This OULI gasket remedies common factory gasket malfunctions on Yamaha YZ250 two-stroke dirt bikes, covering heat aging fragility, housing warping, oil and fuel seepage as well as track sand ingress.

It forms a solid pressure-proof seal between the crankcase and magneto cover, locking away internal lubricants and fuel blend while excluding mud splashes, fine dust and humid air.

It shields stator coils and key engine internals from rust corrosion and abrasive damage, preserving snappy throttle feedback and steady ignition for motocross events and off-road practice sessions.

Precision manufactured to rigid OEM sizing standards, it supports fast swap during regular race servicing, cuts down repetitive part replacement expenses and prolongs the service lifespan of the 2-stroke racing engine assembly.
