I know this is a forum for cars, but people here always seem to know good tricks. So I thought I'd ask.

I got a Virago 250 recently. Yesterday, I noticed a dent on the Gas Tank, which I know wasn't there when I bought it! I think someone was in the garage and dropped something on it accidentally.

The bike looks great otherwise, but this dent really annoys me. I know in the grand scheme of things, 1 little dent isn't a big deal.

However, what's the best way to Remove the Dent? More importantly what's the best way to do this inexpensively? I've heard of people using Hair Dryers and pushing dents out. Will that work? Any other tricks people know of?

I'm not the body man, but do some research on hail damage repair techniques. They have the tools to do this type of repair from inside of doors and other non accessible areas.
I agree you can look in your yellow pages under automotive paint-less dent repair and see if they can push the dent out from the inside these guys can do magic and requires no paint work

Take it off drain it fill with water and freeze it. Depending on where the dent is you do not need to fill to the top and LEAVE the cap off!
We've done several but you need to be careful, don't split the tank.
I've seen this method on some motorcycle forums. It seems like people get into more trouble doing this, than fixing their Tanks dents.

The dent is so small I don't think it would it would make a big difference. It's also very near the filler cap. So I'm thinking this is something I could tackle myself. I'm trying to learn Body-Work anyway, so this is good practice for me.

you can make a tool to reach in and push it out or you can use a stud puller ( boom ! ). i have an assortment of tools i've made over the years for scooter tanks. bike tanks are thick and all the snake oil tricks i've ever heard of do not work.

DONT DO IT !!!! :nono:
If the ding is that small and bothers you that much ,I would go to a highly recomended dentless repair company.it'll be much cheaper and you'll be much happier with the results...
try something you dont really care so much about for a first attempt at body & paint work....like something that'll will only get better and not ruined,this work takes time and patience to learn...

Ride that bike it's almost summertime.

Rogaine is a rip off....

If you ever hear how some guy used a firecracker inside the tank to pop out a dent, obviously, do not do it. Not only will the dent not be removed, but the chances are good for a fuel-air explosion to occur, sending shrapnel far and wide.
That gives me an idea.....
Instead of making an air nipple adapter at the fuel outlet,tightening the cap and gradually incressing the air pressure while tapping the high spot...

Get some fuse ,drill a hole in the cap,insert fuse ,epoxy fuse to cap, attach M-80,screw cap on ...TIGHT.....light it and run.......hehehe
Get a Harley .... :thumbup: :thumbup:

I don't see it either,,,use the "paint" program or whatever on your computer to circle it in the pic'....

go get a putty and paint "only" estimate from a local body shop...
(you do the grunt work sanding and deliver just the tank to be mudded repaired and painted)...

kind of silly to buy all the supplies needed to fix just a single "ding"

Where's Waldo?

Its hard to see, but ...is that the dent where the reflection of the handlebars go all curvy over to the right of the gas filler?? If so, it's just about the same spot as one I have on my bike. Mine got there when my helmet fell off the right mirror (where I had hung it carelessly!). Could that have been the cause of yours?? I've had my dent for a couple of years now...the bike (Honda 750 Shadow A.C.E.) is otherwise pretty unmarred. I got used to it, though.

if it were me, i would make tank safe enought to work on with open flame. electro stud the middle, use flame in mid of dent only and feather heat out to edge of dip. (center to be hotter than out laying dip) NOT TO CHERRY...but just hot enough to make more pliable than surrounding metal. you may need to use some clay to act as a heat sync around area. next slow but firm, tap out with slid hammer with stud.

Or fill with filler :p

I bought my VTX1800 in 2001..two months later I came out from a store on a trip and there was a dent on my new bike. I was sick..
A fellow came up to me and told me some guy was looking at the bike..talking on his cell phone and dropped it on the tank..and took off.
The VTX being the first year..there were no spare tanks..
I was going to try paintless dent buster..but they did not want to try it..

I tried an old myth..dry ice

I was desperate as any bike guy with a new black bike with a quarter sized dent.

Summer here in Tucson..July. 110*+...
I bought a pound or two..had the bike in the sun all morning. I checked the dry ice using it on an old truck..then my daily to make sure it wouldn't remove paint.

I started on the VTX. I worked the ice for about a half hour..then got some liquid refreshment. I was pissed it wasn't working..I was hot..and wanted to try one last time.

I started again..having trouble finding where to put the ice. When for reading glasses..still having trouble..UH..it worked..

I still have a pin dent..sharp dents won't come out. The pushed in part did..and I really don't notice now..and it will be 9 years this July.

I would not ever have believed this..but it did improve the dent so I don't notice..and I notice stuff on my bikes..
