So I’m new to grizzlys and to this site but I have some questions I traded my machine for a 2012 Grizzly 700 EFI I want to build a new mud machine. I get the thing home right after trading it now has a check engine light and is showing code 42 I down loaded a manual and it seems cryptic to figure out how to erase the code. I tried to ride it at 20+ mph and that didn’t help. Machine runs good just no speedo.any help would be great
