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.
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 :)
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 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
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
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
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 :)
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
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??
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!
@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 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.
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.
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
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:(
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 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.
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
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.
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.
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.
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
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.
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?
if it's not too bad, like no scratch inside the dent, that it would be possible to just fill it with clearcoat to prevent the light from bouncing in the curve and show the dent ?
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.
