I installed a Sparks full system on my son's 06. It has a HRC kit and HRC jetting, it ran perfect with the stock silencer but now there is a terrible bog when you hit the throttle from idle. This carb. is totally different from my 05 and I did't have this problem when I installed a full system on my HRC 05. Help please!

put a 55 leak jet in it and that bog will go away...
