Description:

Ominous Motorsports is proud to offer our Yamaha PW50 and PW80 Oil Injection Block Off Plugs, the perfect solution for those seeking reliability in their two-stroke Yamaha motorcycles. These block off plates ensure a secure and leak-free seal for PW riders after eliminating the factory oil injection system.

The original oiling system in the PW50 and PW80’s were known to leak and fail, and at best deliver inconsistent oiling. Many people would compensate for this by adjusting the pump to add more oil than needed for engine safety, resulting in more smoke, fouled plugs, and less power. By removing this system and switching to pre-mix your bike will be more reliable, run better, shed unnecessary weight, and add peace of mind.

Our block off plates are precision-machined from 6061 billet aluminum and include a vacuum plug for the carburetor and all needed mounting hardware. Remember to immediately switch to pre-mixed gas after removing the oil injection system.

All Ominous Motorsports product are proudly manufactured in the United States of America.
