Re: Finding an oil leak

Jack I must have the weep hole's confused. I didnt realize that there were two weep holes that can be drilled.

So how does one go about drilling the weep hole and location of said hole.

Re: Finding an oil leak

have you drilled a drain hole in the clutch housing yet? Several have done this and it will let you know if you have a main seal leak without disassembling the bike.

Re: Finding an oil leak Take Two

Well the leak is back!

What are the symptoms for the rear main seal? Someone mentioned the clutch slipping and going bad. (not having that problem)

If I have to go into the rear of the engine, I plan to change the clutch anyway, so I may run it for awhile to see where this takes me.

Any suggestions?

Re: Finding an oil leak

The rest was probably windblown fluids..

Re: Finding an oil leak

Now I am confused! I rode over to a friends house, for him to help me find the leak, When I arrived there was oil on the oil pan, the bellhousing, centerstand,
and a few drops on the ground. I found out he was busy so I returned home. I took the longway home! The "BeerBurner" is running like a sewing machine. I arrived home and NO OIL LEAK!

I will keep an eye on it. I figure somehow I overfilled the crankcase. I changed oil in Utah, before returning home, the leak started on my ride home.
I am still scratching my head.

I replaced the crankcase vent line, did a canisterectomy, and have a few more things to do. I found a fork tube leaking, and need to change the front abs sensor.

That's the way I have read about finding an oil leak. It makes it a lot easier to see where it is coming from.

Re: Finding an oil leak

Thanks Deacon Channing. I will be so glad when the O-rings arrive to get on with this job. We are having some of the best riding weather right now.

Re: Finding an oil leak

ouch.. I'd check where the skid plate supports bolt up.. and hope it didn't crack anything...


the "best" way is to CLEAN 'er up... yes.... I know.. but if it's clean it's easier to spot the track.

Look for the "wet" area around bolts, sensors, etc.

One place things tend to leak is around the cam/valve cover after a valve check... might be as simple as that... and it would NOT show until you had the motor pretty warm and the oil spinning real good.

Re: Finding an oil leak

Thanks for the responses! I am waiting for the O-Rings for the injectors.

I have not started looking for the oil leak on the underside yet. I started with the crankcase vent line, it had a small crack, and a small leak. Not the problem though.

I remember crossing a "SPEEDBUMP" from hell and dragging the skid plate. I am not sure if that is the problem or not.

I am hoping that it is not the main seal! I understand that it is a rough job.

Re: Finding an oil leak

I guess you cleaned up the bike really well after the Injector seals were replaced... could some residual of that be making it's way down?

What about the oil pan.. is it wet toward the stern or bow?

Have you verified the "snugness" of the oil filter cover? (hoping for a NON-serious resolution)

Re: Finding an oil leak

If it is enging oil, you either didn't clean up good enough after your last oil change, or you have a main seal leak that will eventually destroy your clutch. I hope its the first option, otherwise you're looking at a $2k fix (or a very involved maintenance session).

Finding an oil leak

Any tips by the guru's here? I have an oil leak, there are wet spots on the oil pan, a couple of drops on the "Bell housing" and a pond on the skid plate. It appears to be the oil pan, but it does not drip while sitting, even with engine running. It appears that it is leaking when the bike is moving.

Do I need to add pic's?
