Hard to start SV650

My SV has had a hard time starting, lately. The battery seems fine, but I have to fully choke it for about a minute or it won't stay running on it's own. After that, it's fine.

I bought some carb cleaner, but I haven't had time to tear the bike down and get to the carbs to spray them out yet.

Is there anything else I should be looking for?

That seems to happen when the temperature gets cooler. Are you sure you need to go through all that.

Full choke for a minute doesn't sound like a problem, especially if it runs fine after that.

YA THINK???

Yeah I would have to agree... run it full choke for 2 mins... if it's cold that is parf the coarse.

Didn't N4S have this problem and he got them cleaned and sync'ed???

So try full choke for 2 mins and see if it runs good after that.

As long as it starts with the choke and it runs fine at normal operating temperature, you probably don't have a problem.

Rarely is the question stupid, but sometimes the answer is you need to run everything you read online through your own personal BS meter to determine if it makes sense to you.

My CBR uses Keihin carbs. Cleaned them many times, but not the choke plungers. The carbs have to be separated from each other and I don't want to do that. Here's how I clean them.

I turn my gas tank petcock to off when I come down the alley to my garage. The engine dies after a few minutes, and I let it cool down. The fuel line and float chambers are now dry. I disconnect the fuel line from the tank and pour carb cleaner into the line using a funnel until the float chambers and line are full. Then I connect the line back to the tank.

With the engine cool, I put the choke on full and start it. The carb cleaner from the float chamber and fuel line is running through the choke plungers and passageways. After a few minutes, fuel is running through the clean choke system. Not as good as taking the carbs apart from each other, but a lot less stripped screw heads.
