Use of am extended intake on your stock motor, will not give you a high performance bike. I estimate a gain of between 1-2 hp if done correctly. but I was trying to warn you ,if done incorrectly you could actually lose performance, That may at first glance, not seem important, but in a passing situation on the highway your bike that before attained 85 mph, may now attain only 70 to 75 mph and be slower(require more time and distance) getting there , passing now becomes less routine and more dangerous .
