I was reading in a v post and someone had mentioned about upgrading the cdi on the KFX 700, and made it sound like it was a pretty impressive upgrade. Has anybody upgraded the CDI and if yes what brand did you go with and what exactally did you gain? Also if you change the CDI box do you have to rejet or anything? Any info would be great. Thanks

 

Get a FST or Dyna CDI,you might have to jet up one size.

 

if all your looking for is the bottom end get the moose module and you wont be able to hold on to it !

 

I ran the Dyna...it helps, now I run the degree key...more work to put in but a lot cheaper. If you run a kill tether, make sure it is not a grounding style on the Dyna or you will fry it. I'm not 100% sure but I think Dyna makes the Moose...same unit.
