That blood pressure thing is just genius.....this 7 year old video is one of those that people are probably still going to be referencing in 7 years from now.....so cool, thx dude

The McGuyver of tank repair. Thanks man, I took a nasty spill and you just saved me $800 for a new tank

Cool ideas. I’ve seen a few folks try the heat and cool method but haven’t seen it work. The hammer trick and the cuff was genius

Sweet! Thanks! The blood pressure cuff is a great idea! Definitely going to try that as well.

looks like my 93 year old mums blood pressure pump is going to go missing ,lol

"Gonna take this bikes blood pressure" hahaha

Great video. I would have never thought the BP cuff would have actually worked.I'm going to try the glue and hammer handle one for my dent. Thanks again.

Rapid taps at stretched metal peaks with a plastic hammer while inflating/pulling glued implement helps inverted/dent to pop out and metal memory is locked back in close to original :)

Love the BP cuff idea... great vid man. inside that tank looks a lil rusty!

This is the most underrate video haha. Loved it

You are a genius Max! The Motorcycle Doctor is in....next appointment please :p)

Any of these methods alone will do the job. This was just a demonstration of the 4 techniques that I use. Oh, and teaching someone a new skill is never a waste of time

Like that blood pressure cuff method, nice work 👍

Thanks for the ideas dude!

Brilliant vid, thanks very much for taking the trouble to post it.

I had a similar baseball sized "wop" in my tank. Used a wood dowel as a puller with hot glue on the end. Stuck it to the tank and gave it a quick yank. Took 5 tries but it did pull the dent out to where it was barely noticeable.

came looking for a trick- you gave me four. Boss.

This video is full of awesomeness! I'm going to try this on an identical dent on my v star.

You totally rock, dude!

Good video, as always.

I hear ya man, its not the bondo that I mind so much, its the prep, sanding, waiting, painting, etc

Awesome Stuff Max. Get that Garmin suction cup while they last lol. GPS is soon all going to be just a simple app on your cell phone.

Race drag cars in a class (outlaw pro radial) that does not allow wheelie bars so we often dent/crush headers. I use a similar technique where I cap and pressurize the tube to about 30 psi and heat the dent with a torch, by carefully working the flame along the crease in the same manner you would doing hammer and dolly work you can repair even the worst of dents to a like new condition.If doing a gas tank with a torch I would try C02 on a gas tank as you sure would not want to use anything that supports combustion LOL

I got the dent out of a 1980 Z250A tank by using the sucker from my satnav cradle i attached it to the middle of the dent and pulled........pop good as new :)

Great info!

one way we did it once was to fill the tank with water and freeze it but you have to have the cap closed and you need to keep an eye on it or it can burst your tank open, and that will work only with single walled tanks.

Great video!! enjoyed it clever ideas!!

Might work, I liked the bp cuff though because it was basically a square shape and expanded relatively predictably. It would suck to be pumping and pumping on an inner tube only to find it bust open the seam on the other side of the tank

as always Max your a fricken Genius, I am going to try this but I have a bicycle inner tuber I'm going to try, my dint is much lighter than yours on this tank so I will let you know. just wondering if I should do the hot air and compressed air whilst the tube is in and pop it out whilst the air is still defrosting, I'm sure it will work, thanks again

After seeing this video, my suggestion is that I would have used method 1 and 4 together. Heat/Freeze with the BP cuff already in place. Thanks for the tricks!

Can you do a guide on painting? I've done a bit of it myself using spraycans and I think that I may have started to get the hang of it, but any hints are really useful. Do you know anything about using proper spraypainting gear (compressed air, paint guns, etc)? It would be interesting to see differences/opinions on whether it's worth it for painting a bike. Love your work, it's a great inspiration!!

Close of the gas valve fitting. Make sure any vent tubes are capped air tight. Fill the tank with water. To the top. Close the gas cap. Freeze. Keep checking on it periodically. The water will freeze. Expand and push the dents out.

