I THINK HE USED A #78 MAIN JET ON THE "H" MOTOR

YOU MAY WANT TO GET SOME SMALLER MAINS IF ON AN AUTO CT70

it works fantastic! Here are some pictures of the installation if you want to share the info with other costumers. I used the 90 degree top adjustment tube from my old carb (shortened it a bit)and I made a small bracket for the petcock. I took out the rubber restrictor that resides in the stock air box snorkel tube and cut the tube in half to increase flow. The bike is a CT70K3 with a HK1 4 speed motor. It's geared up(14/35) and runs 50 mph with the new carb and intake.
