Need a guru on grizzly. Got a 07 grizzly 700 eps guy said it has a big bore kit and has slip on exhaust on it. Also has the power commander 5 on it and it runs like crap some times. Don’t know how too tell if it has the big bore kit on it or not but can I just unhook the power commander and go stock? Feels like it’s flooding it out. Don’t want too mess something up but think stock might be best don’t know how too check it all…
