Piranha 140cc Pit Bike Engine

Great pit bike engine

Overall the engine is amazing definitely can tell the difference between the YX motors the only thing that I wish was better was the harness length it's super short and I don't have no spots for my CDI box also I wished it came with a upgraded CDI box one with the rev limiter

Appreciate the quick delivery time and everything included in box. Double box packing also made me feel good they cared since most delivery companies jut toss boxes around and can break stuff. Appreciate yall!

Ran perfect right out of the box and it completely transformed my crf50!
