Well, I posted this issue back in Dec, and it still persists. My bike is an 03 DL1000 with 34k miles. it ran great back in NM, but since it arrived here in Dec, it has been running rough. The only prep i did to the bike to get it here was remove most of the gas (i could still hear a little swishing around) and disconnect the battery. I had the dealer do a 30k service before departing, which included valve adjustment and throttle valve synch.
The bike is equipped with a set of Staintunes (no baffles) and a PCIII. OEM air filter.
The bike had no know major mechanical issues before bringing it here and in the three years I've owned it.
Since receiving the bike I have done the following:
I replaced the battery.
I've added a fuel treatment to a fresh tank of gas...still runs rough. I continue to add a stabilizer to each tank. Min octane here is 92.
I've disconnected the PC III...still rough...reinstalled the PCIII.
I checked plugs (no issue), air filter (clean), and did a thorough inspection under the tank area...clean and nothing out of sorts.
By rough running, here is what i mean. At idle, it sounds "off," both cold and warm. It is almost a cyclical fall off of RPMs. I can watch the tach move from about 1100 to 1400 RPMs. Overall, i classify the idle as rough, and I've even had it cough and stall at stop lights. It starts back up with no issue, but this is not good in Korean traffic. At speed, between 2500 and 3500 rpms, it runs very rough. it will lurch about and the engine does not run smooth. Painful to cruise at low speeds in first and second gear. Today, at higher speeds, the engine feedback just felt rough, like a motor struggling to make RPMs. It got me home, but I was worried enough to cut the trip short.
Anyway, I'm hoping for some more troubleshooting advice.
I suspect an issue with the fuel injection system. I worry that the little fuel that was left in the bike, gummed something up. If it were a carb'd bike, I'd pull the carbs and give them a good cleaning, because this is what it feels like it needs (but it is not a carb'd bike). Any advice on cleaning the FI system...I'm all ears.
Wx is getting nice here, and there are too many good roads to waste time wrenching on this bike.
Thanks in advance.
