hi new unit working grate..
hope you are all safe sound keep motor and jet drive in house just bought new motor ready to change over if needed thinking about putting a bigger head on ? nedd to get some picks done to show you all cheers again for all the help happy new year to every one.
There are two options for changing heads. One would be to find one from an EX17, that is a direct bolt on that will increase power with a simple jet change. The other option is to find a KX head, carburetor, airbox, and cam. Much more expensive and harder to find, but will give you a little more power than the EX17 head. Figure 1-2 mph increase with EX17 head, and 2-3 mph increase with KX. Good luck and Happy New Year!
