It all depends on your ridding. Race, trail, desert, ect

a mix of trail, dune, overall go fast riding.

Better spark is always a plus!
The CDI box will change your timing curve alittle. It will also give you higher govenor. SOmewhere around 1000more RPM.

thats what im thinking. after doing some research, I dont think the msd enhancer kit is going to be beneficial to me quite yet. however, does anyone have a suggestion on a different ignition box??

I don't use one. I am unsure of a good product. I know of big gun. I have seen it in motosport.
