Lower speed?

No, the Zwiebacksaw doesn’t want to throttle down, it should stay at 25km/h, does not want to stress with the Cheriff’s What bothers me is the high speed (shit automatic) on the straight and mountain down and the associated fuel consumption of around 4 liters/100km. Is there any way to change something on the variomatics? The scooter is also throbbed over electronics, even mountain down I don’t get over the permissible 25km/h. It’s an Alpha Motors Cityleader, Euro4 Injector that according to the importer can not be throttled. And again, I just want to get the speed down, does not want to drive faster! Greeting Mirko
