Cover Seal for the side of the crankcase for Rotax Max Evo Kart Engines. Made of a soft brass, this seal fits into the side of the crankcase to fill a hole in the case. This cover is also called a 'freeze plug' by some engine builders or tuners.
This hole is normally used for an external starter mechanism on some engine models, but not on the Rotax Max Evo line of kart engines.
Each cover is 20mm in diameter.
