Re: What is wrong with the 2007 GT?
I got the software upgrade on my K1200GT two days ago. The change was instantly apparent, and clearly for the better (at least from my point of view).
1. The throttle is VERY much smoother; more to my liking. I have to rotate the throttle more than before, but that's okay. Bumps that tweak the throttle don't cause the bike to jerk in a self-exaggerating motion (no more "feedback-loop" on bumpy roads).
2. The jerking and surging (BBS) in low gear at low RPM is significantly reduced, but it is still there somewhat.
3. Engine braking is reduced, but in a good way. It was simply overwhelming before; like giving the brakes a good squeeze. Now, rolling off the throttle yields comfortable, smooth engine braking.
4. Shifting is way smoother, too. It is much easier to accelerate at the green light in a "genteel" way. I can't explain why the gear clunking is reduced, but it is. Because engine breaking is reduced, and throttle control is better, it is easier to set the correct engine RPMs when shifting up or down.
5. The throttle lag (dead spot) around 4,000 RPM is still there, unchanged from before. If you roll on the throttle very hard around 4,000 RPM, there is a quarter-second hesitation before the acceleration kicks in.
6. The bike still has way more power and acceleration than I would ever need. It may take more roll on to get it, and peak power and torque may be reduced. I would gladly trade reduced peak horsepower and torque (especially if it is spread across a wider RPM range) in return for excellent throttle control.
Bottom line: The bike is SO much more rideable and useable than before.
