yeah, sucks that we were one step away from solving it, but I can only imagine working in the freezing cold while sick is no picnic. Sometimes it's better to know when to surrender.

Besides, he's only owned the bike for a week and I'm sure he didn't want to screw it up going down the wrong path following some internet hack.

Perhaps in the future the weather, his health and confidence level of the advice given on this board will improve.

You're right on... as usual.

Been there, done that! The only problem is the water in the bowl. If it's a lot, the engine stops. If only a little, maybe a slight miss. Too much starter fluid and we have other problems, i.e. kind of like the first "pig in space"!

I had a similar problem. I was never not able to turn it over, but It was extremely cold hearted and did not want to idle. I took it back to the Dealer who found that one of the Carbs was clogged. He waranteed it out and it didn't cost me a dime. Runs great now. I went back for the first service and have just put the first 1,000 miles on it.

This bike is great. Fun good looking and not scary.

No start, check for spark by removing spark plug with spark plug wire connected then crank it over. Good spark means good ignition, no spark means bad ignition.
Next spray starter fluid into the carburetor (with air filter removed) then crank (10-15 sec.). if it starts and run for a few seconds then the carb/fuel supply isn' supplying fuel. Check fuel flow, if ok then its clogged jets. If not then the fuel source is bad (no fuel flow to carb). If those don't do it, then most likely no compression, or ign. timing is way off (this would be indicated by backfiring and/or extremely rough running and lots of black smoke). One other item would be a safety lockout switch not operating or bad sensor. If these don't help then take two Advil and call a professional in the morning.
All ignition combustion engines operate on the same principals, but there are literally thousands of configurations, and someone that is familiar with your engine would be the most help with a hard to troubleshoot problem.
By the way ethanol has an octane rating of 115, and will mix with water, and gas, this is why Dry gas works.
