Tried the "header in the freezer" trick to fix a couple dents that I had. It worked great! :bonk:

That's impressive ... What year/type bike is it for? ... Did you have to plug it at all or just go with a couple inches of water past the dents?

Did your wife actually let you put that dirty, rusty pipe in HER freezer? :bonk:

That looks great. How long did you leave it in the freezer?

It's off my '02 426. I didn't plug it, just put enough water in to go a few inches past the dents and left it in overnight.

I'm not married, but I did tell my daughter "If you open the freezer and see an exhaust pipe in there, it's normal". She rolled her eyes and replied "Yeah, normal for this house". Lol...

Wow, I hope it works as well on my '07. My dent is nearly identical.

Fantastic! I thought they would have need to be capped to keep the water in the tube... This makes fixing the gnarly pipe on my daughters RM worth while. Oh yeah I have a freezer in the garage!

I'm guessing that the water freezes on the ends first and creates it's own plug. I'll bet that on a 2T pipe it will work exceptionally well due to the conical shape of the expansion chamber...although the 2T pipes are a heavier gauge material. I'm going to freeze the stocker from my YZ250 next.

I'm going to try it on my YZ250 pipe tonight. It's already of my bike. How long should I let it freeze?

I just did my header overnight, but if you are doing a two-stroke pipe it will take longer to freeze hard since it will hold much more water...I don't know for sure, maybe 12 hours? :bonk:

I'll let you know tomorrow if overnight works.:bonk:

I've read that it's good to check it every few hours and take it out when it fully 'popped' back or risk splitting it if the water/ice expands too much.

How come when I tried this it didn't work? :bonk: I have two small dings in the header of my 06, I wonder if the smaller ones are harder to get back out for some reason...

Kind of reminds me the last time I had the whole family over to the house for a BBQ. My sister opened the freezer to get ice. She pulled out a crank and a lower triple out of the freezer started laughing and said what the &*() is this.... The wife laughed and said my buddies bike was in peices in the garage and it some how migrated and ended up on top of the peas and carrots that I use as a ice pack....


Tell ya, everyone just started laughing and both brother-in-laws and nephew gave me high fives.....I just told the siter it could have been worse, if she had been at the house the day before she would have caught me with a fresh jug that I was cleaning in the sink...


I get away with this shit though, I do most of the cooking and cleaning around the house, so it is almost impossible for the wife to even raise an eyebrow. besides, I came in the house a few day's before that and there was a coffee can full of keorosene on the counter with her poi in it.....:bonk:

Pin point dings are indeed more difficult to pop back out. Larger dents offer the ice more areas to push on, and less likelihood that the pressure of the freeze can push out toward the ends of the tube instead.
