vacuum line question

Post by pcua28 » Fri Jan 23, 2015 10:31 pm



Could anyone tell me where this vacuum line connects to? Behind cruise actator there are 3 metal lines, the closest one to you sticking straight up which is middle metal line, what hooks to it. Trying to attach imagine. Any help really appreciated. One more question will this missing cause poor gas mileage and low rpm studder? It is a GL1500.

If this is an 89 you have I am fairly certain it should not have the 3 metal vacuum tubes they started that in 90. The bulk of the vacuum lines on the 89 should run off the right side no. 3 intake with a plastic multi connector just above mounted to the frame. Something don't sound right.

The motor is a 1994. Sorry it slipped my mind. Bike is a 89. So any idea on 94.

U got a whole bunch of studying up on the vacuum line diagrams to figure out what is connected where now and what might be missing.

Everything is 1994 as far as engine. I just need to know where that vacuum line connects to at the other end. It is the first metal line from the left with the red line going through it, first turned up pipe.
