Today i was riding for about 3 hours and when we were about to head back i was idling in neutral when outta the blue my quad reved and damn near reved out i killed it tried it again and it did it again so i popped it in gear and idled back home trying to keep my revs down. after washing my bike it seems to idle pretty decent a little higher than normal but not bad. what could cause that? a fault in my tors system?
