I have been discussing labyrinth seals with some Yamaha owners.
These are designed as a non-contact solution to sealing, used at crankshaft partitions of multi-cylinder two strokes.
Some say that they can wear and lose some abliltiy to seal.
Does anyone have experience or knowledge of this?
I'm interested to learn how this could come about.
I can only find that Yamaha used this type of seal in their motorbikes, like at the centre of the 100cc twin.
