Hi Guys,
I have been having some battery/starting issues lately with the weather here in Canada getting colder so I put my battery on a tender last night and was able to start my bike up this morning.

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.

Anyways, I let it warm up the usual amount and pulled away.  Everything was fine until I hit around 4.5K rpm's and it started to miss/backfire.  I pulled over with it still running to see if there was anything I could see visually and tried revving the engine when it was out of gear to try to replicate the problem.  With the bike in neutral there was no backfiring/missing so I tried to start moving again and the backfiring/misses started again.  I ran it gently for a few km's and then after warming up some more the problem seemed to go away.

Is this normal?  Should I be worried and need to take immediate action to fix the issue (e.g. clean carbs etc)?

I was planning on working on the bike throughout the winter and wanted to use the time that I have left to ride.
