It was not at one time. It was over the course of the trip. I did install the larger push rod last week. I'll report once I get some miles on it.

Default m8 oil transfer

My 2017 M-8, along with my co-plaintiff, are in the shop for the last, best and final fix to fix all fixes. We pick them up tomorrow and drive 1000 miles and re-measure the fluids. If there is 5 0z's or more fluid transfer HD will buy back our HD M-8's. Court documents.
The HD shop put a vent in the primary very similar to the one in the transmission. Will let you know in 1000 miles.

Interesting, please update us. The vent is reported to work sometimes, not always.

Just to be clear here, this is not a class action suit? Did you and your co-plaintiff have to file suit in a local court. I hope you get the results you are looking for.
This reminds me when Harley crank shafts were having a lot of run out problems a few years back. Suddenly the MOCO changed the allowable specs from 4 thousandths to 12 thousands. Beware folks, this company has a long history of doing crap like this to avoid taking care of their design errors.

if you have any mountains near you, make sure you hit them within the 1000 mile window. My transfer was nearly double in the mountains, versus regular daily interstate commute. While I donít solid evidence as to why, my hunch is the crankcase pressure and ventilation changes are greater with the sudden deceleration and accelerating. My riding is more aggressive than just the normal steady cruise. Not sure if you have the same condition or any hilly areas to load the engine through a wider range, but just thought Iíd share my experience. 4-6 ounces in 200-400 miles in the mountains easily. Doubled with the deflector button installed.

Good advice. I had put on about 23,500 Km (of varying riding conditions) with absolutely no transfer issue at all. Then one weekend I had the occasion to ride through some mountains. One in particular had an extremely long and steep grade in warm conditions. The transmission oil was off the dipstick prior to my next service. We measured the oils to find that it had transferred 8 ounces within the last 4000 km.

Just got a 19 RGU. Other than checking the gear oil level regularly is there anything else or other symptoms I need to keep an eye and ear out for?
