I heard the fix is to replace the dip stick with a candle wick, then it will pull the fluid up and always show full.

I guess I better start posting like so I can get up to 25 posts! I'm in the adjust levels and ride 1000 mile stall phase of this process.

Tech Services Open Ref #...
Transmission was low at 24 oz
Primary was high at 40 oz
Adjusted to 30 oz in both the tranny and the primary. Come back in 1,000 miles and check levels again.

Also replaced the Switch Pack, hand control - bike would not start in gear.

Talked to my sales guy yesterday - he had never ever heard of such a thing as an oil transfer problem. LOL.

I run Royal Purple gear lube in the tranny. Amsoil primary oil and 20w50 in the crankcase.

THIS^^^^

My "IDIOT" service writer told me that it's "physically impossible to transfer oil from the trans to the primary".
I asked him; "then where is it going?"

Gave me the 'ol deer in the headlights look........................

"My "IDIOT" service writer told me that it's "physically impossible to transfer oil from the trans to the primary".
I asked him; "then where is it going?" Gave me the 'ol deer in the headlights look "

My Service Mgr told me to do the transmission oil level checks when the oil was hot, like when returning from a ride. I looked at him like a deer caught in the headlights but did not say anything. I went home and read both my 2017 owners manual and my 2015 service manual for transmission oil level checks. One said check at "room temperature" and the other said "ambient temperature". This was the first time I actually caught him in a lie and I am disappointed. I thought he was a straight shooter based on previous discussions I've had with him over the years.
regards,

Default Current plan.

My current plan is to have them monitor it and get the oil deflector installed. Then install $toneColds kit and pretend the deflector works. If they come up with a different solution or I need Warranty work done can put it back except for the drilled hole in the actuator. Doable?

Why was he lying?? Maybe he wanted them checked hot?

I’m getting ready to test a small hole drilled in the metal part of the seal for venting. If it works that will be how we vent going forward. That way should the seal be compromised there won’t be any leakage.

That would be great!! I hope it works. Then we could de-mod the bike if needed (like for a new transmission!)

I'm curious if there is more information on why this is happening. I've read the speculation that maybe the primary is drawing a vacuum and sucking the transmission lubricant in. Or maybe there is a pumping action that is pulling it in? Venturi effect? I sort of doubt it's a gravity drain - but liquids do seek the lowest spot they can get to so it's possible.

I agree with the comments that this is not normal. Not sure what moco is thinking saying that - although it sounds like different people are saying different things and some may be going off script.
