mysterious grease grime

So I had posted up before about some mysterious grease/grime on the Lt side. down around where the mid fairing meets the belly pan. I had found the kickstand switch a little loose and super grimey so i tighten the bolts. but it looks like oil or something is coming from one of them. If I run the bike on a stand well above temp nothing is leaking. seems to only be there when I come back from a ride. any suggestions? and I am not 100% this is where it is coming from that area just seems to be wet. And no other area is.

It COULD be nothing more than residual grease on the kickstand pivot due to overexuberance on the part of the guy who greased it. Wipe off ALL the grease, oil or what ever around the kick stand pivot and see if that cures it. If not then pack toilet paper in the suspect area to find where it's coming from. Oil leaks are tough to trace and the TP is a great way to follow it back to the source. No shit. heh heh heh.

I got mine. Boy do I ever got mine.

Yeah I see that grease grimey stuff on my belly pan undersides as well. I dont know where it comes from but I wipe it off every time I clean my bike out.

And it is in all likelihood chain lube fling as cambuster pointed out. I used the Dupont teflon stuff but somehow that doesnt fling at all though...so I dont know what the grease actually is....

There is a cover seal in that immidate area that can leak as well. It's part of the gear box and covers the gear shift shaft and surrounding area. Check that once it's all been cleaned good first. May need to be retorqued of the gasket changed.

I believe I know where you are talking and that is what I first thought.

It is not chain lube this stuff on the side looks and feels just like oil. its not a ton but enough to make a mess.

I will try the TP stuff for sure that is a pretty good idea. I usually just let it go and by the time I clean the bike it is defanetley grime but I have been watching it right after riding and seems to be more oily then grime.

yesterday I got home seen it pulled the HOT ASS fairing off the side and seen one of the bolts on the kickstand switch a little wet and the kickstand when moved back n forth was really wet and greasy as well. I wiped the kick stand pivot and everytime I worked it back and forth more oil/grease was there. when the weather clears I will be looking more into it.

Not that it makes it any more acceptable but this is actually a pretty common little annoyance on the bike, although MV by nature will be sure to deny even knowing about it for sure if you ask.

You seem to have eliminated everything else, so my guess is oil seeping past the clutch push rod - the design where the sprocket cover mates against the motor makes it very difficult to maintain an oil-tight seal here and there isn't a gasket, just a bushing where the rod goes through.

Chain lube on a hot engine resembles motor oil. Even the best "non-fling - clean" chain lubes will pile up grease under the sprocket cover, which then melts and runs down. Not an MV specific item.

I used to be fast....now I just dream about it.
