Changed over to Mobil 75W90 Gear Oil at 3000 miles. Changed the gear oil again at 5000. When I popped the access cover to fill the case, there was a heavy white goo with the consistency of mayo stuck to the inside of the cover. The fluid that drained from the trans case was clear as should be. Is this the remnants of the Synth mixing with the stock fluid and sticking to the sidewalls? Only reason I'm asking is because my experience with a milky substance in any oil or trans system means water. Any help is appreciated. Blackhat | ||

I get the same goo. I was told it is condesation/moisture because I store my bike outside. Doesn't look right though does it? | ||

I had the same stuff on the oil cap of my 1980 Bonneville. I assumed it was "cooked" oil as the Pontiac was burning it bad. | ||

It most likely IS water. I had that problem when I was using other types of oil, but since I switched back to sportrans, I haven't. Take it for what it's worth. | ||

Want to clear out whatever you've eaten for several days? Get that tranny nice and hot, pop it open and take a good whiff. That Mobil 1 75W90 makes me want to retch every time I change it. Foul smelling shit. Only had that problem once, when I changed my oil after the NE tour. The bike was stored outside for 10 days and we rode in heavy rain a couple times. | ||

That'll do it. Also, while washing your bike it's a good idea to rubber band a sandwich bag over the tranny vent tube under the seat. A good blast with a hose at the edge of the seat sends water right down the vent. Not good. | ||

The white mung is caused by water vapor which doesn't get burned off if you take a lot of short trips (under 15-20 miles). It's a terrible thing but you simply must spend more time riding. | ||

What oil are you using? I changed to Motul from the HD stuff, goo be gone, it is all gone now. | ||

Fst Tyms, I'm running Amsoil 20W50 Race oil, and Mobil 75W90 gear oil. All Synth. Looking at the posts, it probably is a condensation thing. My bike is parked outside under overhead cover, but not a garage. I go on a lot of long rides (Georgia to Florida and back) but from home to work is less than a mile during the work week. This was also the gear oil that was drained after the past winter in which the bike sat a lot more than than the spring or summer months. Blackhat | ||

I park outside too. In a carport. But I agree it could be condensation. I was using the synthetic screaming eagle stuff. Now that I am using the motul, no more goo. THough it could be from a weather change.  | ||

I use the mobil1 stuff also. Bike is parked outside, under a cover. I notice the goo if I change the fluid with out riding the bike for 10 minutes like it says in the manual. I always figured it was from a component of the lubricant not heating up enough. When I ride the bike and then change the fluid out I dont notice it as much. Havent had any problems either with the tranny, can this condensation cause problems? | ||

I rode the crap out of my bike wed night came home let it cool a little and did a full service } it before i do it but this time I had the fan on riding and it was only about 60 degrees (favorite back road/no traffic)}} |
