You might try Redline V-Twin transmission oil instead of motor oil in the tranny. I had a similar problem and that fixed it. Besides that, regardless of what the MOCO says, motor oil will never serve as well in the tranny as gear oil.

Good luck,

Might want to warn you about using Redline Shockproof Gear oil in the transmission, There are side affects from using it. Namely Not a loud clunk when going into gear, easier to find neutral, no loud gear noise when riding, If you can live with that , then go ahead, a lot of us have done the same thing.

 

Sounds like just one more case of the MOCO saving about two cents per bike on cheap parts and then spending huge amounts on warranty repairs or just refusing to fix it and causing poor customer relations and losing future sales. They never, ever learn.

Seems like I read somewhere that the clinical definition of an idiot is someone who makes the same mistake over and over and expects a different result every time - hmmmmm...

 

Make them fix it.

 

Try going to other dealers and find one that will just fix it and not give you lame BS excuses, then buy everything from him in the future.

Just a suggestion.

Good luck,

John

 

That's interesting because most dealers I talk to recommend it in the tranny.

 

Here is my experience:

I had shifter seal replaced at 16000 miles. About $380.00.

I switch my 02 RKC to synthetic in all three holes at 17000 miles and oil started seeping through the gaskets on the crankcase, but “not” the transmission or the replaced shifter seal.

At 25000 miles and a year later, the synthetic oil doesn’t appear to be seeping through my crankcase gaskets anymore.

I may be wrong, but I think CVOs have a different transmission.

My guess is your shifter seal is wearing and the slipperier snythetic oil found the leak faster than the old oil.

Beary

 

Did you overfill the transmission? The level is to be checked with the bike off the kickstand.

 

If it is not dripping I would not repair the seal just yet, but would keep an eye on it. IMO you should drain the Syn3 from the tranny and install a synthetic gear oil like Mobil 1, Royal Purple, Amsoil, or Redline. Use 85w140 or higher and the leak may disappear.

Dog155 made a good point. Check to make sure the leak isn't actually overflow from the breather tube. It is the curved rubber tube located slightly above and rearward of the area you are referring to. If the dealer overfilled the tranny it can barf, but this is unlikely since it holds 1 qt. and that's hard to screw up.
