Hey, I hav a Vespa ET2 that is just back from the shop where they replaced the exhaust and removed the limiter.
Now after about 10-15 mins of riding the bike wants to cut out when I am stopped at the lights and I have to do some careful juggling with the throttle to keep it alive.
Sometimes it cuts out altogether but will usually restart the first few times.
If I have been using it for more than 20 mins and it cuts out I have to leave it off for about 10 mins before it will start again.
I dont think its an idle problem as when its on the sand the rear wheel is just turning slightly.
This problem was not there before it went into the shop...
