Jetting for winter?

[killed300ex]

I recently just bought a lt 250r i know its not a honda but hey its all i could get and i got a great deal. Anyways i need to rejet it because it is next to imposible to start but it runs good once i get it started. I am wondering do i jet it down or up for winter? BTW some of the mods are a full fmf pipe bored 60 over on a new rebuild not sure what is in it now for a jet but i plan on doing it tom and am looking for some advise. Thanks

in winter months, you will need to go a size or two larger on the jets. this is given it was jetted right in the summer. for easier starting i would make sure plug was new. also, make sure your slow jet is big enough.
