your bikes not getting up to temp when your riding it around,

all oils come with a anti-foaming agent, majority of groms see short sprints from A to B - which really never allows the engine to get up to full operating temp, which never allows the oil to get to the correct viscosity and not allow the anti-foaming agents to correctly work.

here is my engine case, its far worst then your milky oil, i have foam coming out of the filler threads, yes all the way up to the threaded portion of the dipstick.

my commute to work is like 1/2 mile, i try to let my grom warm up 5+ mins before i ride it in the AM, the engine case is still cold when i get to work sometimes, partially due to 20-40degree weather in the AM.

If you have foam in a water cooled motor, you got other issues.

Had a huge problem with this as well.

Go on a long ride and get it as hot as possible. Then when you get home and park it, vent the dipstick for a bit.

I did this a couple times followed by an oil change. It seemed to all drip down into my oil which I then removed. Haven't had a problem since, although ambient temps have raised since spring is here.

FXCLM5 nailed it, the Exact same thing happened with me. I was ready to head back to the Honda stealership and have some words, but the grom forum came to the rescue with the right answer. My problem is that I've even got water dripping from the joint where the header pipe meets the exhaust can. never seen that before.

I got jizz in my grom too. I changed the oil and try to ride and warm it up more often. most of my trips are very short so its a bit tough to manage. I usually smoke a cigarette after i start the engine to give it some time to warm up. will do another oil change soon when time allows just to get that jizz out.

6000 miles, still having sludge. all stock. the neutral light goes wicked from the sludge. also, a lot of crankcase pressure. need a comp. test. i guess its the 5 or 10 percent ethanol that turns into water, through the injector, through the rings into the oil. the nasty hole at the beginning of the rear muffler 2013/2015 model. spits out all that unburned crap, making the rear brake disc dirty, superb rear brake performance.
