i was out riding last night and i was going about 30mph and not real sure how i did it but i hit a good bump of snow in the road that i wasnt really expecting to be there and i assume my knee hit the shift lever knocking it into low while moving and boy did she grind. its seems fine shifting fine accelerating fine did i mess it up.also i was wondering arcticcat says dont exceed 5mph while the locker is engaged is that for safety reasons or because the locker cant handle it ? i would assume safety but im not sure i dont want to mess anything up. thanks for the help
