New bike, only 6 miles on it. When I sat on it in the garage intending to push it back by foot power so I could turn it to gain more room at one side, I pushed back about 4 ft - no problem. When I pushed ahead, I could only move about 1 ft before it would becomeprogressivly harder to move, finally pushing itself back again like a wound up rubber band. Any ideas would be helpful. Also had to start it to move it ahead and although it feels like the bike has to overcome some initial retarding force, it moved forward about the 4 ft I needed. Can't figure this out.

Give it another 6 miles to sort itself out.

Is the bike in neutral or in gear when you're pushing it?

My 09 is extremely "Cranky" when being pushed. The clutch adjustment feels correct, but it doesn't want to muve even with the clutch lever pulled in. The front brake (anti-lock) seems to drag also....

The good news is at about 1000 miles it is getting easier and easier to move. The front brake drag has decreased and I can even move it when in gear although it's still better in neutral. Anyway, it's improving with miles.

Just a rough guess on this might be the rear belt alignment.

If the belt alignment is out, it would always run off to the same side of the pulleys.  When backing up the bike by foot, the belt will be running to the opposite side.

Sometimes at very slow speeds, while pushing by foot, the resistance is such that it will resist the foot power.  Under power of the motor, it will probably just start wearing the side of the belt against the rear pulley.  I've only seen one drive pulley and it was way wider than the belt so I'm guessing any guiding the belt might need is done by the driven rear pulley.

I know that on timing belts at work, sometimes if out of alignment, they will rotate by hand one direction but lock up in the other.  When powered up they just run and wear the belt.

I'd look at the belt for excessive wear or black powder on the rear pulley or the area exiting the front trans drive pulley area.  You may also see a VERY shinny side of the rear pulley compared to the opposite side of the pulley guides.

Good luck, but get this looked at quickly.

At 6 miles?

Hey Louis, just speculating on some odd ball thoughts.

But if the rear wheel was out of wack from the get go, that could explain it.  And yes, wack is a technical term we use at work quite a bit. 

I'm not going to go out on a limb and say it has to be a belt alignment problem, but I've seen this same symptom in other timing belt situations similar to this.

I hope it IS clutch drag and that it will go away as more miles get put on the bike, but I've never seen a clutch drag situation that gets increasingly harder as you move it backwards further.

So I think we'll all be interested to find out the root cause of this strange symptom.

Cany chance it could be a tire pressure issue?

And now from the cheap seats....

Does your garage floor slope?  Most do.
Drive into your garage and do a U turn. 
Now I'll bet it is easier to push forward and harder to roll backward.

As Homer would say DOOOHHHH!
