Your link is excellent! Shows everything you need to know and shows how similar the systems are for the 300i series of scooters through 2013! Shows the connector I was asking about which is the same as mine. The only difference is the earlier machines used either a PDA or a laptop to read the ECU. The Kymc tool simplified all that. I have no new ideas right now.
Hi Karl, thank you for trying to brainstorm, what is going on... Also for being such a trusting person, it is rather rare nowadays. I charged the battery overnight just to rule out a weak battery - I used the bike only for short distances but was cranking it a lot, primed, and so on. I am rather happy to report, that a fully charged battery jumped the bike straight away, so the throttle body cleaning by the mechanic must have done the trick
Now that high idle is the next to tackle
Does anybody has got any experience with the air idle bypass valve? I have read, that could cause idle issues...
Thank you,
Have a nice spring day...
