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
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
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.
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??
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
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 :)
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
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.
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!!
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:(
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.
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
@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
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.
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 :)
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
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
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
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!
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.
hm :/ how much does they go for in the us ? i know you can find them for about 1500-2500 dollars here. and you can find dnepr for 400-1500 dollars here.
Hey man, great video! Someone knocked my bike over while it was parked today, which left a small dent on the side of my tank. I've got a 2009 yamaha xv250. You mentioned that these methods work best on older single-walled tanks..do you think any of these tricks would be worth a shot?
How did you get the blood pressure pump in the tank? I understand how it expands and pops the dent out from the inside but how exactly did you go about doing it? Did you try and get it close to where the dent is located or did you leave it at the top?
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
You said if it has the crease from greater impact that the first method wouldn't work.. I have 2 dents on the curve with a crease and really don't want to use a professional.. Which method should I use? I will be sanding and repainting as well
I got a dent on the top part of my 07 V-Strom tank. Do you think the blood pressure method would work? Does the size of the gas tank matter? It's roughly a 5.5gal tank.
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.
hey how come the air didn't simply come out of the opening of the tank? I didn't see anything filling the gap between the blood pressure thing and the rest of the opening.
+ivantoxie The blood pressure cuff is like a thick rubber balloon that I jammed down in the tank. It is not filling the tank with air, just expanding itself inside the tank
So here's an odd one, how did you yank the hammer off? And lastly, how does one find out if the tank is double skinned? because then the bladder wont work, im guessing
Haha ok, wasn't sure one would have enough grunt to pull the dent. Thanks for the reply, I do appreciate it! Regarding the second part, I have a 2010 Ninja 250R, I just hope the tank does not have a double skin because using the blood pressure idea might not have the desired effect. Was asking if there is a way to know if the tank is a double skin so I don't mess up... Either way, this video was the best one I've seen and I'd just like to say thanks!
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.
just curious, i notice the dent is on the right side of the bike, but in the after pictures you are very careful NOT to show the right side of the bike. did the dent not come out?
Starting at 7:46 I showed a side view followed by a lateral view of the final product showing that the surface was pretty smooth and even, for the most part
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😂.
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
It is now 4 years and I just needed to referencing it
@@dirtdog511 im needin this trick today
9 years ago and still referencing the video
9 1/2 years and I just stumbled across this gem. blood pressure cuff is genius
im goin on ebay right now for the blood pressure thing....
The McGuyver of tank repair. Thanks man, I took a nasty spill and you just saved me $800 for a new tank
looks like my 93 year old mums blood pressure pump is going to go missing ,lol
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.
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
"Gonna take this bikes blood pressure" hahaha
what is the product you're using for the cooling effect?
"compressed air"
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.
Stay Thirsty did it work?
Rumor has it that he is still thirst.
I’m sure dehydration has set in by now.
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.

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
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?

i have a dent right near the neck of the tank, not very deep, barely noticeable, which method do you suggest?
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.
Thanks for the ideas dude!
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...
have a 2004 Honda Hornet 599 do you think any of these will work
Like that blood pressure cuff method, nice work 👍
@canfaller Right on ive done that with exhaust pipes, id be too worried about bursting the seams of a tank tho
If you put the cuff in, then heat the dent and use de can of air?
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.

This video is full of awesomeness! I'm going to try this on an identical dent on my v star.
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:(
What about a innertube ? Like off a 4 wheeler or bike ?
I wonder if filling it with some water and then putting dry ice in then gas cap back on would work.
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.
i have a yamaha dt 175cc with a dent. its 1992 do think the tank is that old enough?
Love the BP cuff idea... great vid man.
inside that tank looks a lil rusty!
came looking for a trick- you gave me four.
Boss.
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
Does your tank need to be empty for that
***** Yes
Yeah, works great until you can't get the busted rubber band out of the tank.
You are a genius Max! The Motorcycle Doctor is in....next appointment please :p)
I hear ya man, its not the bondo that I mind so much, its the prep, sanding, waiting, painting, etc
Thank you very much.
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.
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
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?
I wonder if you jb weld something to the dent and pulled if that would also work
Great info!
@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
This is the most underrate video haha. Loved it
Great video!! enjoyed it clever ideas!!

