[QUOTE="Constant Mesh, post: 237992, member: 615"] Likely a vacuum problem. You don't need four check valves and four vacuum connections. It'll work fine with one vacuum connection, one check valve, and a vacuum tank. You have so many vacuum connections that you may have a slow vacuum leak somewhere. The internal volume of the servo is quite small so you really don't need a big vacuum source. The engine vacuum is strong whenever the throttle is closed. It gets weaker as the throttle is opened. The vacuum is strongest when the engine is turning higher rpm's and the throttle is closed momentarily. I installed an Audiovox on my FJR in early 2004 and it's still works fine. I have one check valve, one vacuum bottle, and a teed vacuum connection to TB2 and TB3. I use this teed connection to make the TB sync easier. It's much easier to remove a short piece of hose from the two interior TB vacuum ports than removing/installing those little rubber caps. [/QUOTE]
