You're probably 'hanging' on the inside bar, ie- using the bars to hang onto the bike with and what this does is countet-steer the bike in the opposite direction which will push it to the outside of the turn rather than continue on its path around the corner.
Try this instead - when you hang off, lock your outside leg onto the bike (the cut-out on the tank, heel-plate) and don't cross up your body position (sit close to the tank and 'twist round' it), only half an arse cheek should be off the seat. Relax your grip on the bars and don't apply pressure to the bars except to turn the bike in.
That way you're only holding onto the bike with 3/4 of your backside and your outside leg, rather than applying needless input to the bars while cranked over.
You only need to pull back on the inside bar when you roll-on the gas to bring the bike up out of the turn.
Or, you could be rolling off the throttle while leant over which will then increase the contact patch of the front tyre and 'push' the bike to the outside of the turn.
This is a double edged sword as not only will it make you run wide, but will reduce ground clearance (which will make your knee touch the ground easier) but more importantly deck-out part of the bike or worse. Oh, and overload the front tyre which could result in a front end washout.
Don't believe me? Ask Keith Code.
