On Monday I (local bike shop) put new tires. Yesterday I realized that the front tire is up (the bike is on centerstand falls/turns to the right?!? You can see it HERE.
Why? The installation went wrong?

I'm pretty sure it wasn't before like this because I keep my bike almost always on the centerstand.

Thanks for any help/suggestion/idea...

Are you saying that while on the centerstand, the rear tire now rests on the ground instead of the front? Is there a change to the way the rear of the bike is loaded? More stuff in the top case or saddlebag?

I can’t think of how a tire installation could go awry and change the weight bias to affect the way the bike sits on the centerstand.

No. The front tire is on the ground. That's ok.
Yesterday, when I sat on the bike to go home from work, on the parking lot, the front tire went up - as it supposed to (I'm heavy SOB :D), and then the tire/handlebar turned right. It's like right side of the handlebar/fork/tire/... is heavier?!?!?
 
I can't imagine the weight bias being anywhere near far enough back to get the front tire off the ground - as is, there's a pretty significant front bias and I have to put a LOT of weight on the back to lift the front while on the centerstand.

When pulling a bike back, the bars often like to go one way or the other, so I find that when putting it on the stand the bars typically end up turned.
 
Inspect the installer’s work on both front and rear wheels. Inspect the front axle to ensure the spacers were put back in the correct places on the axle. But if that were a problem, I’d expect front brake or rideability problems to be obvious. It could be just a case of the randomness of which direction the bars fall, and the heavier front tire may have altered that behavior.

I was sitting on the bike on the video to be able to make the front wheel up in the air.

Often, but not always. Sometimes they stay in the center. In my case, now, it always turn to the right, even if it's couple degrees on the left - you can see on the video.

I can check this only if I take the wheel off, right?

Front wheel is wobbly on slower speeds. The faster I ride the wobbliness is harder to feel But if I let go of the handlebar the shaking is very visible.
I felt it immediately after I left the shop but I thought it's new tire. And I was more "concerned" about "diving in" of the front wheel. :D

You want to say that this is ok?

By the way, totally the same behavior was on the parking lot and in my garage.
 
This is difficult for “us” to diagnose sitting in front of a computer. You can visually inspect the front axle and see if all the parts are in place. Also, with the front wheel lifted, try to wiggle it to see if it’s loose.

If this were mine, I would take the front wheel off and see if anything is wrong before riding any more, not because it flops over, but because you say the bike is unstable when riding. Verify that the axle spacers are in their correct place and that everything was properly torqued. If someone else installed this front wheel, you have reason to be suspicious about the installation (which is why I do my own work).

I have used a Shinko 705 front and mine handled just fine.

If you want, show us close up photos of both sides of the front axle.

is your garage floor perfectly level?

True, but from your experience you probably have an idea (and you told me) what eventually can be a cause, right ;)

Good one!

I'll probably do that. Thanks.

It was a bike shop. Although not Honda specific shop (I'm in kind of "war" with them, but as I can see now, I'm the one who's hurt in the "war").

You're right, I should've do it myself... :(

I'll try to take couple pics tomorrow...

Perfectly? I doubt it. But good enough. If nothing else, it's happening at the same spot I always park, so I can compare to how it was before.
And the same thing happened at the parking lot in front of my office.
 
My falls to the right with the front wheel off the ground while on centerstand, I think it's normal.


Just came back from the local Honda dealer. Wanted to see how much/fast the handlebar goes to the right. Sadly, not a single one 700X/750X has centerstand so I couldn't check. The service guy said the same thing that it is "common" that the handlebar falls to the right, for the same reason mentioned here, the rotor, break and the ABS component. But, when I showed to him the video (the same I posted here) he agreed that it's a bit "...to quick, a bit faster than it supposed to..." and he thinks that the "tensioner on the steering steam is never adjusted for 24K miles" (or something like that - probably I failed in the terminology, don't remember well :D) . And he mentioned, before I did, that the handlebar most likely is shaking.

Guess what am I doing on Saturday morning?
:D
 
The steering head bearings are most likely what he was referring to.

As with chains, a little on the loose side is better than a little on the tight side.
 
I would verify if they balanced the front tire. You should see some small weighted tape pieces glued to the rim if so.(maybe 1/2: wide and an 1-3 inches long) Considering you mention a wobble, I suspect they didn't and that is why the tire is falling off to the right.
 
In my experience, balancing motorcycle tires isn't done side to side. On a bike with a single front rotor, I'd expect the weights to be on the other side of the wheel (in this case the left side), but the amount of weight involved is small enough that I'd be awfully surprised at being able to tell as far as the bars flopping goes.
 
There's a LOT more weight on the right bar with your DCT model - fluid reservoir, brake lever, throttle.... I would be surprised if it didn't fall to the right.
