Had a quick look at the rest of the wiring last night. Nothing obvious out of place. Power up resistor still resisting, replaced main fuse, cleaned connections at TPS and ECU. Since fixing the melted mess of stator/power wires near the rectifier, it does start better with no back fire or popping yet, and it hasn't threatened to stall again. At the recommendation of another friend, I may invest in some dyno time to play with the CO settings. I can check WOT and dial in the upper numbers, and also get some a/f data at steady cruise where it feels like it's not running smoothly. Or, I may just ride it. 2000km trip coming up, leaving Thursday. It does run really well under load Scooter, if it's accelerating at all, or high speed cruising like you mention, it's fine.
Going to get it on a dyno when I get back. Check my CO settings for proper A/F and power output, and get some A/F ratio data under the part throttle cruise conditions where I have the concerns.
Did you ever get this sorted? I just picked up a TE630 with similar mods/jd tuner and having the same issues at lower rpms.
[quote = "pilsner, post: 616838, member: 64593"] Avez-vous déjà eu ce tri? Je viens de prendre un TE630 avec des mods similaires / accordeur jd et ayant les mêmes problèmes à des rpms inférieur. [/ Citation] before i had the same problem, today without Jd and with ebat settings ( recommanded Dynobob), it's Really better !!!
