I finally got around to doing my winter maintenance. Valve clearance check and camshaft timing, seeing as I have the tools. I have a 2018 R1200GSA that has been throwing a random Left Throttle body correlation codes. Kinda a real pain in the butt as it goes into limp mode and I have to roll to a stop, shut the engine off and restart. Several trip to my Dealer back when the bike was under warranty resulted in a new left throttle body which coincidently didn't fix the issue. For several other reasons I didn't pursue trying to get this fixed at the dealer as I can probably fix it my self. A heathy dose of Stabilant 22 and a full Idle reset seamed to help as I didn't have any issues last summer, maybe once. Still when I graph the signal out of the Throttle grip with the GS 911 I get some wonky signals at idle. It is just a calculated value so do I believe it? I tried to get the pin out chart from BMW for my particular bike but that proved to be mildly frustrating so I have left actually putting the lab scope on both throttle bodies to do a comparison as to what actually going on for now. If it gets worse I guess that is where I am going and I will trace the wiring myself.
Anyways back to the maintenance. On checking the Cam timing I found that the left side was significantly out, multiple mm. Checking the right side it was spot on.. So my curiosity has me ask. Would the Cam timing, All the sensors are on the left side, mess with the intake/exhaust pulses enough to throw off the Throttle body adjustment adaption?? To the point it get screwed enough to throw a code??
Have I answered my own questions? I guess I'll find out once the snow has melted and I start riding again.
