Scooter dying in cold weather?

[zukinjo]

Hi all,
I am new to the whole "scooter thing", I've bought Agility 50 a month ago and it was running ok (slower then most of you are reporting, but still...). For the last couple of days strange things started to happen. The only difference is that the outside temperature has dropped to around 32-35 F.
The scooter starts normally, and when I apply the throttle easily everything is ok. But if I apply the full throttle from a standstill (which I usually did) the engine just dies. I tried it this morning for a couple of times and always the same. Changed after a 10 minute drive, became less sensitive to the immediate full throttle, so it has to do something with the temperature (even thought I never start driving immediately, I always leave the scooter on for at least 2 minutes to warm up a bit).

And it is really struggling when it's fully stopped (traffic lights, for example), but I guess that's normal for the cold weather...

Anyone has any thoughts or similar experiences?

Hi tortoise, thanks for the link. I have read it already and I understand that the temperature influences the performance. But mine just dies... I must admit that usually I read a lot of posts before asking a question but this time I didn't do it thoroughly...

The topic from this link (that I haven't found previously) solves my worries, and this whole thread can be deleted... Sorry guys

Long, and short of it is... Cold air is denser, and it creates a lean running condition in the cylinder.
There are two solutions. Re jet 1-2 sizes larger (richer) in the winter months, and or go 1-2 steps colder on the sparkplug. (up in numbers)

We just hit 30* here today, and my bike can't leave the driveway under it's own power. It will warm up by Friday so I have no worries.
