Some additional info to the above euphonius post:

On my 3km ride to meet him, I had 2 stalls. One of which was going thru a busy Shanghai intersection and was unable to do a quick "thumb start" to get my ass out of the crosshairs of numerous taxis, cars and other motorized vehicles. After getting safely to the street corner I thumbed the starter a few more times and finally the bike fired up. It was another 200m to the motoshop where I met euphonius (who was getting a forkjob - no comment!).

Fast forward 30mins, I turned my bike over to euphonius to compare his post-serviced forks with my Chongqing stock forks (fyi his frontend is tight now with minimal dive). Euphonius thumbed and thumbed the starter, but my bike would not fire up. I tried a few times unsuccessfully, then decided to turn the throttle wide up for a full second, and let off it quickly. And guess what? She fired right up without a cough. Not sure what this was about, but initially it seemed as though the battery didn't have enough life to start the bike - but after a twist of the wrist there was no sign of electrical strain whatsoever.

After a great lunch at 小杨生煎 (Small Yang's Fried Dumplings) we took off for a quick jet to Jiangsu and back on 沪太路 (Hutai Lu). Total stalls I had upon reaching the border of Jiangsu was 18. This included both DOWNSHIFTING STALLS and IDLE STALLS (idle stalls are what I describe as stalls which occur when idling- e.g. sitting at red light). When we got to the seawall that runs along the East China Sea in 浏河 (Liu He), my bike wasn't stalling at all.

Based on what has been discussed by all of us in this thread, I will guess that these first 18 stalls occurred when the bike was on the "less hot" side of life. By the time we got to Jiangsu the bike had increased in temperature and was then running HOT. With all the variables the ECU was trying to map, this was a place she was most comfortable, calculating correctly for RPMs, Engine Temp & Ambient Temp. Note: As the bike became hotter upon reaching Liu He, the ambient temperature had dropped quite a bit, creating a greater contrast between engine temp and outside temp.

(Incidentally I need to buy a winter riding jacket, otherwise I should plan to only ride in Southern China these next few months!)

* The battery discussion is an interesting one. I've had some core electrical issues with my bike early on which prompted me to install the new battery. Then, I had a stator issue on my Inner Mongolia Ride (click to see details on this). I am volunteering myself as the first to change-out the battery - this will be a "fix in isolation", meaning all other things will be kept constant - including color of my socks.

Is there a recommended battery someone can suggest?
