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, and the EHS Racing air box mod, etc.
I lost a lot of my articles during migration to this new web site, but will be reuploading photos/videos, and editing & updating these articles actively throughout Fall 2024...
