does anyone know the cheap way of upgrading the air intake on the joyner 650 spider without buy the expensive performance packages that company's like team joyner/thunder sell. it cant be that hard but i just want to know what others are using.

 

Check out buggynews.com, there are several members with the joyner 650 that have done upgrades. They will be happy to help you out. I have the 800cc Motous buggy myself...
