Is not the stock Yuasa an AGM battery, like the Odyssey?
The Odyssey is nice color though, eh?
If it's not staying lit on full choke, I suspect the choke cable needs adjusting. Mine certainly doesn't like to drive anywhere until it'll at least barely idle off choke, but it lights up nicely even when the air is below freezing. It won't idle at 1400 even with the choke right off.
