I recently purchased the 2016 XMR 1000R and installed the yoshimura slip on exhaust. I know that can am says that a fuel controller is not necessary with this exhaust but I feel like one needs to be added. So I thought I would ask is there any way of being able to tell if it is needed? If so which fuel controller should I get? I was considering the EJK but don’t know which one the gen3 or gen3.5
