My rebel only runs with choke on

Usually, I needed to turn on the choke for some time in order to warm up the engine.
But right now after winter time I started riding the bike again and even after 30 minutes of running, the engine shuts off when I turn off the choke.
What could the problem which prevents the warmed up engine to run normally with the choke off?

Sounds like slow jet needs cleaned.

Welcome. ^^^What shakeedogg said. Have you installed an inline fuel filter? It's cheap insurance that any contaminants in the tank or fuel don't reach the carb and mess it up.

Keepin' all the left over parts. Gonna use 'em to build another bike!

Thanks, No I haven't installed an inline fuel filter, I bought used bike 1.5 years ago and it ran great but after the winter this problem started. I have been fueling it with the most expensive gas though, but looks like it didn't help.
Looks like I would need to clean the carb.

In the meantime, I will be riding it with the choke on.
Is there any disadvantage of running the bike with the choke on?

Using the fuel enricher to compensate for the restricted slow jet shouldn't hurt it. You're just augmenting what the jet does. I'd install an inline filter sooner rather than later. this is what I use. Many auto parts stores carry them. https://www.amazon.com/Visu-Filter-I...068296&sr=1-14

Expensive gas just costs more; doesn't improve performance.

Got it.
Is there any way to clean the slow jet without disassembling the carb?
Also, I am wondering for how much time approximately it would be safe to ride with the choke on while the slow jet is clogged?
I've been reading that when riding with the choke on the spark plug may be damaged, but curious if I have at least a month when I can ride the bike with the choke ON or whether the carb should be cleaned right away?

In theory, you could do it by removing the float bowl, if you could see the jet and had hands as small as a baby. AFAIK, it's never been done, and would probably take a lot longer than just removing the carb.

True, but "expensive gas" around here means premium (i.e., no ethanol) which definitely has advantages.

Which are?

Ethanol free gas is available locally in all three octanes. I used to put 87 octane non-ethanol in my Rebel, and IIRC, it cost around 30-40 cents per gallon more. Non-ethanol fuel might make sense if the bike wasn't ridden enough to burn a tank every three months or so. But I usually run through a tank twice a week or more, so there's no chance of the ethanol gas going bad. I get the same mileage and top speed with either type of gas.

Higher octane gasolines are designed to be used in engines (usually high performance engines) that "knock" (self ignition) with lower octane fuel. It doesn't produce better mileage, more power, or harm the engine so long as the proper octane is used.

Yes, I'm well aware of everything you've stated.

Where I live, ethanol-free gas is only available in "premium" grade, not all grades. And the advantage of ethanol-free gas - independent of performance, knock issues, etc. - has been discussed numerous times elsewhere (e.g., less corrosive on rubber parts, etc.).

I never stated there's any advantage to performance, etc. Let's not try to start a spat when there's no reason to do so...I actually don't see any disagreement between us.
