The 'choke' on the WR actually 'adds' fuel, - Clark is this correct? You may be way lean on the FS w/o the choke, but able to run with the choke engaged. Just an idea.
It sounds like there have been some performance mods done the bike - removed air box lid, removed exhaust baffle. The carb may be way too lean for the mods & weather conditions.
My '99 would not start w/stock 45 PJ after I removed the air box lid. I backed out the FS a 1/4 turn at a time and it would start/run better & better the more turns out. Once I put in the 48 PJ it would actuall start & run.

I had the same problem with an old gs400, was just dirt in all the carb. Look at the jetting, you should see the jet's number on the jets and post the datas, it could answer some questions.
Thank for the info (Brian) on the pj without air cover, my mechanic had some problem to find the problem, this will be a good clue for him.
