If you have reverse: This engine comes with the short transmission shaft common on Yerf Dog and Crossfire 150s. If you have reverse you'll need to install the Reverse Output Shaft into the transmission. You could use the shaft from your original engine or buy a new one Reverse Shaft. We have detailed installation instructions for changing the shaft, you'll just need to follow the first 8 steps of the guide.

It's also a good idea to grab a couple exhaust gaskets for the install.

This engine will fit nearly every buggy and ATV that already has a GY6 engine installed. This will replace SUNL and ROKETA engines as well.

Engine is shipped DRY with no oil. Be sure to add 750ml of 10w40 to the crankcase and 120ml of 80w90 to the gearcase before starting.
