Some dents can actually increase performance! Motocross Action Mag put a five cm wide and one cm deep dent in a pipe 25cm from the manifold. It’s a vulnerable component on every two-stroke dirt bike, and even reasonably small dents will significantly affect power. Get advice on whether your pipe can be blown back into shape before your two stroke pipe repair, which is a far cheaper option than a replacement pipe. That’s exactly what we did with two of our 2018 KTM and Husqvarna test bikes after they came off second best on a recent ride. Basic protection is a carbon fibre pipe guard. These work well to prevent damage from small to medium hits. There are plenty of brands out there. If you live in the USA, I found the P3 guard worked great on my old RR300, you can see it got a thorough bashing in my incapable hands and the pipe stayed in great shape. Not all dents need hammering, apparently some will come out purely with air pressure and heating for two stroke pipe dents. But Chuck is such an aggressive rider he has put some sharp angles in and gentle hammering will encourage the pipe to come back to its normal shape. Getting bored? Let's go and check out Chuck's house. See the technique required to ‘blow’ a two-stroke pipe back into shape - a fix that costs around $100 in labour. Finally, how can we prevent damaging our pipes? The best solution is become a better rider. Almost none of pro level riders use any pipe protection in the extreme enduros. But we are muppets aren't we? As the video reveals, the combination of custom-made clamps, air pressure, heat, and years of pipe-blowing expertise will miraculously restore your pipe’s original shape and performance in a matter of minutes. Chuck will show us the most effective method you can do with easily sourced parts. But here are some options from the cheapest and easiest, to the most expensive. Oh and before you start, they might be ugly but even big dents may not decrease performance. You might get even more power! So check before you start fixing it. Pause to read this. Before you heat that dent, make sure all flammable residue is out from the pipe, and as much of the carbon as possible. If that pipe explodes and takes out most of the neighbourhood then your dead carcass could wind up on a terrorist suspects list with two stroke pipe dents. So, short of tip-toeing through the bush, how can you avoid the expense of a replacement pipe, which retails for around a hefty $350 (and often more). Music: www.purple-planet.com

As Chuck says in the video, this is only one way to fix dinged pipes. The hydro method is also increasingly popular, and probably safer. ruclips.net/video/F7o-MSOES1M/видео.html
Love this channel, love the videos. And I also hate it - because of this channel and you, Barry, I have now bought myself an enduro bike, I now throw myself around in the woods every weekend and get bruises, I now pour my hard earned money into the petrol tank of the bike. And I now can't wait to do it again every weekend. I have a bunch of friends who do the same. Cheers, mate!
it's very addictive donn, and won't leave track marks on your arm (unless a buddy uses you for traction). 😎
This was fun. I didn’t learn anything but had a few good laughs.
That sign "free range kids" is more effective than "beware of dogs" ... lol
I bent two pipes with carbon guards, used a hydra force blow out kit (fancy version of power washer method) to take dents out and it also straightened the pipes back to very near factory shape. Had to use a bar on one of them but now they both fit properly
Unbolt your pipe, dig a large hole in the backyard, place the pipe in the hole and carefully backfill with dirt removing any air gaps. Mark the spot with an old stick, or draw a map where you buried it. Leave pipe there over winter and forget about it. In springtime, dig it up, clean it up a bit and stick it back on the bike. It'll still be dented, but you'll feel a lot better about it. PLus you will have avoided riding in cold, wet and muddy conditions for about 3 months, bonus.
I stopped using carbon pipe guards for a couple reasons 1 it's easier to fix a dent than a kink in the pipe and 2 they are expensive, I can get a brand new pipe for only $60 more than a pipe guard alone.
I don't no where your getting your pipes from by my last one for my exc200 cost $350
Rocky Mountain ATV/MC FMF Gnarly pipe $215, P3 carbon guard $155.
@@archiehurley1094 I used to work parts in a KTM dealership, oem 2 stroke pipes can be upwards of $500, and the KTM powerparts ones are around $350. But if you go with the same fmf pipe but from a typical supplier (wps, tucker rocky, parts unlimited, or direct from mfg) it costs around $250 and the only difference is it doesn't say "KTM powered by FMF" on it.
Can this method fix the dents in my head?
"Can this method fix the dents in my head?" Yes, but you need more air pressure. 1st, you need to scoop out that useless gray stuff that dirt bikers don't use anyway...it's like first cleaning the carbon out of your pipe.
Personally I use a pipe guard made by hyde. Protects like the metal ones but without the weight. Definitely would recommend
I leave gauge connected to the valve so I can monitor for dangerous pressure rising while heating. Also I first preheat pipe then add pressure. I cover ends with some heavy rugs to slow down any flying parts or bolts. All in all this method works like charm for big dents with large area. Not so easy for small ones, maybe I need to get more powerful torch.
Absolutely loved this video.😂😂😂😂
Thanks Brandon!
The one thing I haven't bashed up yet on my yz250fx. I'm hell on plastics, levers and rims though! 4 stoker a gear hi guy here. Thanks Chuck!
2 stroke mate
This isn't limited to Barry at all, this is said quite a lot. "None of the professionals do this, or Professionals rebuild after every so many hours, etc..." Barry addressed this immediately after but really, it's apples to oranges of what professionals do and what we do if only because we don't have a paid mechanic throwing on parts that we don't pay for.
