Hi everybody,
I just bought a 2000 Cyclone and took out for a little ride. This morning when I went to check things out there was a little pool of oil. I tracked the leakage to a piece of tubing that looks like it has actually been cut but is only dripping very slowly, when the engine is running, only air is coming out. Anyway, I've ordered the service manual but would love to be able to ride before then. Since I'm new to doing my own maintenance I would love to know what I need to do to fix this issue. I'll attach the pictures in a link at the end which shows the puddle, where the tube attaches and how it looks now.
Thanks a ton!

The hose is for crank case venting. Some install a catch can, others just let it drain, and some install a filter and a drain valve. look up catch can or crank case breather there is a ton of info out there.
That puddle looks like a whole lot of oil. You should'nt have that much drainage from a ride unless the oil is overfilled and it has no place else to go. Actually it looks like cat puke.

What you are seeing in the photo is water mixed with oil. That is why the color is white.

Nothing to worry about. I have two tubers, both X1's and after a spirited ride, have that problem too.

By the way, welcome to BadWeb

American Sport Bike sells breather catch cans that are efficient and stylish. Check them out for your solution to a cleaner garage.

Nice bike. I loved my M2.

That tube is overkill... you can get along with a smaller one. After fusing a lot and leaving oil spots everywhere, I wish I had just rerouted mine back into the intake (which many people here think is heresy). It keeps things from being a mess, and I don't think there is enough spooge to matter in terms of performance or longevity (but know people smarter than I disagree).

You might want to pop off that forcewinder, and make sure it has a grove on the inside and the gasket in the right place with the right hole to let a tiny little vent on the carb mounting surface vent. Some forcewinders of that vintage had it covered, or people put the wrong gasket on and plug it. The bike will run that way, but not as well as it could.

Make sure your front exhaust is an upside Y shaped piece as well. That will save you grief with broken header studs.

And run your belt scary loose. Sit on the bike on the side stand, reach down, and make sure you can deflect the belt enough that it is just touching the swingarm when under tension. Better loose than tight.

Also when you get the chance, unless you know it was done already, you will want to pull the primary cover and make sure the tensioner in there is the newer style shoe (with the thicker backplate). Replace the primary cover gasket with the newer metal style.

At 10k miles, drop the oil pump and check the pinion gear on the crank for wear. Make sure you rotate the engine to inspect both sides of it. If it's worn, replace it with the new gold colored "race" part for the XB's. If not, bolt it up and ride. It's a tolerance stack issue with the oil pump, so not all bikes eat 'em.

Enjoy! Great bike.

Thank you all so much. I'll get right on those recommendations. I wish I could repay you guys.

Stroll on over to the Knowledge Vault and spend some time browsing around. You'll spend more time than you wanted to and learn more than you need to know. Oh, congrats on the bike and welcome to the Badweb!

Geesh. Typed that too late last night. It sounds half coherent.

The Y shaped thing is the front exhaust hanger. Most bikes got upgraded by now, but if yours didn't, that saves a lot of misery drilling out a broken header stud.

Which has a link to here:

Some good discussion there as well, that maybe the old system would work as well or better if it was all pinned down good and tight. That's certianly the direction they went on the XB later, and those exhausts are less problematic (but will still bite you if you let them).

The forcewinder thing can be found here (and several other places):

Regarding the oil drip puddle: Problem? That ain't a problem, that's a "feature". Ha ha.
Somebody put a Mikuni on your bike, but routed the crankcase vent like that?
Catch bottles can be hidden, the crankcase vent tubes can go any direction, even straight up, and still work (proven) so there are many ways to keep drips off the ground. I have an REI nalgene bottle ($1.79) hidden under the seat base plastic. Doesn't take much. Many, many, different ("creative") solutions, people use beer cans, or other catch containers of personal significance or symbolism and don't hide them. Or a billet one for $100; all good.

Not to take business from Al, (I will be getting on of his XB containers that mount back of the oil filter, those are sweet)... Pegasus Auto Racing sells a very inexpensive catch container that's pretty much perfect for $20 that many of us have used for the breather catch can.

https://www.pegasusautoracing.com/productdetails.a sp?RecID=4703

There was a guy painting the buell pegasus on them and selling them for a lot more money a few years ago.

Like Reep suggests, I kept my air line routed into my stock airbox for years, but eventually the crud ran down and caused the foam gasket to turn to nasty black goo.

Many of us have opted to route the breathers out the top of the rocker boxes (XB upper Rocker box covers) and plug the breather bolt holes by using solid bolts to secure the carb mount bracket. Some have found the XB covers to reduce spewage entirely... I still need a catch container to keep the spew off my bike and/or garage floor.

Blake has posted about removing the umbrella valve and drilling the drain hole out a little to improve downward flow so you don't have as much oil puddling up in the top of the motor, you'll need to look a few years back into the K.V. to find that one, but it's another option for reducing the goo puddling issue.

Remember to only check oil after warming the bike up, or even while it's running. Otherwise you'll overfill it because the oil will sump down into the engine from the oil bag and give a false reading. Also many have found that filling to high on the dip stick is too much, the bike will blow off the extra and settle with it toward the low end of the stick.

Great, thanks everybody. I'll go check out the knowledge vault.
