Okay, calling all Camhead owners to chime in. Here is my problem- We just took delivery of a new to us 2011 R1200R Classic with 74K miles. The bike was awesome the day we received it (Friday). The next day (Saturday) we took a 200 mile drive and about 90 miles in, coming to a stop, the bike died. Started back up and ran fine for the next 10 minutes, then stalled again. We stopped for lunch, about an hour, come out and it started fine. We rode 100 miles back home and when we pulled up in the driveway, it died again. I hooked it to GS-911 with no fault codes. I re-calibrated the idle actuators and started checking things. Waited about 30 minutes and the bike started and ran fine. I took it out all night for about another 100 miles of stop and go, and dinner, and gas. It started fine and ran great all night. Didn't ride on Sunday and Monday was raining. Tuesday, we went for a short ride, it started fine and about 30 mins into the ride started bucking like a bronco and sounding really bad, and of course it stalled out. This time upon restart, it idled very erratically and up and down and then after about 7 seconds, stalled. Finally it started and limped home, bucking and bogging down. Upon return home, it would not start, ....let me add, it would start if you held the throttle open, but as soon as you let go, it would die. And while you held the throttle on, it sounded horrible. I started taking the bike apart, I did find the tank vent clogged with rust, I cleared the line. I have talked with several people over the last few days, (thank you Don Eilenberger and Jim von Baden), and I came to the conclusion to order some coils. I received them yesterday, but I guess I was to hasty and actually got the ones for a Hexhead. I was going to pull the spark plugs and check those, but I have now realized I don't have a 14mm deep socket, so I will get one today. I have checked the fuel pump with the GS-911 as well as the Fuel Injectors and Idle Actuators. I am looking for some more input or maybe someone who has experience with this problem, or knows someone who has.
