Hi Guys,
I have been having some battery/starting issues lately with the weather here in Canada getting colder

well there's your problem right there -- Canada -- it just gets too cold too quickly here!

As usual when it's cold it didn't start right up and I had to hold the starter down for a while before it really started firing well.

this is totally normal.

I ran it gently for a few km's and then after warming up some more the problem seemed to go away.

normal until the bike is warm

Everything was fine until I hit around 4.5K rpm's and it started to miss/backfire . . . I tried to start moving again and the backfiring/misses started again.  

a theme coming here . . . normal for us Canucks

I have discovered [ymmv] . . . that once we hit the middle of September it takes a lot more time for my bike to warm up. full choke to start, easing off gently until it is fully off [been told that driving with the choke on will foul the plugs] and RPMs at ~1500 . . . then I'm usually good to go.

should say I'm riding an 80 CBK, same mileage [unless there's a "1" at the front that the odo didn't catch
