2006 TRX 450 air box mods vs jetting

3028 Views 3 Replies 3 Participants Last post by  BIGBEE
Recently opened up the stock air box and developed a serious hesitation. Cover up the extra holes and the hesitation goes away. Problem must be in the jetting??????? Any ideas as to how much larger the jets must go? Any other solutions?

The 450 is stock for now. Just seems as if the air box restricks the air flow that much, alot of power can be gained with jetting. Would hate to keep the stock lid on it. All riding is done on the west coast at sea level.
