Following the advice from the experienced 800 owners, I installed the UMP air box system. I also put the stock exhaust back on my machine in the process. The Big Gun exhaust was too loud for my liking. I’m a previous MX guy and know that when doing intake and exhaust mods on bikes, you sometimes need to do something with adjusting fuel delivery. 1. Should I go back to an aftermarket exhaust using the UMP system, or will stock suffice? 2. Should I get a fuel programmer and adjust air/fuel settings using the UMP system? Thanks for any advice!
