I will open mine right away, I want that 10 to 20 HP, I bet fuel mileage will increase and it will decrease arm pump. I wish I would have thought of this sooner.
I have about a hundred decals and stickers on the shelf. Do stickers increase power ? I know that my green jersey is faster than my red jersey.
I know that fart cans make the ricers go fast, and cold air intakes do not just make noise and cause throttle icing in winter, they do add power, the advertisements show dyno results.
One of the true joys of owning an old school, old technology KX500 is blasting past a group of arrogant 450 owners, who think thier "new" four stroke technology is so superior. And then watch them, in their own disbelief try to make excuses why that antique 500 passed them.
