Cruise Control slow to respond

Post by wingingit2 » Thu Jul 13, 2017 10:58 am



'91 GL1500SE (California) with Champion Trike @ '92 engine.

The problem I am having is the cruise control when activated takes maybe 20 seconds to get enough vacuum to operate. I need to hold the throttle steady until it starts to work. If I don't hold the throttle steady the speed will drop to 30, 35 MPH and then start to rise back to set speed.
The cruise was not working until I replaced the actuator, before engine replacement. Now it seems to be doing the same thing as before. I have triple checked the vacuum lines, one-way valve and even tried different controllers, Cruise( under trunk) & valve ( left side). The speed sensor checks good.

I have been working on this for 2 days so any advice would be helpful.
Thanks in advance.

Yes, the actuator cable was the first thing I checked. If I put vacuum to the actuator it doesn't take much to raise the engine RPM's. It also holds vacuum.

I believe there is a vacuum canister on the 1500. have you checked it for holding a vacuum ?

Yes, the canister holds vacuum.

I think I found the problem. I just decided to replace more hoses even though they all looked good, and found the one going to the actuator valve internally collapsed, I could not blow thru it.
Unfortunately I can't test it because the fuel level was low and I think it sucked up some crud from the bottom of the tank. I have to pull the carbs and clean the jets. I'll report back next week when I have time to do the work.

Sounds like a quadruple check of the vac hoses was in order

Oops forgot to update. That was the problem. And the carb problem was a clogged vent hose for the California emissions. funny thing was it was the metal tube portion that was clogged, not the rubber hoses.
