Surging FIXED !!!!

After reading this on the BMW Sport Touring website about surging I thought I would give it a try.

"Tomb9 utilizes a different procedure: "I've spent some time diagnosing my surging, and I have a slightly different take than the zero-zero adjustment. As mentioned in other posts, the surging is a result of the overly lean mixture on US bikes. The zero-zero procedure attempts to adjust the TPS to richen the mixture, but misses the point. The fuel injection uses the TPS to indicate throttle opening, so it can be adjusted to increase the amount of fuel without increasing the amount of air. The results are a richer mixture. The procedure is simple. Pull your left fairing cover. Get out your trusty DVM and attach the minus side to the battery negative terminal. Attach the plus side to a pin and stuff the pin into the end wire of the TPS connector (red/white). Turn on the ignition, but don't start the bike. The DVM will now read between .300 and .400 volts. The optimum setting is .395. Loosen the screws that hold the TPS in place, and rotate the TPS until you get 0.395 volts. Tighten the screws and crank on the throttle a few times. Reset the screws if required to get the correct voltage."


I took a reading of the TPS and it was set to .358, so I hooked up the Digital Volt Meter by shoving the positive lead into the red/white wire area and plug negative on a unpainted bolt, and set the TPS with the two screws to .395/.394.  


Took a test ride, and boom, surging all gone, nice to finally get that monkey off the back, as a summary, I replaced the spark plugs a while ago with Autolites, did not help, but not a bad replacement from Wally World anyway, TPS setting .395, FIXED !!!, I will monitor fuel consumption, as the throttle is now running a bit more rich, spark plug condition will be checked at next maintenance also to verify not running too hot.
