Do YOU or someone you know have a drill press and machinist vise to hold carb? If so then you break down you carb. Get a 14mm drill bit or what I like is a 14mm or 9/16 counter sunk bit. The counter sink bit has 5-7 cutting blades on it as oppose to the 2 that a drill bit has. You are going to drill out the venturi of your carb allowing for more and to be pulled into each intake charge. You can also buy a larger 3/4 counter sink bit to make a velocity type or cone entrance into the venturi and still retain your stock choke lever. I dont have a cable for my cam at my house but I will get a bike and do a build for you at my house. I have a cam so give me some time and I can set it up live on the web for ya`ll. If this is ok with the mods, admin. I just joined so let me get my feet wet first. Remove the silencer and run a straight pipe now. Cut the entrance and exit to chamber on exhaust and remove excess length from chamber then BUTT weld pipe to chamber. This alone is gonna wake the motor up. The drill carb venturi. Walla, you just increased a minimum of 5 mph (MINIMUM) on a stock Cag. Not bad for damn near free.
