Got an 06 r6 and it has been pulling to the right lately to the point where I got to lean my body to the left just to keep it going straight. I checked psi and it was fine and it was not windy. Thought it might be the road but it consistently pulls right on any road. The one thing I found is if i run my finger across the tread of the tires i feel a raised bump running along the tread of the tires. Don't know if that could be affecting it, other than that the tires look fine.
