Modern Vespa

My toilet at the moment - having just finished one.

The photo in your pic was taken last year so how can it be at the moment ?

I, too, have dropped a duece.

i'm having this problem too!! have u managed to solve it? they changed a new set of ignition system and CDI. the problem still persists.

Well on my last brand new 2012 GTS 125 which i just sold i had the spark plug (CR8EKB), plug cap, HT lead and coil changed under warranty to try sort it and it still came right back..I have a feeling it's bad batch of regulators or injectors..??? Time will tell as i am sure piaggio will find the issue at some point.

i dont think piaggio here is knowledgeable to solve it. what can i tell them to check in order to solve it asap. i dont wish to put my bike into the workshop again

Hope I'm not treading on any toes here, but on the GTS forum a member says that REEDSPEED scooters UK seem to have found the problem. The forum member says he thinks they said the regulator is at fault. Apparently dealers are being informed.

Are they??

Hope so

Hope this helps.

Bugsy.,

I know Reedspeed have been looking at the problem (they are local to me) and they are a decent dealer, so fingers crossed.

Here is my experience for the record. After 620 km I experienced engine cut out on my 2012 300ie GTS.

Engine stall ONLY occurred from idle.

I brought it to my mechanic after reading the forums and he determined two different issues:

First, he tested kill switch. Switch would kill the engine, but the engine would start with the kill switch still turned off. He replaced the switch and then it operated fine.

Engine still stalling though...

Secondly, and these are his words.

"Ignition leak found to be cause of fault. High tension wire (spark plug wire) appears to have been torn during assembly. Having the high tension wire connector at the high tension coil exposed has led to arcing of the spark to the frame. This is evident by the melting of the casing of the high tension coil and the above mentioned torn grommet."

I've included a photo of the melted cap. The melted plastic encased the high tension wire and was quickly filed away, tested and worked fine. No more stalling. Warranty item.

Happy to say the Ti-Fighter is back in action! No stalls, no worries.

All is fine now! I hope this info helps someone else.

I am having a similar problem. Mechanic changed air filter, spark plug but now my 300 super sport is sucking down gasoline like crazy!!
Mileage is really low.
Any suggestions as to why it´s using double the gasoline it used to with only 20000miles?
Thank.s

It could well be the ECU spuriously triggering the injector. I can remember Cheekythomas finding one like this a few years ago - he had to hook up an oscilloscope to see the false triggers.

Two years ago I installed this in my GTS with great results. This product is exclusive to SW (and so is the picture). Why not give it a try?
