If you've gone to all the trouble to remove the transmission from your bike, you might as well check and replace as necessary the following items (it sure beats taking the transmission out again).

• Clutch shaft (input shaft) seal.
• Layshaft (output shaft) seal.
• On four speed transmissions, replace both cover gaskets if disturbed (MG# 12201100 and MG# 12201500).
• On five speed transmissions, replace the single cover gasket if disturbed (MG# 14201110).
• On five speed transmissions, replace the O-ring that seals the pre-selector shaft (MG# 90706140).
• On five speed transmissions, replace both O-rings beneath the clutch input hub (MG# 90706203 and MG# 90706235).
• Replace the O-ring for the outer body of the throw-out bearing assembly (MG# 90706170).
• Replace the pushrod seals. Moto International [now out of business] used to sell a clutch pushrod seal kit MG# 14085900. It's a handful of small O-rings (5 or 6) that go down the hole in the input/clutch shaft to keep oil from leaking out the front of the shaft and into the clutch (MG# 12085901).
• Replace all of the crush washers (for the fill, drain, level-fill, and the plug for the selector pawl). I prefer fiber washers for the drain and level plugs because they require less force to crush and prevent leaks (and thus less chance of stripping the delicate threads).
