This one I can comment on from experience. I work with two guys that have the same machines. Honda 300 4x4 and a big bear 350 4x4. The results are in - honda low end, mid range, and top end as well. Both are stock. Rejet your carb or put your airbox lid on. You are more than likely making a little more intake noise (seeming much faster than stock) and are not realizing any HP gains. Also, Your racing plug is probably hotter than stock and your engine is running hotter than normal. Result - loss of horsepower. Get your machine in order or you could risk getting smoked!
