I had the mod done and took it to the track to be tested. the result about a 1-1.25 mph average improvement. this is of course with similiar track conditions, humidity and air temp. the box was done just like lee shierts did and the intake ports were done also. All in all it was definately worth it. However, when I go to higher altitudes (mountains) the bike stumbles when the throttle is opened up all the way and it even happens sometimes in the city. the bike is completly stock. I was thinking i need a p/c or yosh box. Any suggestions?
