Has anyone used a A1 Vented Dip Stick and if so how do you like it?

I have a 2017 M8 and wonder if it is the right way to go for a sumping issue.

Thanks for your time.

Have you had the vent installed on the primary...?....

Bob, that will not help the engine oil sumping problem

The 17 model year engines had the first generation oil pump ( new and improved designs had a lip seal) and improved oil pump to help the problem

Not all engines showed this problem, same goes for the tranny fluid transfer issue, some did , many did not

[mighty mike]

To Bob no the primary is not vented. Bought bike new. All stock.

Mike, if your 17 is sumping have you tried running your engine oil only 1/2 up the stick?

Also let the engine idle for at least a minute before shutting down

While there are many good reviews on the vented dip stick IMO it is only a band aid

The real deal would be the updated oil pump with the seal IMO

If I’m not mistaken there was a service bulletin on the vent and your Dealer will put it on..

Mike, here is a link to the kit instructions in case the dealer will not warranty the job

Thanks to everybody who replied. I was concerned about the oil from the crank case of the engine getting

into the throttle body, not transmission fluid into the primary case. Does a vented oil dip stick relieve the

built up pressure from the crank case and if so does that help eliminate oil getting into the throttle body

from the breather bolts on the cylinder heads? If anyone has tried the vented dip stick how is it working

for you.

Have a Merry Christmas everybody.

Too much oil in the crankcase usually is the problem ...The oil level on the dipstick should be 3/4 of the way....Not right on the full line....Oil will seek its own level, Especially at high RPM's...

[mighty mike]

Thanks for the info, I will lower the oil level in the crank case. I checked and it was above the full

mark. Had the oil changed in all 3 holes late this fall just before putting it into winter storage at the

local Harley dealer where I bought it. It's hard to get good help these days. Maybe I'll start doing

my own oil changed again like when I had the 2 wheeler. Hey I am not lazy but being 73 I just don't

care about laying on the garage floor any more.

Stay safe everybody.

If you are sumping you can pull the crank sensor out and measure the oil that comes out

Any more than 6oz of oil the MoCo says is a sumping engine and needs attention.

I dunno for sure if the vented stick works on all cases that sump, it is hit and miss and kinda spendy IMO

Keeping your oil level down to the 1/ mark will help, as well as letting the engine idle down for 1-2 minutes after a ride helps some

The real cure is the updated oil pump with seal
