    Anyone know what this is??

    Black substance. I took the cylinder off my ski and noticed a ton of this stuff built up. I use castor 927 oil if that matters. Thoughts? Thanks!

    That's sludgy gummy build up from the bean oil......it's a great racing oil that REQUIRES frequent engine teardowns. DO NOT use bean oil in a rec 2 stroke of any kind, good way to ruin an engine.

    Thanks! Geez I thought I was buying the “good stuff”. Had no idea it would cause build up like this.

    .............which is synthetic, NOT bean oil. Klotz DOES still have "benol" which in fact IS still castor bean oil.
