Starter Shaft seals leak !!
Posted January 23, 2004 - 10:00 PM
I have been riding my bike in the snow quite a bit and beleive that the warm engine has been drawing moisture past the seal or that the moisture is condensation from the engine being hot in cold climates. The same problem could occur when crossing deep water and the engine is hot, sucking water past the seal and into the engine contaminating the oil.
Looking at the oil passage / gearway it appears that heat and condensation could be trapped up at the starter where it enters the side case, as the oil travels upward on the gears and any heat or moisture may be trapped up there, and could theoretically drain back into the enginr oil after allowing the engine to cool.
Either way I am not to impressed to see moisture mixing with my engine oil.
Just thought I'd mention my findings so you could all keep en eye on your machines!
damn Yamaha and their aftertought for a starter

I guess to make a long story short is, don't worry about that little bit of moisture, it will "steam" out when the engine gets warm again, and make sure to be regular about the oil changes.

It's just disturbing.
Thought I would share my findings and make everyone aware!
If your engine is hot and you run it under cold water, there is a very likely possibility of water being sucked into the sump past the one wimpy o ring sealing the engine/starter.
You'd think they would have used a double lipped seal like a countershaft seal or something.

I was contemplating a purchase but have not seen one first hand or gotten to check the lever pressure.
Ever since I played with EVERTS WORKS CLUTCH at the bike show I want one.
I think his was soooooo light because the slave cylinder was massive - like 2" in diameter thus vastly reducing the pressure needed to apply it,- the haudrailic fluid has so much surface area to apply pressure to that the lever pull was incredibly light.
The brand new KTM 525 clutch I checked out had lever pressue about 5 times what everts was!
Actually Everts slave cylinder looked like something similar to what you'd find on a liter sport bike.
I don't use my clutch much locally but when I go riding in the mountains in B.C. its mostly all really knarly 1st gear, slipping the clutch, handlebar wide slimy root and log infested single track.
