I am fairly new to the motored biking. I have two Chinese engines. One 80cc and one 49cc. I

Both have black nasty oil dripping on the floor after I park them. It is coming from under the engine.Does anyone know If I can stop this or is it just Characteristic of these beasts?

Thanks for the help.

I forgot to mention that. I thought it was the exhaust as well. But it is actually running all over the back motor mounts of both engines. It is not a clean oil ( I use blue 2 cycle ) it is a wet Black gewy stuff.

It wasn't the exhaust pipe like I thought, and both engines seem to have it in the same place.

Is there some type of gasket in there?

Prolly not it - but I just spooked myself (not you guys spookytooth lol), I was doin' my usual "preflight" and I noticed the underside of MY motor was covered in "wet Black gewy stuff"

Yeah, well... as it turns out I was just a bit too enthusiastic last time I oiled my chain heh

I was getting that as well, was almost a tar that would run down the mag cover and was in the cooling fins. Snugged up the exhaust nuts and switched to Opti-2 and it went away.

It's funny to see people use 16:1 mix which is about 3x what's needed then wonder why their bike leaves a black trail of oil behind. :)

When my carb was running rich it would spit black crap out of the exhaust. And since my exhaust gasket leaked it would come out there too.
But after I fixed my carb and got it running right, the black greasy nastiness stopped.
