How-To: Fix a Dented Two-Stroke Pipe

[mbrick]

Pressurized with 100+psi of air, a torch, and no safety glasses. I too like to live dangerously!

[wesleybickel]

I marveled at all the flammable degreasers and paint propping up the pipe as he heated it up glowing red

[milioo]

I guess he is a very skilled mechanic and knows what hes doing. Personally I would use some sort of protection, because I would hate have a glowing hot metal balloon popping in my face.

[michaelwendler]

Good thing he has glasses protecting the top of his head!

Flame on - check .
Glasses off - check .
Job done - check, glasses on.
Safety third - check . Lol

I've done this with water. Fill up the pipe with as much water as you can get into it and stick it in the freezer, no caps are necessary. If the first freeze doesn't get the dents out simply let the water melt and do it again. It's really cool how it works and way easier.

150 psi? What? Everyone else uses 60 psi but I must admit this is the best finished product I’ve seen

[tomthompson]

thought i was the last person actually doing this, .. nice to see im not alone, I was taught how to do this thirty years ago by a trials bike rider.

[davidofqwerty]

Been doing this for years and have never needed to use heat like this, just the kit to block the pipe and a jet wash, always looks perfect

I’ve filled a gas tank with water, creamed a raw potatoe in the filler and stuck the tank in the freezer. Got the dents out of my tank. Could do the same, maybe, with the expansion chamber - if your freezer is big enough. Great trick. Thanks for sharing.

I used to just fill my pipe with water and freeze it for a few days the ice expanding would pop all my dings out.

Mick is a Legend, knows his stuff, ex racer and bike mechanic took some big dents out of my sherco 300 pipe yesterday, came up like new. But yeah I know of people who tried to do it themselves and blew out the pipe so only get it done by someone who knows what they are doing.

Had my FMF pipe fixed this way. If you don't your shiny pipe being heavily discolored from the flame, it's a great method. If I had a 2 stroke ever again, I'd get a non-nickel finish to avoid this and I don't care for shiny pipes.

The "Clamps" are just split bearing pullers, available everywhere! Easy to fab the plates

Some inexperienced person has probably died trying to do this.

I have tried the freezer trick, fill up with water, make sure the low area with the dint is at the bottom of the water lever.put in big chest freezer, then watch, I check every 5 minutes once it’s close to freezing.
And with big dints you need to let it melt, a bit to fill the dint depression then freeze again.

I was at Farleigh castle back in 82 as I lived next ti the track. It’s still there and still has memories. Noyce, Thorpe and so many others I filmed there back in 2010.

I wonder how much the pressure increases with the heat, and decreases with the metal un-denting. Be interesting to put a gauge on it.

My HERO! Safety consultants steer clear away from his part of the country!

[John-jrqi]

I do this kind of stuff all the time. I like to keep my aerosol cans closer to the action though.
