I tripped over this purely by accident. The lead in was-clear plastic oil sump and valve cover. I think he is Russian-not many language "skills" on my end-and watched them try a couple different plastics then mount the new plastic parts oil up the engine and run the engine. Interesting to say the least. And found out the WHY of keeping oil level in parameters on an OHC engine. Also saw on another vid where the attempted and succeeded to water hydro lock a running engine. And the aftermath of the hydro lock. There IS a long list of things he has done!

Figured some of the other gear heads here along with non gear heads might git a chuckle or three!

RIDE SAFE.
