The stack I got from Horizon fits the carb on my 100 perfectly. I certainly hope I don't have a carb from a .50 on my 1.00, or I am missing out on some huge power!

Torque Wrench's intake stack is for a Saito 125 which happens to have a carb that is too large for the Saito intake stack which was originally made for the 50.
