I found a vortex cdi for 225 dollars but it don't have the switch that goes on the handlebar. So I'm trying to decide what is the best bang for my buck between getting an exhaust or the vortex cdi for my 08 450. I race the local desert series here in utah and motocross as well so being able to change the maps a bit would be nice. Anyone using a vortex on this bike? Is it just a plug in and go type thing our is there any other rewiring that needs to be done and can it be run without the switch? Thanks in advance!
