I've had that issue in the past, but as the years and miles have went by, both ways "feel" pretty much the same.
Have you tried to speed up? Changed your expectations of how your riding? As a rule you don't loose the skill you have developed to that point, but attempt to move up in some way and surpass the current skill level, bringing on the new problem.
Running wide is never good, no matter which way your turning. And running wide is seldom brought on by actually going to fast, most of the time it is a pure and simple result of target fixation. Target fixation in a turn, IMO, is bought on by allowing yourself to align your line of vision with the front of your bike in a corner. If your looking through the corner (in a left for example, looking around the corner to the left of your bike) you will seldom have problems holding the needed line. If you shorten your line of sight up to look directly (or almost directly) over the front of your bike (at the edge of the road on the outside of the left hand corner), your screwed. That's when you start having problems holding a line, running wide, turning in too much, getting caught out and feeling uncomfortable turning the bike in general. Rights are shorter, blinder, more in and out affairs that cause you to focus more on the "event horizon' to the right of your bike and the edge of your available line of sight. Lefts are longer, more open, and require you to hold the line longer, giving you more time to allow your vision to swing back and fixate over the front of your bike, giving you the left turn problems. Keeping this from happening just takes seat time and mental focus, and the faster you go the more this comes into play.
Riding a motorcycle is sooo much a mental game. Relaxing on the bike, (even somewhat) proper body position, good line of sight practice, can all go a long way toward stopping any strange "feel" issues you may be having, and allow you to move along to a new level in your ability (and hopefully leaving the problems you were having behind).
