This is what I have been telling everyone at predatorowners, the procoms for the fuji motors were junk, they tore the hell out of the one way bearings due to them not retarding the timing on starting. So why risk it on the KTM motors. If I were to do anything I would get the Vortex. It is more expensive but I think it would be safer. I had the Dyna FS on my fuji motors and liked it but I have not seen any for the KTM. Does Eichner run a Vortex on his 525outlaws?Has anyone tried the Procom CDI? If so how do you like it and would you recommend one.
