Yep, had issue where throttle would randomly cut out and would only work again after turning the ignition on and off 3 times. At first the husky tech and I thought it was the display after it had been changed for fogging, but it turned out to be the throttle grip, bearing in mind that it is ride by wire throttle on these, so the grip holds some electronics.
I assume you mean the cluster that holds the startbutton instead of the throttle tube/grip. The throttle tube/grip is just a bit of plastic and rubber. All the electronics is in the cluster on the handlebar.
