Performance kit for QMB139 Scooters & ATVs


This conversion kit is 100% complete and all you will need to convert a 50CC 4 stroke scooter or 50cc to a fast 72CC version. This is nearly a 45% increase in size! All necessary parts are included in this 17 piece kit! There is nothing else to buy and we will include a CD with complete instructions or you can download them here.



NOTE: If you have the QMB139-3(not very common) you will need to mill the case a little bigger for the cylinder to fit.

This kit works with all Tank, Roketa, Sunl, Lance & NST 50cc 4-Stroke Scooters that have the GY6/QMB style engines. 

They are AWESOME!!
