Modern Vespa

Hi guys

Do you warm your Vespa up in the morning? DO you let it run for a minute or so?

I noticed this morning that I started my Vespa LX50, got on it after about 20 seconds and pulled away from the house. THe bike sped off but the revs sort of paused for about 2 seconds at approx 15mph and then it just continued accelarating as normal, and I didnt have any further problems along my 20 min journey...

Coud this be because I didnt let it run for a few mins?

IMHO you got it right.

I let mine warm up for a min or so...no worries.
On occasion I have left before giving it a moment, and something just doesnt feel right for a short time.

I let mine warm up for a few minutes. Start it them put my helmet on and gather my things. I do find it rides better (at first).

I have stalling/pausing issues with my (carbureted) LX150 if I don't let it warm up for a minute or so. Just start it before putting on helmet and gloves, that's usually enough time. My understanding is that's SOP for carbureted bikes. On fuel-injected bikes this shouldn't be a problem (for them, you want to wait a few seconds for the fuel pump to pressurize after turning on the key, before you start it. Then just go go go).

My 150 which is fuel injected needs just 20-30 seconds to get up to speed. Anything less will cause some hesitation.

I think the carbed LX'S need it the most IMHO. My little guy will make me warm him up.

I've come across this as well and still have it. Think it's related to the glazed clutch bell, but what do I know? The problem goes away after a minute or two of riding from a cold start.

You may have something there. My MP3 has only stalled twice, but both times it has been within a few hundred yards of starting off.
