55/158 jetting with stock pipe?

gasoline or gasohoil (10% ethanol) in your area? (fuel blend may change in winter)

Make sure the enrichment slide moves freely (the slide in the carb at the end of the 'choke' cable)

Mine was terrible to start also,even with the mods. As the temp got colder the bike got just about impossible to start. Then I bought the mikuni from XRs only set up for the bike and I can only say that it has been transformed performance wise and winter starting wise. I would say it was the best investment to the bike that I have made. This is the nonpumper model.

How long in between is it typically? Do you turn off the gas petcock when you park it?

It is the W rating that is important in the cold. The 20W in the 20W-50 is what makes the oil thick around freezing, not the 50. 20W will make it about unstartable below freezing. 15W will get you down to 20 and 10W will take you down to colder than I can even imagine getting on a bike. I use the 15W-40 Rotella and it works OK down to a cold as I ever plan on riding.

Stick a bottle of 20W-50 in the freezer. It's amazing how thick it gets.

I've gotten into the habit of shutting off the petcock and letting it stall each day when I get home. By the time I remove my helmet, open the gate and walk it to it's crib it's just about dry.

I allways thought carbs were better off left wet than dry.

That would only matter if the bike is left outside, or the garage also sees temps that low.

stock pipe and gasoline 92 octane 55/158 . choke seems to be working fine would going up a size on the pilot help?

55/158 should be fine.
make sure you don't have an ill-fitting boot or a dislodged vacuum line giving you a vacuum leak.

Try this- before turning on the petcock, drain the bowl (until empty) with the screw at the bottom of the carb, leave it open, turn on the petcock, and close the screw when fuel comes out.

Some gas additives can go stale really quick, but if you're talking about starting the bike every day (instead of once a week or so) its probably not that.

Once you do get it started, does it idle well?
Could be a little junk on the pilot jet, or if you have the long pilot jet maybe the slosh baffle is giving you grief.

I have an 03 with the same issues. Its hard to start 50 or below. Crank it a few times then let it sit for 30 seconds, then it fires right up. I'm running a 55 pilot. I've also noticed the oil pump noise till it warms up again. (left during the summer).
