Have you tired checking the steering stem/tree by sitting still with the bike upright and turning the bars left to right? No binding going on? Check your clutch line/cable, throttle cables, front brake line for clearance in case they're not free enough to allow your bars to turn lock to lock. When you're riding the bike, it's nature is to be upright and going straight from centrifugal forces of the wheels spinning....so turning the bike would need countersteer input to lean and initiate a turn. If things check out sitting stagnant, keep riding to get more comfortable.
