I bought a used '05 V-Strom 1000 in November with 4K miles on it. The chain appeared to be covered in dry lube and gunk, like the previous owner had maybe oiled it once or twice, then neglected it. I have oiled it a couple times with 80-90w gear oil like the manual specifies.

After installing a centerstand last week, I got to work cleaning and oiling the chain. But what I noticed is that when I give the rear wheel a good spin (think "Wheel of Fortune"), I only get about 1/2 or 3/4 spin before it stops. My old Honda Nighthawk 750 would spin about 2x, but it had a drum brake out back. It would seem like this extra drag is not helping my gas mileage (30-35mpg commuting in cold weather - with 3 minute warmups).

Here's the question -- is this normal? I'm thinking the rear pad may induce a slight drag on the brake rotor as the pad is always slightly touching it. Or, maybe the chain/O-rings are "dry" and need to be lubed some more to become flexible again. Or, maybe this is normal.

Any thoughts? Thanks!

Ride safe and God bless.

It's probably the difference between the disc brake and drum brake. The springs in a drum brake pull the shoes away from the drum when deactivated. If you took the bike out for a ride around the block and never touch the brake pedal, I'll bet the wheel spins better as the trip allows the tiny irregularities in the disc to push the pads away slightly.

After I get my new center stand put on (maybe tonight), I have a feeling my wheels will do the same thing and only spin 1/2 a rotation. Just seems like they will from how they feel when I roll the bike on the ground.

I can't remember what it was with my last bike, but I'm sure I could spin the rear at least one revolution.

I don't think there's any way to adjust the breaks for this. Is there? It drives me crazy to think there is that much drag by the brakes even if it's not a bid deal. :)

The pads on disc brakes back off from the disc due to the very slight warp (runout) of the disc itself....it is not perfectly flat. As you turn either tire you'll hear the pads rubbing the disc just slightly.

Next time you go for a ride, stop somewhere and touch the back disc....be careful of it being hot. If it is very hot (hot enough to burn you) and possibly looking a little bluish you either have a horribly warped disc or the pads are not sliding back a touch. The discs should be warm to the touch but not unbareably hot.
