[QUOTE="Constant Mesh, post: 307597, member: 615"] Inadequate vacuum is the most likely culprit. Borrow a MityVac which has a vacuum gauge and tee it into your system on the servo side of your check valve. Periodically monitor the gauge reading when the servo is working OK and then when it starts sputtering and stops working. The gauge should read approximately 10 inches vacuum when the engine is idling with the throttle closed. It should read less than 10 for all other running conditions except possibly when the bike is at speed and the throttle is abruptly closed with the engine at a speed considerably above idle. The vacuum source must maintain a minimum 6 inches vacuum for the Audiovox to work properly. A vacuum canister is necessary if the vacuum drops below 6 inches when the throttle is opened. Please provide a listing of your electrical connections. Where is the Audiovox wiring connected to your FJR's wiring harness? [/QUOTE]
