Hi, I'm looking for any help please with my Vespa GTS super 125 iget 2021, it runs fine for about 10mins but then it starts playing up, it will rev but won't go any faster, for example if I was to slow down and do 10 it would sound like it's chocking when I'm reving but then works again until I slowndown and it happens again this could happen at any speed even when I stop at a junction wont accelerat I have replaced the throttle body, Exhaust Oxygen Lambda Sensor, Ignition Coil and the air filters, but still no joy.

I don't know what the problem is but if you can't figure it out then Paul Leadley in Northampton is your man to fix it.

Feel free to message me for his contact number.