(Finishes spraying coolant) "Cool"

great video ...i used the blood pressure cuff...it works the best...i think a thin rubber band wrapped around it to get it in the tank works best

Yea its a good little trick, I havent had any luck at all on creased dent, but it will be pretty effective on lots of uncreased dents

@mrmaxstorey they actually make dent pullers that are pretty cheap on amazon.

Nice trrick with the blood pressure pump :)

you forgot one method that I use is to build a fuel cap that excepts a air valve like you use in a tire blow the tank with air should hold 120lbs then take a hammer and tap around the edges of the dent and the air will pop it out in most cases

That hot glue gun + hammer trick worked like a god damn charm.

I wonder if filling it with some water and then putting dry ice in then gas cap back on would work.

what is the product you're using for the cooling effect? "compressed air"

Thank you very much.

Thanks have a Bultaco tank will try heating with hairdryer but no spray so try a block of ice or a old deodorant spray then last resort hammer as spraying tank so needs sanding

Air bladder plus heat and ice. Super dent fixer

Nice video. Wish you showed plan C how does it work. Glue it and then.... is it just ripping it off or slowly pulling it, etc...

If it is too close to the fill hole you might be SOL, maybe a little bit of bending and pocking out form the inside can get it better. If it is not connected to the hole then you might be able to bondo it, as featured in my cb550 video

What about dry ice with a lil water (to get the gas process started) inside the tank...when done just bleed off pressure through petcock before opening main tank cap. Should work I think...just a thought.

Good when you know what your doing!

The tank has a hump in it that runs up the middle so it can hug the neck of the frame, the bp cuff pushed off of that

Thanks for the dent popping video! I will try this when I get home from work. I have a question unrelated to the gas tank though. On my 80 SR250, I'm trying to do a quick oil change; but I can't seem to find the drainage area. I've been trying to download manuals for a little bit and not having any luck. Can you help??

you can use a slab of dry ice and leave it on for a while... they do that on thick car doors, it should work with this.

I have a dent similar to the one you showed on your bike ( the other bike with the creased dent in the corner ). I'd like to see how you get that out.

Awesome! I've been a body an paint man for along time an have used these tricks. Anything to get out of spreading bondo. Lol

I wonder if you jb weld something to the dent and pulled if that would also work

@theknivjocke Unfortunately I dont have the resources to paint. I just spray can it if the bike is a rat bike, or sand/primer it if the bike is nicer and get a friend to paint it professionally

@canfaller Right on ive done that with exhaust pipes, id be too worried about bursting the seams of a tank tho

You'll probably have a harder time with exhausts, they are usually harder steel. But give it a shot, can't hurt

They also sell inflatable bags for locksmiths in different sizes that operate likeca blood pressure cuff. For some reason i never thought to use the one i have for this😂.

What was the first spray can stuff that froze it..? The blood pressure thing might work for me too..thanks

hi, great vid btw, very helpful How exactly did the blood pressure cuff work? did it fill the entire tank and push the dent out? or is the tank divided into a half so its easier to push out? thanks

Resealing the fuel tank required? Dent caused by the bike tipping on trailer. Rounded bar put an elongated dent in side of tank.

I think that the BP pump + the hair dryer would have been the quickest.

Use the British method . Step 1 : This would be to neatly cut 1 or 2 holes in the under side of the gas tank about the size of a regular business card . The holes of course would be directly in line with the dented area . Step 2 : Next , go into the tank via the holes that were cut and using flat faced punches tap out the dents . Step 3 : Next drill up to 4 holes at the corners of the piece that was cut out . Step 4 : Next, screw in sheet metal screws approximately half way into those holes . The screws will be used to push or pull on for positioning purposes during final brazing . Step 5 : Next , support the gas tank on your work bench with the hole side facing upward and fill the tank with water as far as you can go . Step 6 : Next , hold each screw by finger or with tools to help position the piece back in place while brazing all around the perimeter . Step 7 : Remove the sheet metal screws and braze over the holes . Step 8 : Use files or power tools to shape the brazed areas to the desired contour . Step 9 : When all brazing repairs are finished turn the tank right side up and fill 3/4 or more with water . View all the brazed areas closely for leaks . Wah La ! Your gas tank is now repaired ! Any minor imperfections on the outside of the tank can be easily repaired with automotive body filler .

