I have two places it seems on my 02' x1 that I'm getting oil leaks. Any ideas what may be causing this or how to fix this? One spot it seems at the base of the rear cylinder and the other is the right side of the rear cylinder around the base of the pushrods.


Rear Cylinder Pushrods
Right side of cylinder
Rear cylinder Left side

Thanks for the help

You need to clean that area and spray it with aerosol deodorant. Clean it. Spray it. Run it. Then you can tell exactly where it is coming from.
Is there any oil coming from your air cleaner? Looks like you need to reset the date on your camera...

Other than that, what Pammy said! : ] That darn oil can manage migrate all over the place in the presence of wind, vibration, and gravity and such.

I believe that I read somewhere that base gasket leaks are often caused by improper warm-up before taking off. Don't remember where I saw it though.

What kind of pushrod tubes are those?
Not that they're causing the leak, just never seen any like them...

Well I cleaned it with the deodorant (suave to be exact) and it seems as if the oil is leaking from the places I drew the arrows. There wasn't anything on the other side of the cylinder. Any thoughts?

Never seen black pushrod covers, only seen chrome ones, I was going to have a pair blacked out with powder coat, that's why I was asking. If these came standard on any M2 I certainly never noticed them being black before.

But them bases look leaky...

Do you think maybe the seals under the covers are bad? Can they be replaced without removing the top end?

black pushrod covers

DonĀ“t know when they changed to black,but as you can see on this promo picture they did.This one is a 2001 model.
P/n for the black ones is 17977-01Y
So it is self-evident because of the p/n they did in 2001.

You got to remove the rocker boxes.
No big deal.

When removing/installing those screws, what is the best tool to use. Their to close to the tubes for my sockets to fit and I would think I would just strip it with an Allen wrench and wouldn't be able to torque it when installing. Any recommendations?

I appear to have the same problem, I have 32K on my bike. I originally thought I had a leak at the base of the rear cylinder as viewed from primary side. I now find that as you show in the photos that the front tube of the rear cylinder has a leak.

Was the leak at the tube the culprit? Confirm if just replacing seal and o-rings solved the problem.

Any recommendations or advice/shortcuts to make easier.

Thanks

I ended up leaving it alone, but it was leaking from both the base of the rear cylinder and pushrods. It wasn't bad enough to leave drips or puddles so I just folded up a paper towel and put it underneath the starter. I sold the bike a couple months ago but the paper towel thing worked fine when I had it.

Zippers(you can get them from any vendor) make a pushrod tube/base kit that are less likely to leak. The o'rings are a bear to install without rolling(everything has to be clean and dry)or pinching. That's what we use. Works great.

Bikers Choice also has a set for about 130. the kit comes with all the o'rings, tubes and bases.

That's about as easy this job gets.

Here's a better way:



American Sport Bike carries them I believe. A lot cheaper than the Zippers and less chances for leaks with the stock 1-piece tubes.

Is the base gasket leak a typical Buell problem? Obviously this is a big job to repair. If you have to pull rocker box to fix tubes I guess that it is not that much more to pull cylinder. Wonder what the cost to do this is?

The American Sportbike part looks like a good solution for tubes.
