EHS Racing EFI Programmer & Barker's Exhaust!
So the HMF programmer that came on the bike had to go. It was running too lean and not set-up properly. I wasn't willing to risk damage to such a fine motor and lose value in it. I'd prefer to have the motor run better than stock and perhaps preserve its durability and longevity as a properly running engine.
Eric @ EHS Racing has been nothing but excellent during this seemingly never-ending project, and I believe we finally have a properly running 2019 Yamaha Grizzly 700 Special Edition. I moved to the EHS Racing EFI Programmer, Barker's Performance slip-on exhaust w/ Quietcore installed, and these upgrades along with the already-completed EHS Racing air intake modification, my bike is simply SUPERIOR to what it was before! THANK YOU EHS RACING!!!
Everything about my bike is improved...from idling to throttle feel & response, no "mushy" start to the thumb throttle, just a nice linear consistent feeling "all-the-way-thru", more power, more "GRRRRR", more everything. Did I mention no more backfiring / popping on deceleration? Wow, just drastically cut down on the pop, and now it only happens very rarely. I also did the AIS-block.