Thanks man!

I use high temp hot glue, and the big end of a drumstick. The BP cuff trick is great though $10 at walgreens will have to try it...hopefully never ;)

@TheFawawa Dude that's genius

Haha I have no idea. Each of these techniques should be able to get out this dent on their own, I was really just trying to demonstrate them all on the same dent. Never thought of combining them however, next time I'll give it a shot.

They are really rare, last one I saw for sale was like $7000 I guess you could find them cheaper, but I just never see them

@TheFawawa Yeah Ive seen em, probably should get one someday if I ever need to pop a dent from a tank I am not intending to paint

Not required if the tank was not punctured, if it was use POR15 for very small pinholes.

TANK you!!!

great bike

what if the i have a pretty bad dent next to the gas cap in my 83 nighthawk...what do you think would be the best route to take?

If the crease is sharp, sometimes all you can do is fill it in and repaint

Go for it

i have a dent right near the neck of the tank, not very deep, barely noticeable, which method do you suggest?

I actually used the garmin gps suction cup to my kz440's tank with just one pull my dent came right out.

Dude I just put a dent in my 2020 slim any advice on fixing this before I get reemed a new one from the shop to fix???? Any tips?

have a 2004 Honda Hornet 599 do you think any of these will work

Next time I dump my bike I'll make sure the dents are in a perfect place.

Hmm as I recall its just a big ole plug on the bottom of the engine... im going to send you a link to a PDF for your manual

Hi there, I enjoy your video, then I wondered

cool tip thanks

use compressed air, plug gas tank filer hole, and petcock with meatl and rubber using exsisting nutplated located inside tank. After heating the whole tank up in the summer sun, apply heat to dent area, then fill gas tank with compressed air until the dent pops out. Careful not to over inflate tank and blow seams apart.

what technique can U use if the dent has creases around it and it's along the rounded parts of the tank? I had an accident on my 2007 Triumph Rocket 3 this past September and I don't want to spend $800 $1100 for new tank.

Max, what if you would have reverse the procedure, by tis I mean, insert the presure bag in the tank, then heat the gas tank and then spray with that cold air.

POR15 is meant to be used to line gas tanks

If you put the cuff in, then heat the dent and use de can of air?

I got a 1971 Suzuki TS 90. The dent is right over the bolt on Suzuki decal. I think I can only fix it with Bondo. What u think? It's a shame too cause it was all original paint. It tipped over on my trailer right when I bought it:(

You can if you want but its not required

What about a innertube ? Like off a 4 wheeler or bike ?

Thanks

I think the best way is to make a cast of the opposite side larger than the dent with a vent tube let it harden .then remove and place over the dent and pull a vacum dont know if it will work.just saying.

i have a yamaha dt 175cc with a dent. its 1992 do think the tank is that old enough?

How small? If they are pinholes you can probably seal them by using POR15 on the inside of the tank. If they are any bigger than that you should probably get it welded if you can find someone who will weld it

hey bro i made two small holes in my tank from a scrow driver how do i fix them plz help me

You can order it offline try ebay

Awesome

What about the Old Toilet Plunger Method? Do you think that would give similar results as the Hammer and the Super Glue? Or how about the Method of drilling several holes in the dent and then screwing in screws part way and then pulling on the screws with a pair of Pliers or Vice Grips? Of course with that method then you would have to repair the holes in the tank that you drilled by Welding or some other method. And Finally - Do you think the Blood Pressure Cuff Method would have worked on your dent from the beginning without using the other methods??? Thanks for posting your video, I enjoyed it.

I couldn't hear what is that spray u used at the beginning, what is that product for? And, what kind of air bomb is able to put inside a gas tank?
