Hey Guys,

I just recently purchase my GZ from a guy. While he was waiting for the title to come to him so he could sell it to me someone bumped into the bike and knocked it over. They put a dent on the left side of the tank. I was wondering if someone might have the same tank here. My bike is a 2000. I'll post a picture of my bike so you can see it.

If you can't find a tank (and new ones are very expensive) you may be able to find a shop where they can dent it out.
Congratulations on your new bike and ride safe !

I tend to forget about that. Body shops can do absolute miracles with magnet dent-pullers. Depending on exactly where it is located and how deep it is, they might be able to pop it back out like new. Certainly worth stopping at a shop or three!!

I've tried a few different places. They all say it really wouldn't look right being pulled out. The dent is pretty deep. It almost looks like it fell over on a bar. It is creased at the top and bottom of the dent. I thought about waiting until the tank is empty, then shutting off the gas cock. then I could try to plug the gas fill hole with a rubber plug, and try to pressurize the tank with compressed air. I am leary because I don't want to pop a seam on the tank. Anyone ever try this?

BAD idea. And what makes you think it would be any more effective than having the body shop pop it out?

I heard about it from a local motorcycle shop. I'm figuring that it will oprobably just be best to try to replace the tank. I was planning on keepin an eye out on E-bay. There was one a few weeks ago just like mine with a BIN of $145.00. I figure a body shop will charge at least that or more to fix and repaint the tank.

My tank has a dent in the left side from the previous owner. I had a friend-of-a-friend tell me to remove the tank, drain, fill it with water, and put it in the freezer. The expansion of the water supposedly will push the dent out.

I'm too scared to try it.

I think we should take a poll. It seems like quite a few of us have left-side gas tank dents.

I would try the frozen water before I would try applying air pressure to it. Air might cause a weak spot in the seam to separate and might even cause bodily harm. The frozen water is a much gentler process and I feel you could keep a watchfull eye on things while it is going on. air pressure and sheet metal=possibility of shrapnel.

I did the air thing 30 years ago with a dirt bike tank. The tank was dented where I had crashed and my knee bent in the tank.
After the air trick it looked like a basketball. The sides are much weaker than the seams and the dent would probable be one of the hardest parts now.

Short story, I don't think this will take out a dent.

:plus1: :plus1: . I have to 100% agree with that, and I don't think filling it with water and freezing it is going to work either, even if either one of these ideas does pop out the dent, I think it is going to swell in places that you don't want it to as well as where you do.

Why try to get rid of the dent? A VERY old trick (that we used to use on car bodywork) is to get rid of the paint , in & around the dent, (scraper, glasspaper etc) then fill in the dent with a 2 part filler such as "plastic padding" or even fibreglass. When it's set solid, shape it with a sander, then paint it. Might take you longer, but it's sure cheaper. We learned all these sort of things in the days when money was tight, and before the era of "built in obsolescence" :2tup:

There are all kinds of tools a good body shop uses to PUSH out these kinds of dents. There is another method that is used - heat up the area with a hair dryer, then spray it with a cold spray can (like the compressed air to clean electrical components), or apply a piece of ice, to rapidly cool it, and sometimes the dent will just pop back out as the metal contracts.
Search the net for dent removal or go on You tube, you'll find these, and it doesn't mess up the paint at all.
