ait valve hose attachment location

Post by goldwing94 » Sun Aug 11, 2019 6:37 pm



I have a 94 gl1500 that I am putting back together after sitting in parts for 2 years. I am having a problem finding where the vacume line for the intake air temp valve attaches to the engine. The line has a "t" on it. One line goes to the ait valve, the other line goes to the bottom of the breather to the bimetalic valve. The other end of the line goes where? One manual shows the attachment port on the front of the left carb. No luck. Another shows it on the 2nd cylinder intake on the left side of engine. Again, no luck.
Any help will be greatly appreciated!!!

My vacuum diagram shows #3 Pink tube going to the IAT thermal vacuum valve (bimetallic under the breather) #2 Pink tube going to the IAT vacuum actuator (top front of the breather) and #1 Pink tube going to the bottom front of left carb. The TEE is also a check valve.
In the bottom two views, it looks like the connection is hid behind the linkage.
