Moin, does someone happen to have a sym jetz Euro 50 X Built 00 – 05 with 45km/h registration? My son has been driving the scooter for 2 years and since he now has the driver’s license with accompanied driving, he is also allowed to drive scooters with 45km/h. We wanted to upgrade the scooter, but unfortunately we don’t get any information if this is possible and if so, how. To make it clear: this is not about illegal tunes, I’m talking about a legal upgrade. Problem is simple: TÜV has the registration original customers of both The 45s version also has more power, so the engine has to be throttled. Sanyang doesn’t move anything out, points out the dealers. The dealers also don’t want anything out, want more money than the scooter is worth for the conversion… 🙁 What I know for sure so far: it’s NOT throttled over the CDI! Even the Vario-Matik-Rings alone don’t do anything, since the engine then runs out of the “pust” over gauf e.g. I have already made various searches for the type approvals, but only Dutch pages come up and there it is allowed on 45km/ – is really milking to the mouse… Must be somehow possible without that cost 500€?!? So if someone has such a scooter with official 45s approval, I would be grateful for a contact, possibly offline.
