I'm having trouble with my 1992 gsxr 1100 pouring oil out of the breather on top of the cam cover. I put a catch can on it and have to drain it after dragstrip pass. The motor dosen't smoke or burn oil. Can anybody HELP.

I don't know about your GSX-R, but some breather systems collect oil mist from the crankcase in a baffle in the airbox which should be routinely emptied. My CBR has a drain plug near the rear brake pedal. Maybe yours is full, or a breather hose is blocked or kinked. On the bad side, you could have excess blow-by past the rings that is pressurizing the crankcase.

I had a leak down test performed and everything checked out just fine. I was told that it might have too much oil pressure. Is this a logical explanition or are they blowing smoke up my ass.
Ummm...too much oil pressure doesn't make sense.

Is there any kind of strainer element under the cover? Usually the element catches the oil mist and lets it drain back down into the case.

Also, a leak-down test doesn't tell the whole picture...what was the percentage leak in each cylinder and did they do a compression test as well?

And as Jeeps mentioned...do you have the correct oil level?

If a bike doesn't have a centerstand or you don't use stands (who does when they check oil?) the oil level could be off by a quart or more.

Here's what the owner's manual states for my 1990 CBR1000: "1. Start the engine and let it idle for a few minutes. 2. Stop the engine and put the motorcycle on it's center stand on level ground. 3. After a few minutes, remove the oil cap/dipstick, wipe it clean, and reinsert the dipstick without screwing it in. The oil level should be between the upper and lower marks..."

Nobody is going to do all that, but I did when I first got the bike. Now I check it on the centerstand when it's cold and keep it at the upper level. If someone didn't read the owner's manual for my bike and screwed in the cap/dipstick before reading it, the oil level would be low. Anyway, his Gixxer has too much oil in it.

I was hopeing it was that simple.

Most of you sportbike have sight glasses and all you do is pull it level and off the sidestand to check the level...
The GSXR does have a site glass.

My Suzuki has a sight glass and a centerstand so it's easy to accurately check the oil. But if you tilt a level just a degree or two off level, the bubble rises to the other side. A rider concentrating on not tipping over the bike and reading the oil level can tilt the bike five or more degrees off level, but still think it's level. I mean, what are they using for level view? The seat? The handlebars? And the driveway or garage has to be level. The oil level will read high or low if the bike isn't absolutely level.

I actually use a free standing wheel chock now. Before, I use my Pit Bull stands. Before that, I would find a balance point and try to maintain it while checking the oil level. It is much easier to have somebody help with stabilizing the bike while the other checks the oil level.

Oil level or pressure level doesn't sound right either...you got too much air flow blowin the oil out...is your valve cover correct for that engine-maybe a missing baffle or checking blow-by you need to check each cyl. w/ the piston at different spots in the cyl.,one or all may be severly tapered or elliptical.
