Calling all rancher 420 pros

I’ve got a 09 rancher 420 with the ES that I’m having a few issues with. The bike is having a hard time shifting. Sometimes I can get it into first gear but the display shows 5th!! I can also get it into reverse sometimes but the display displays a blank line. In reverse the bike seems to be slipping. I can shift it Manually into other gears but often pops out when I get up to speed. I have already replaced the angle sensor already. Also does anyone know if you can adjust the clutch on the Honda 420 ES? I know where it is on the Manuel versions but can’t seem to find it on the ES. Any help would be greatly appreciated!
