Choke issues, opinions?

So the other day when I took her out, it was mid-30's outside. First time I've tried starting in that cold of weather. She cranked just fine and caught, but died immediately. It took me about 10 short starts/dies before the engine would stay running, even on full choke.

Yesterday I took her outside (upper 30's or low 40's) and same deal - multiple repetitions of crank/die. Before I got her running completely, I pulled a plug on both cylinders to ensure there was no fouling or anything else. What I noticed was that the rear cylinder plug was wet, the front was dry. Tells me that the enrichment piston on the front carb isn't letting any (or enough) fuel in, causing this issue. Both choke pistons move freely.

I looked at the carbs and the exploded view and it's going to be an everloving pain in the neck to pull the choke plunger on the bike. Anyone have any other ideas before I pull the carbs? Can you pull the plunger on the bike? Can you even clean the passages?

Here is a link to Roach`s carb rebuild thread with accompanying videos on Youtube:

It has been awhile since I watched this video, and I don`t recall exactly what he covers, but it should help you.

The carbs have to come out to get to the choke plungers. But the diagram is scarier than the actual carbs. and yes you can clean the choke orifaces.
