Does your pretty new pipe have a dent in it? You can either buy a new one, pay someone to get it fixed, OR…… you can fix it yourself. You don’t even need tools or equipment. In fact, this repair can be so cheap that it’s Free. UVVRPEKQ57ZN
Take the head pipe (header) off the bike and clean it up so there’s no dirt or grime stuck to it. (Usually just a few bolts to take pull it off)
Take the pipe and fill it with water. You should only have to put in enough to cover the dent, plus a little bit more.
Put the head pipe in the freezer standing up so that the water is still covering the dent and won’t run out. There’s no need to cover either end of the pipe.
It will take several hours to complete, so if you throw in the freezer before you go to bed it will be done when you wake up!
Do not, I repeat, DO NOT attempt to do this on a two-stroke or stepped head pipe (powerbomb/megabomb type header). Your risk of cracking the pipe is much higher, and it will NOT be my fault. I also am not responsible for what happens to your straight head pipe if it breaks. You are doing this at your own risk, as this is not the best way to do repair a pipe. I only suggest this if you’re in a jam, or don’t absolutely need the pipe…
With that said, if you have a rather large dent in your non-stepped four-stroke head-pipe, I suggest starting out with smaller amounts of water instead of trying to pop it out all at once. It will reduce the chances of your pipe cracking. Good luck, and have fun riding!
