Kindly Note:

If you want your motor with this dio reed valve kit assembled more power and more fast, you need do something by yourself.                                                                                                                        these are good suggestions from our buyers. 

Firstly,change stock head to racing head; 

Secondly:port the other ports , like the transfer ports , and exhaust ports, and use a expansion chamber exhaust system ,                                                                                                                                  if you also jet the bigger carburetor such as a keinin 17 or 20 millimeter dirt bike carb,then the absolutely screem 

Thirdly:if you know how to port the piston and make it be window sleeve piston, it will absolutely make engine more power and fast.