Last protection is good but if terrain is muddy, is adding 10 kg to your bike pretty fast and need to stop often to get rid of the mud pilled up behind. I'm using one self made from aluminum - 10 mm bars netted together that helps with mud and is very light.
your music there had just a wiff o Doobies "What a fool..." nice tips!!
pressure washer works well. be sure to purge out all the air. Air is compressible, water not so much
Colin furze's pressure washer hack comes to mind.
Yes I have repaired a numberl of them over the years, repairing pipes were a weekly thing in the daze when nearly every bike had a low pipe.
with the help of sewer plugs and a few other misc. things from the Hardware store. creating a back up system that catches the plug if it blows is a good idea too, you really don't want them flying across the yard, Oh yes, do this out side!! I alway begin by burning out the pipe first. Mapps gas is ok but I welding torch works better. be careful not to over heat the pipe, adding more air is not recommended.
I tried the water and freezing one, it pushed the dent out slightly but also changed the bend in the pipe to the point where it wouldn't fit without some persuasion aka a rubber mallet
I see Colin Furze use a pressure washer to get dents out using a similar process.
You have to be careful though because the pressure rises really quickly!
Great video and love the safety Sandals are they the Jesus creeper 3000 with reinforced straps and anti slip sole?
Ive done it successfully but use quite a bit of pressure and flow . does split the odd weld but ends up straight.
Confucius say, "Pipe get bent from stone but Stoner get bent from pipe"
😂
@@crosstrainingenduro Oh Barry, either you're the only one that gets me or I'm just not funny 🙁
the pleasure and the pain of having a bent sense of humour!
Another great video! I have used a similar technique to pull dents but long term your can't beat the heavy aluminium guard as shown in your vid. Mine come from Poland I believe but looks exactly the same.
Keep up the good work!
Small spot welds, 6mm allthread, nuts, washers and a slide hammer handle is another way to do it. Or at least to pull the largest part of dents out.
i would use a pressure washer. it is safe and doesn't convert your exhaust into a "pipe-bomb" lol
USA dudes can get their pipes completely refurbished for about 60$, they realign everything so it fits normally again, and weld if needed, something the home kits can't really do.
im a usa dood and have never heard of this. how and where
I love Hard Enduro hillcrest pipe repair
@@TheHuckHD check out www.fusiononeusa.com I sent them 2 Gnarly and 1 Oem pipe so it was worth the shipping from up north. I had one pipe that would no longer fit, a the others were folded at the header.
I had 2 done at piperepair.com last year, with shipping they end up more like $80 a pipe, but they fix dents and bent necks. I'm thinking of trying a p-tech guard so don't have to send out a couple pipes a year. as noted fusion one is the other.
I have the Ballard's offroad stainless steel pipe and it is strong AF, don't even use a carbon guard on it and i've bashed it around, no dints yet after 12 months.
len bong it gave a little more mid to top, when I got mine it was around the same price as the other pipes $380aud and came with a free set of t-bars👍🏻
need to remake this video and use a 'plumbers pump'. can buy it as a kit for about $125euro. using them here in nz a lot!
$125euro??
Ballard makes a very tough pipe
Anytime gases are sealed inside a thin metal container whose halves are held together by a weld, and heated so the pressure goes up...... watch out 🙃 especially if that gas may contain gasoline and oil vapors.
Using water pressure is much safer than using air. Rig a pressure washer, fill with water.
Free range kids can stop a pipe plug real well, no need for rags or duct tape.....😅
A super cheap way to fix it is to plug one end and put a hose in the other so it’s tight and turn that bitch up and bang it will pop out
More like.. This is absolutely the best way to pop out dented pipes! Make sure to wear flip flops in case you gotta run faster than your average tenny runner when it grenades in your face.
funny thing is i completely forgot to ask him which WAS the best way in his opinion....
@@crosstrainingenduro I've actually used his method and, if you're cautious, it works well for steel/s.s. pipes. Titanium - that idk?
Waiting for Wang Fuk Choo the famous tire maker to start making rip off pipes.
Fill with water, place in chest freezer. Dont leave in too long
i got neighbour to fix mine be the thing ripped in half and i still rode around for weeks🤐🤐
Like noise insurance.
I don't think you can melt Unobtainium with a small torch.
This is a true statement now my friend. Most pipes are completely unavailable :-(
115psi and a Oxy propane get it really hot not that weak ass ciggy lighter
115psi and you are holding a bomb haha
why fix it if same will happen tomorrow :)
so true!
why even mount a pipe, if you damage it every day? :)
@@Bike-Breakers that's a valid point, you'd save weight and labor. We don't want to scary squirrels though.
i aint repairing my power dent

Why use air when you can use water? Any hydraulic will work, most simple is using pump from pump-jack.
i'm curious. i have some old bottle jacks, can you explain a bit more?
@@TheCharillz23 look up hydroforming
@@TheCharillz23 Mark is right, hydroforming will explain it better.
About bottle-jack - you just need pump part from it, with wielding you attach fitting on "out", provide water on "in", seal exhaust (like on video), fill it with water, connect pump and pump slowly.
Bottle-jack pump is better then pressure washer because it provides more control, you can pump it slowly and see if all works fine. But any high pressure pump should work
Simple ... ride a 4T !
Prevention is the best method.
