On another scooter forum, there is widespread opinion that the evaporative systems on the Piaggio and Vespa scooters can be very dangerous. Some have said that in the midst of riding at highway speeds, they can lose power and the engine cuts off. Something about the evaporative system not working well, and never having worked well before. So there are strong opinions that the evaporative system should be removed from the scooter before it causes problems like stalling on the highway.
My question is that for people on this forum, have your experiences with the evaporative system on your Piaggio scooter been that bad? I have a BV 250 brand new with only several hundred miles on it and haven't yet experienced anything negative with the evap system but don't know if I will when I go on a long trip during the summer.
