Is that something one should do? I was always told (on car engines, albeit) that running without an exhaust is very bad.

Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Don't run without an exhaust. You'll burn your valves.
I have had coils go bad so that they shorted out when hot. They would work fine for about a half hour, then the bike would quit.
You said that last year it ran OK for 45 min. but this year it doesn't, right?
Your bogging symptoms certainly sound like carbs with non functioning pilot circuits. If choke helps, that confirms it. How are you cleaning them? The pilot circuit comes from themain jet, the brass air jet in the eir horn, the pilot jet, the air screw, and two ports by the butterfly. There are lots of internal passages in the pilot circuit. If you hate to separate the carbs from the rack, like I do, thak the air screw, pilot jet, and air jet out and clean them. Look through them. Spray carb cleaner into the ports these came out of and confirm that it comes out of all the other ports. Reassemble replacing the two O rings in the pilot circuit.

Number 4 is too rich. I doubt that the smoke you see in your airbox is exhaust. It is most likely from your crankcase. Do you have a hose attached to your airbox that comes from the top of the valve cover? Have you cleaned out that hose or taken off the cover from where it hooks up?
Looks to me like you need to address why #4 is rich. My guess would be carb adjustment or bad spark plug wire/boot.
