Finally got my speedohealer today and I put it on followed all the directions. Went out and retested my spedometer and it was 100% on, like perfect. Before I put the healer on when I was doing 75 mph I was really doing 66 mph. I have now become so sad. I thought I was so cool driving around corners at high speed. Now it turns out to be not so high. Now when I do 95 mph on the bike I am really doing 95 and that was a whole different feeling than before. Honda should be ashamed making us think incorrectly about our speed and our mileage. When you put this truth machine on your bike it changes much about the qualitys of the bike. All in all I love it. Now I can make fun of those people who tell me how fast they made that turn, etc, etc.
