I have a 2007 GS500 that I did a carb rebuild on. The bike starts perfectly (cold or hot), goes to a high idle with the choke, and settles down to a nice idle once the choke isn't needed any longer. I find until the bike is FULLY warmed, there is a bog or hesitations upon throttle tip in under load (started from a stop). Once rolling and cruising down the road at 2,500 rpm or higher, it runs excellent. Once the bike is FULLY warm after about 10-15 minutes of riding, the bog/hesitation is gone, and it runs excellently through the whole rev range, even from a stop.
I am not very experienced with tuning carbs, so I was wondering if there was a good area I should start to help with the cold-blooded nature of the bike. I do need to balance the carbs still, so maybe that is contributing?
Thanks in advance for any recommendations.
Our GS's are a little cold blooded, yesterday mine stalled twice trying to pull out of the garage after warming it up for 5 minutes. Just use more revs.

This is normal, don't worry about it. These bikes seem to take a bit longer to fully warm up than some others.
Sounds like you did a good job on your carb rebuild!
