simple fix?

I have a service manual but didn't need it, it was a simple fix. There's a cap in which the push rod goes through. That cap is suppose to fit snug between the engine case and the clutch rod assembly. When I removed the clutch assembly, that cap was not in place. I pushed the cap back in and now no more leak.

GM - I'll hook-up with you another time for the sprocket. I am going to stay close to home this weekend to keep an eye on it.

Did you have to replace your seal? Did you have any problems after the first incident? I guess my concern now is if I should have replaced it.

i replaced mine. The leak wasnt from the outer sealing edge, but the sealing edge around the rod.

The problem still occured. I took the bike out and rode about 10 miles before I felt the bike start too surge. I did a Michigan U and pulled into the gas station. I thought maybe I was getting low on gas. I looked down and seen drops of oil, then a very small puddle. I filled up and rode back home. On the way back, I did notice that the leak was not as bad as when this first occured Friday morning and the bike wasn't surging.

I made it home and pulled the clutch cylinder off to find the push rod seal still in place. I started the bike up but it was not leaking. My question is this, is it possible that the seal starts to fail as the engine gets hotter? Also, is it possible that the seal eventually works it way loose, as the engine temps increase, while actuating the clutch and shifting frequently? Furthermore, I assume this is not related to going to synthetic oil although this never happened last season (non-synthetic). I guess I'm concerned that replacing the seal may not fix the problem. There were no signs or indication of a problem prior to the oil leak on Friday.

JK, did your seal have a spring that went around the inside of the seal? My seal has a channel between the outer edge and inner edge (around the rod). There is a spring that goes the circumference of the channel. That spring appears to have broken and is buckled but I can't confirm without seeing another part. It would make sense that the spring be one piece as I see no other purpose otherwise. I am thinking the spring holds tention around the rod making the seal.

A seal will generally leak worse on a cold engine. It expands as it gets hot and should seal better. On the flip side, The oil gets thinner as it heats up. Making it easier for it to escape.

From the pic, That looks like a retainer clip. It may play an important role in stopping the leak.

I hope you're right. I will call the dealer this morning to check if they stock the part, otherwise I'll be ordering from ronayers. It's crazy how a $4 part can cause such a big problem.

Edit - That spring/retainer clip is in fact suppose to be entact as in not broken as seen in the pic. The dealer had only one left.

Latest Update

Good news and bad news....... So I install the new seal and ride the same route I did yesterday to see if the problem persist. I was able to ride much further than I did yesterday without incident so I am pretty confident it was the broken seal.

Oh the bad news, I HAVE ANOTHER PROBLEM . Yep, the hits just keep on coming. I am now blowing tail lamp fuses which also kills my cluster lights. So far, I've went through one on Friday and now two this evening. Fortunately, this should be an easy find. I'll look into that tomorrow.
