2005 WR450. 168 main, 48 pilot, JD red #5, WB E2 pipe, snorkle removed, Boysen Qucik Shot, fuel screw 1 1/2 turns. Alt 500 ft. The quickshot really helped with the initial surge when I hit the trottle. The problem I am having is there is a lag after the initial surge and when the power comes on. Is this a needle adjustment? I think it is wanting more gas but I am not sure. Any thoughts???
