I'll strongly encourage you to keep the automatic vacuum operated petcock. The 'Air Injection System', you can use your own judgement, as regards time required to servicing valve tappets.
One of the things on my to do list this spring is to swap out the Vacuum Operated petcock... you think I should leave it on there? I Want to be able to drain the gas out of my tank if need be. Also, yesterday was my one year anniversary on the Forum!! hooray.
The Clean Air System is not an Exhaust Gas Recirculation system. What it does is, via a vacuum-operated pump, inject outside air into the exhaust tract in order to promote more complete combustion of waste products.
Other than making it a bit easier to work on the bike and removing a small amount of weight, taking it off of the engine will neither improve nor degrade engine performance. It will make you a bad global citizen and upset Greta horribly.
Wonder . . . what type of emissions reduction equipment Greta had on the two auxiliary engines of the million-dollar racing yacht she sailed to the UN?
Because i do not believe one iota of info on climate change its coming off. I’ll leave petcock. Thanks for help again. Heres a interesting perspective on climate. Sadly this makes more sense than Greta.
I think GWN & T.S. finished answering your questions sufficiently, yes?
But we humans tend to get lazy about turning fuel taps OFF & there is no overflow pipe inside the USA model KLR CVK carburetor float bowls to indicate a leaky float needle before it floods the engine.
I believe that partially flooded engines & hydraulic locking of the piston could be responsible for some of the broken piston ring lands that we have all seen on the internet sites.
Now, about that link, could you re-post it in the Off-Topic Lounge? I'm curious and I probably haven't see it.
No one intended offense to you, cfestings, IMHO! Regarding, "motorcycles," some emission control systems apply. Excuse our, "gallows humor," if you can find forgiveness in your heart.
Wondering how Greta traveled to Davos without a, "carbon footprint." Yet, were I still a student, I'd be willing to cut class Friday for ANY cause! (Cut classes one Tuesday for Mardi Gras, without bias toward or against any krewe.)
Welcome to the forum!

Just remembered . . . we're not going to have ANY internal combustion engines in a few years anyway, right?
When I bought my 2004 Gen 1, I rode it home trying to break it in casually while covering a couple hundred miles. Once home, I took ALL the Calif Crap off the machine. I also got rid of the electrical junk connected to the Sidestand. As years have gone by, the Calif crappy gas plugged up my vacuum operated Fuel Petcock and it quit delivering fuel to my carb. My Vacuum operated petcock is now in the garbage can, being replaced by the wonderful Yamaha petcock. My carb is in pieces right now waiting for my new jet kit to arrive so I can ride my KLR once again. So....... Yes, I took off every single hose that was not needed AND also all the bits and pieces relating to all those hoses. My machine runs very good.... FWIW, I mix my pump gas with aviation 100LL with about 20% AvGas to 80% premium pump gas. The AvGas acts as a stabilizer but it does contain Lead. Do I care? NOT at all.....

I was a flight instructor and used to take AVGAS home from work and put it in all my toys. The bikes loved it but, over time the led did clog up my jets. There's a gas station near me that sells Ethanol free fuel from a pump so that's all I use now. And I agree about the pet-cock. Replacing that thing this spring!
If pulling the pump, what do you do with the air pipe hole next to spark plug? Cut the pipe and put a cap on it?
I'm awaiting parts and sitting here looking at that pump. I've already got a manual petcock, why do I need this nasty thing? Soot at every hose connection.
IT is not a pump. It is simply a vacuum controlled Valve.
One can cut a steel plate, drill a bolt hole, use a dab of RTV on the o-ring and bolt the plate down. Then cap the vacuum nipple IF using oem fuel tap.
I did the petcock internal delete. Works 100% and was free. Cant beat that.
