[QUOTE="HAPPY JACK, post: 1443340, member: 29516"] Had a used 09 with trooper mod Resulted in idle searching poor throttle response and inability to achieve throttle body balance. Tapped the holes drilled in the rear of the mufflers with black oxide cap screws and never looked back. All the problems with the response were corrected and the bike ran great! Drilling airboxs and cans are things of the past and cause nothing but problems on modern motorcycles. If Yamaha could get more ponies by drilling hole don’t you think they would have already done it? [/QUOTE]
