I recently had some work done on my bike. Since getting it back from the
shop it feels like it pulls to the right.

Were there any Bush posters in evidence at the shop?

The work I had done was related to
the drive on the right side of the bike and new parts were installed. Is
it
possible that this has thrown off the bike's balance? Has anyone ever
experienced this? Is there anyway to check a bike's balance and then
correct
it if it is off?

Make sure the frame is straight and that the wheels are centered in the
frame.

Scroll down to the bottom and read "The String Method."
