I forgetted. Dry ice on the OUTSIDE not inside. That could also create an over expansion incident which will result in injury or death...

I have watched many Youtube videos. I'm not interested using air pressure. I may try a bent metal bar and see if I can push them back out. That or see if i can get a stud gun or someone to pull them.
Thanks,
Ken

The tank is one of the first things people look at. It makes or breaks the look of the bike. Yeah I know, looks don't make it run any better, it does show how well it is taken care of. Says a lot about the owner too. My bike has been different colors in the past 40 years. Always came back to blue. It was a Rat bike for a while and still ran like a raped ape.

I had to do something to stop the rust so I decided to to paint it even if it wasn't a "pro" job. This is what I have so far.
can't get picture to load will try again tomorrow
Getting a 505 error, added pic to my profile.

Perhaps I should have bolded, CAPITALIZED underlined and italicized the "USE MINIMAL PRESSURE" and added do not exceed 5 psi. I probably should also clarify when I say "heat" I'm not talking a hair dryer. I'm talking a torch and glowing orange metal. With the dent area heated, minimal air pressure will push it out nice and evenly. I may not have emphasize the safety aspects as much as I should have.
Improper tool use or excessive force of any kind can result in death or injury. I personally had to investigate the death of a mechanic who was changing a truck tire. The split rim blew apart at 90 psi, killing him instantly. On the other hand, the air system in my garage is set to 120 psi and I had a Nitrogen tank that I charged rear shocks to 150 psi routinely when I was actively racing. The force of pressurized air needs to be respected, but it's also not instant death. Anyone using it is not automatically a candidate for the Darwin awards. You're not driving around on flat tires are you? If you don't have the equipment , experience and knowledge to do something safely and feel completely comfortable, don't do it.

Hey i tried to say the same thing about air pressure being okay last time this came up.
Got the same result. Yet the 2 strokers say to use it dor expansion chambers.. Go figure. Done it before with an air regulator set to 10psi with a 14psi safety blow-off and woops I'm alive with a few dentless tanks. But hey, what do I know? To each their own.

Instead of compressed air in a can, they also make freeze spray for electronics diagnostics. Much colder than compressed air in a can. Just google it. Lots of suppliers.
I also recall seeing a youtube video where a blood pressure cuff was stuffed in a tank behind a dent and then pumped up to pressure to pop out a dent.

I had a thought, Instead of a stud gun, why can't a i glue a nail etc. to the tank and give it a little pull? The dents are not that deep and it sounds easier than trying to get a bar into it to push it just right?. I'm going to check some of the glues I have and see what may work.

Motorcycle tanks are made out of pretty strong metal; much thicker than modern autobody panels. I've suceeded in ripping studs off and making holes with stud guns before moving the metal, i'm fairly certain glue wouldn't hold long enough to pull a dent

I remove dents from 2 stroke pipes with compressed air and a torch no problem.
HOWEVER, the problem with using that method on a tank is the tank is shaped like an upside down 'U'. When you pressurize the tank it tries to flatten out, basically you'll see a crease form up the center of the tank. You need to support the sides somehow, like temporarily welding straps underneath.
5 psi won't do squat. Been there, done that. And I've seen 2 stroke pipes split from people freezing water in them.
Your best bet is to use a bar from inside or have a shop use a dent puller from outside. I tried a Harbor Freight dent puller on a 76 KX tank. There was a crease so it was a pain, but it did work "ok". (I was being gentle trying to save the original paint) You need to use better glue though. There are other more expensive systems you can buy too.