hey bro i made two small holes in my tank from a scrow driver how do i fix them plz help me
(Finishes spraying coolant) "Cool"
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?
The spray is keyboard cleaner. I put a blood pressure cuff inside the gas tank.
@mrmaxstorey they actually make dent pullers that are pretty cheap on amazon.
You totally rock, dude!
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

Good video, as always.
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
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!
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.
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.
what kind of compressed air did you use?
it was keyboard cleaner
You got any Honda parts for a cb 750.
hm :/ how much does they go for in the us ? i know you can find them for about 1500-2500 dollars here. and you can find dnepr for 400-1500 dollars here.
Brilliant vid, thanks very much for taking the trouble to post it.
Hey man, great video!
Someone knocked my bike over while it was parked today, which left a small dent on the side of my tank. I've got a 2009 yamaha xv250. You mentioned that these methods work best on older single-walled tanks..do you think any of these tricks would be worth a shot?
Ingrid G-M Sure go for it
+Ingrid G-M Did you try it? Did it work for you? my bike got knocked over too and got a tiny ding in it.
How did you get the blood pressure pump in the tank? I understand how it expands and pops the dent out from the inside but how exactly did you go about doing it? Did you try and get it close to where the dent is located or did you leave it at the top?
I rolled it up and sent it down thru the top opening, down the side to where the dent is
@@mrmaxstoreydoesn’t the cuff shrink and not expand though? I don’t get it. 1956 BMW R26 has a little dent on top and getting after it.
@@TreuNorthExplorers the cuff blows up like a balloon and pops the dent out
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

If you will be sanding and repainting, then just fill the holes with bondo and sand smooth
Thank you!!
Thanks
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
I got a dent on the top part of my 07 V-Strom tank. Do you think the blood pressure method would work? Does the size of the gas tank matter? It's roughly a 5.5gal tank.
Give it a shot
max, what can i do about a dent that looks very similar to "your" bike, the one that you said you probably couldnt use you the heat/compressed air on?
You can fill it with body filler and repaint
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.
Nice trrick with the blood pressure pump :)
That hot glue gun + hammer trick worked like a god damn charm.
hey how come the air didn't simply come out of the opening of the tank? I didn't see anything filling the gap between the blood pressure thing and the rest of the opening.
+ivantoxie The blood pressure cuff is like a thick rubber balloon that I jammed down in the tank. It is not filling the tank with air, just expanding itself inside the tank
@Mrmaxstorey doesn’t the cuff shrink and not expand though?
Thanks man!
Resealing the fuel tank required? Dent caused by the bike tipping on trailer. Rounded bar put an elongated dent in side of tank.
@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
cool tip thanks
TANK you!!!
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
So here's an odd one, how did you yank the hammer off? And lastly, how does one find out if the tank is double skinned? because then the bladder wont work, im guessing
Umm, just yanked on it? Im not sure I understand the question. And really only modern sportbikes have double walled tanks, I'd just try and google it
Haha ok, wasn't sure one would have enough grunt to pull the dent. Thanks for the reply, I do appreciate it! Regarding the second part, I have a 2010 Ninja 250R, I just hope the tank does not have a double skin because using the blood pressure idea might not have the desired effect. Was asking if there is a way to know if the tank is a double skin so I don't mess up... Either way, this video was the best one I've seen and I'd just like to say thanks!
Maybe?
Air bladder plus heat and ice.
Super dent fixer
great bike
Is the blood pressure pump ruined after this?
Not unless it rips
@TheFawawa Dude that's genius
What years do you consider older?
Before 95, I guess.
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.
I just bought a 78 Kawasaki kz400 and need a few parts.
Where can I got to get them?
ebay, the kz400 forum, or bikebandit.com
Thank you.
just curious, i notice the dent is on the right side of the bike, but in the after pictures you are very careful NOT to show the right side of the bike. did the dent not come out?
Starting at 7:46 I showed a side view followed by a lateral view of the final product showing that the surface was pretty smooth and even, for the most part
mrmaxstorey ok thanks for the reply. it was just a real quick flash, and kind of shaky. i was hoping to see what you had done with it after.
You'll probably have a harder time with exhausts, they are usually harder steel. But give it a shot, can't hurt
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.
Awesome
@dropfry Awesome
I think that the BP pump + the hair dryer would have been the quickest.
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😂.
Did you have to heat the tank with the hair dryer before it worked with the BP Cuff?
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
Go for it
