I have a 2011 grizzly with a EPI clutch kit an HMF swamp series pipe with HMF optimizer 27"zillas and a K&N air filter. The problem i am having is the 1/4 throttle to 3/4 throttle setting is not working, i can set it at idle (push menu once green light, push menu twice yellow light push menu three times red light) but when i am riding it goes from green straight to red i've go no yellow whitch is the mid range fuel delivery so it sputters and farts if im in the middle throttle position, i either have to be putting around or wide open for it to run good does any one have any suggestions on what might cause this... This has been happining since day one and i just now figured out how it worked..
