2012+ Stumble

[Cruiseman]

How many of you with a 2012-2014 are experiencing the cold engine stumble where your bikes briefly loses power between 2100 and 2800 RPM?

[Rick S]

Mine does

[PGLong]

Mine also, 2013, but it lasts only 2 minutes or so and then never happens again..

My 13 has not stumbled yet...I hope I didn't just jinx it!

My 13 has not stumbled yet...I hope I didn't just jinx it!

If memory serves me correctly, mine did not show up until I had about 8,000 miles on my 2012.

My 2012 just hit 10K and no stumble here.

[MondayBlues]

I have about 17k on my 2012 and so far no stumble. Knock on wood...

So far no stumble. Only got close to 6000 miles on the bike.

A lot of owners report no stumble. We are not sure if this is because some Goldwings never develop the anomoly, or, if they all do it, but due to individual riding styles, it is not always noticeable. I notice mine because I follow the same routine every morning. I start the bike, back out of my garage and head out of my neighborhood for coffee. By the time I get to the second left 90-degree turn, the temp gauge is at about 1/4. I accelerate to 30 mph in second gear and within 1/2 a blog there is a noticeable drop of about 200 rpm and temporary loss of power. It happens in almost the exact same location every morning.

I have a 2012 and ride all year if possible, when it is cold out I have to let it warm up for 3 to 5 minutes before it accelerates correctly.

No stumble here.

[BobMak]

2012 with less than 1000 miles and dont remember anything like being described.

[Redwing2012]

Mine 2012 started within the first 1000miles.i have leaned how to deal with it.I,m still waiting for the Class Action Lawsuit to Honda. 😠😠😠😠😠😠

[LoneriderSr]

2014 600 miles no stumble yet, no wobble yet....

[Recore]

I have a 2013 with 18000 miles stumble started at about 15000 after it warms up no problem

[vmaxed]

So far no stumble on my 2014

I've got a little over 27,000 on my 2012 and have only seen the stumble happen a couple of times. Usual routine is about a 1/4 mile ride down my dirt road to the pavement and then accelerate briskly up to 45 mph. From there, I'm on the highway, so my bike doesn't stay at low RPM's for long. I shift somewhere north of 3K RPM's. This seems to work for me, but I am still considering an ECM reflash.

Mine does also, so I just make it a habit to keep the revs up until the engine warms. Thankfully I only notice it for a couple minutes after I start the engine. I know some guys report it happening after starting when the engine is already warm, but I haven't gotten that yet.

Only have 4000 k's on our 2013 airbag model no issue with engine stumble yet and hope it wont appear in the future

As you probably remember, I was pretty vocal, when you originally started mentioning this, that mine didn't stumble. As time went on, I learned it really was riding style. Here's the history I have with it:

I bought my 2012 new in September of 2012. Cooler weather had already started, so I was wearing my Colorado Chaps and Tourmaster Flex jacket. For convenience, I'd start the bike, back it out of the garage, then gear up. My belief is that this routine allowed the 2100 rpm stumble (that's where it hits on mine) to occur while I was riding straight, and probably as I was going through the gears, so I never noticed it.

Sometime around March or so, I quit wearing the chaps, and noticed the stumble for the first time. I wasn't turning on anything, just riding straight (and not changing gears) and I noticed a definite drop off for a split second, until I gave it a little more throttle. Because I had read about it, I realized what it (probably) was, and looked for it to happen again. It did, at almost the same spot each morning.

Then, the weather turned warm enough that I left the jacket at home. This meant that I didn't get off the bike at all, just started it up and took off. The first morning I did that, the bike stumbled as I pulled away from a stop sign, and I thought I was going to drop it. I emphasize that, because I've read several times from other riders that they "almost" dropped it. I'm not going to dispute their word on it (won't make that mistake again on the topic), but for me, it's more of a sensation that I might drop it, than it is a true "almost" drop it.

I eventually got used to the stumble, and was basically prepared for it, so I've gotten where I don't give it much thought; but it's most definitely there. I've since change work locations (same job, we just opened the permanent facility), and I don't have a real problem on the way to work (I'm usually shifting gears when it happens); but I feel it almost every time I take the protected U-Turn onto HWY 75 on the way home from work. I'm prepared for it, and I think even if I weren't, I'd be able to handle it, but it's there, and it is a bit worrisome.

I've been tempted to go with the modified computer to fix it, but really wish Honda would come up with an official fix.
