Ok here is my question.  When my bike is cold from being outside and I roll my bike onto the road (it is under my porch in the back yard) there is a kind of rubbing sound.  The bike is in neutral and everything.

I am thinking it is just the medal expanding due to the cold but not to sure.  Any one else have this issue???

Also it is hard to put it on the center stand when it is like this.

Thanks for the help

Well, metal will expand with heat and contract with cold so it's not likely to be that. I get a slight "rubbing" sound from my front wheel but it has never been a problem. If you have a problem like this it is most likely to be some inpairment that may be visible, get on your hands and knees and have a good lock, pay particular attention to the inside of the front mudguard, I had a big lump of tar there once, the chain guard etc if that's not it then its possibly brakes but don't go adjusting brakes unless you are sure.

Centre stand could well be a matter of tecnique, there are 1001 threads about it that you could "search" out.

Thanks Cal,

I'll do that when I get home tonight if it is not raining.

BTW totally off topic but I am trying to get to England next year or so.  How far away is Lakenheath (the air force base) from Kent?

Rubbing sounds when cold are probably the brake pads on the front or rear disk.  The brake calipers on the GS are similar to those in a car.  They don't have very strong "return clips"  that push the pads back into the hydraulic cylinders when the pressure is relieved.  In other words, you're always getting a bit of "brake drag."  When it's cold, it gets worse.  the cast calipers get alittle smaller in the cold and your bike isn't running so that's why you probably hear it.  

but I'd follow the aformentioned advice anyway.  Check out your bike to make sure nothing is obviously awry.

I agree with Octous but you might also have some bad dust seals which is preventing the pistons from getting back to the start position.

Replacing pistons, pads and fluids is a piece of cake - very easy to do.

With the bike on the centre stand try to rotate each wheel to test if the brakes are dragging. There may be some drag but they should still be easy to turn. If the wheels are very stiff the brakes need work.
