SOURCE: stop oil leaking

It's either a defective gasket (wrong shape or inconsistent thickness at seal surface) or poor installation (installed with a wrinkle, overtightened, etc.). Clearly it's a problem and not by design. If you're going to design something to leak, it's easier to do without a gasket! :rolleyes: Tell the Scuderia boys to fix it right. Should be warranty work, I'd think.

SOURCE: oil leaking out of overflow

just check the crankcase filter to make sure it isn't stopped up if it is that will make the crankcase build up pressure and blow the oil out

Yes, the water seal is leaking. This is the indicator hole for the water and oil seal.

SOURCE: oil leaking from clutch push lever

Sounds like a worn seal. If you remove the cover and knock out the seal any atv dealer should be able to replace it.

Hi, this is whats known as. A slipping clutch, normaly the clutch slips when the fibre clutch plates become worn, remove the oil filler cap the ware would be evident if as you describe it has reached the stage of loss of drive by smell as the fibre plates have burned away, the main cause may be for a number of reasons, on cable opperated Clutches malladjustment no free play at the lever will cause the clutch to slip untill it becomes worn , hydrallic opperated systems rely on fluid in the system to opperate, if the fluid becomes warm the pressure increases putting pressure on the clutch, thus the clutch slip, my guess is the plates have become worn, remove r,hand engine cover to check, paul

Im not to familer with te zx12r, but if you are springing oil leaks it could be down to over pressure in the crankcase/engine. Check all your breather hoses are not obstructed or kinked (normally a large diameter rubber hose that goes from the engine to the airbox.
I am guessing you have already changed the cluch cover gasket? Im afraid they will need changing if you want an oil tight engine.

2003 yz 125 clutch

This sounds like dirt and grit in the oil is causing the clutch to grab. Change the gearbox oil. Ride the bike for a couple of hours using the clutch often. Now drain the oil again and put in fresh oil. This will flush out the dirt and grit. Use 10w40 motor oil. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell. Do not use synthetics or oils with "special" additives.

Other possible causes are > a need to adjust the clutch lever for 1/4" free play at end of the lever > warped clutch plates or friction plates > Clutch has been worked on and assembled wrong > low oil level in the gearbox > frozen clutch hub bearing > Incorrect clutch cable being used.

Please post a comment after the double oil change. The 2x oil change is a cheap way to eliminate a possible cause and hey, it isn't gonna hurt anything. If you still have the problem I can help with a clutch rebuild.
