Aftermarket CDI or EFI Mods for 2009 Mule?

[rjestes3]

There are several companies that advertise custom or programmable CDI and EFI modules for ATVs and UTVs. Does anyone have experience with these aftermarket modules in general, and more specifically in relation to the newer factory EFI engines?

I would like to have a little more speed from my 2009 Kawasaki Trans 4X4 Mule (KAF620R9F). It tops out at 24 MPH with a surge caused by its electronic governor.

My Dad always said that if aftermarket products really improved performance, the manufacturers would already be incorporating them....

Happy Trails!

Listen your machine was not made to go pass 24mil per hour,you add a cdi or powerbox ur reliablity will go down guarneteed BUT it may not harm it much, ur universal and stuf was not made for speed so keep in mind, dont overpower it or ul be in sh#t, I was looking into one befor i bought my teyrx, Up size tires will make a huge differance, id go with 2-3 sizes bigger, they have enoughlow end to do anything(i had 07 mule 3010), Ul prob get 15mph more, id adda KN filter as well then see what else it could improve on
