We were doing that in the 1980's as we all had 2 Strokes!! 😂 a oxy/acy torch works best..you gotta use what you got but if your doing something you need proper equipment...don't over inflate it as they BURST ...sharp dents/creases can be taken out too... just takes a different technique..only the big dents matter in fact...the small creases are not worth dealing with...use pipe guards to save your pipe too...
I made one of them in 1986 been doing that for 30 years.Every aftermarket shop did that .It is a money maker .There's a kit that uses pressured water with no heat and a hand water pump. Don't give up all your secrets.
Went to buy one of these kits a few months back, changed my mind and brought it to a shop. Got the pipe home and noticed the shop burned a whole through the pipe! Was pissed should have didbit myself. Good Job
Learning to do it yourself is the best option...you can do it cheaper at hime and save time too... we did this ourselves...i raced in 70's to 90's and everyone did this themselves...
Thanks for the review! I am going to send you some longer bolts and another muffler end gasket. That CR250 setup did look sketchy. We include longer bolts when we know the setup is for a CR250 or RM250 so the clamps on the muffler end can be put below the mounting tang. Much safer and the clamp will fit the pipe correctly as well. Pipes turned out great. Good job.
I've done plenty of them with that kit it works but extremely dangerous using that much pressure but got to do it I always worry if it will blow or not ive seen tires blow with 30 psi only is no joke
Metal and sealed high psi with a heated pipe... if it bursts that's like a grenade going off. I fill my dented pipes up with water and cap the ends then I'll put it in a big freezer for a day or two and it has fixed the majority of damage on my chambers.
if you cheap you just need some radiator tube, jubillee clips and a shrader vale and can make this at home, ive tested radiator and oil coolers that i had brazed with similar idea
You can buy expanding rubber plugs used for plumbing that seal the ends and one has the valve in it...like this setup..we made ours too back then..having it grab from other side seals better and it doesn't BLOW OUT VIOLENTLY... safety people... we used truck mudflap for rubber but any thick material works... they made these back in 80's for sale too were about $100 then..so most made cheaper ones at home..lol
We made our own pressure tools to do this back in 2 Stroke World....i started with DOWNPIPES...😂 Dents were Common back then.... Build a Pipe guard..too...simple stuff for us 2 Strokers....you kids !! 😉
Gary Mallard pipe guards actually make the pipe bend out of shape more easily it saves dents but will make the entire pipe bend when hit hard or dropped to the left , I took off my pipe guard for that reason rather have little dents than a header that touches the frame it’s so bent
I've always been told you should use water instead of air because the air will make it explode more if it bursts. Using a pressure washer works good too I've seen.
You should actually wash as much oil as you can from inside of the pipe first, the amount of pressure you were using can split seams, use caution in those areas, the heat marks will polish out of the nickle finish with some cutting compound and a buffer, dents that are closer to the smaller area after the manifold will have the greatest affect on performance, small dents in the larger chamber portion of the pipe have no real affect on performance they just look bad, if the pipe becomes distorted where it doesn't fit right or won't seal at the manifold then it has to be replaced.
the expansion chamber is what MAKES the powercurve on a 2 stroke. it uses resonance and shockwaves in the exhaust gases to supercharge the cylinder. the different shapes of the expansion chambers makes it resonate at different rpms and over different ranges
Yes...the shape changes the powerband on a 2 Stroke depending on how it is shaped and flows...you could get lower grunt..or higher rpm's or more mid-range..etc .. plus look faster too...with a Custom pipe!!...i raced 15 years on 2 Strokes..125 , 250 & 500 classes 2 per year at least...
This is so old. That company you purchased that kit from is a great kit though. I know the owner and inventor of that kit. Love dealing with the locals.
Looking for help with a random question-in the video about pit bikes-I think one of the calipers was frozen and you could identify the replacement pad from a catalog with “ghost” outlines-my daughter’s Chinese side by side needs new pads and I can’t seem to find them anywhere or frankly know where to look-that catalog or supplier I suspect would be really helpful to get her back up and going All the best
thad be cool i tried the ice method one time and it just busted the seams of my fmf and exploded the pipe, but did nothing to my OEM pipe. i ended up brazeing it back together.
Dude what’s happened to your channel, I use to be a huge fan now since you moved it’s like you barley upload and when you do it’s not really interesting. Sucks to see as I watched you all the time and learnt from them when I started out but we wanna see you digging into a 30 year old bike and doing a whole build series but not wasting money or doing budget builds and maybe race them with other budget builds or something along those lines. I really hope you listen because the channel is dying and don’t wanna see you stop uploading like you already have been. It would be sick to do another full build with Adam like that straight rhythm rm250 as that was so fun to watch and even watch it still to this day
Common for a Channel to lose content..then go to simple stuff to try to stay relevant....this is a good tip...but i raced 2 Strokes for 15 years and they showed this in MXA & DIRT BIKE back in the early 80's at least? we already were doing this in the 70's too...i had Downpipes then..lol later we had up pipes and added guards for dent protection....nothing new to some of us..but a good tip for young un's
dents don't really rob power unless they crushed at the header ...what does rob power is carbon build up, try putting the pipe in diluted acid to remove all the carbon in the pipe ,you'll be surprised at how much power you gain .

I used that on my broke to built kx and to my surprise the plating on the platinum pipe polished right up. I was amazed.
I have the exact same thing I bought it off eBay as well and it works awesome! I've used mine alot.
Built one back in the 80's, still have it. It's hydraulic, compresses water. You have to anneal the dents before filling with water, works great.
My first desert race on a 2 stroke and I put a taco size dent in my pipe. Bought a replacement but I'm investing in the tool.

Thanks great should have. Wanted it to be perfect as it was a new pipe on a brand new bike. Boy was I disappointed.
These Kits are a great tool, mine is similar with relief valve. Just Braze the small pin holes.

Awesome! Ive been on the fence about this setup, thanks for the vid!
Works way better with 100psi, little less heating
Need to make more vids ! Been waiting for the next on forever
I know, right?
I cant believe my cycle guru Clint JUST found out about this !!! Finally, something i knew more about !!! 😃👍👍👍👍👍👍👍👍
Most damaged pipes are also misaligned so that they do not fit well in the exhaust port. Does this process correct alignment?
I've always been told you should use water instead of air because the air will make it explode more if it bursts. Using a pressure washer works good too I've seen.
Water dosent compress and hold energy to release if the container fails...air does compress and is like a spring when released all at once
Nice definitely a good money saving tool 🔧
you can easily make one of those for much cheaper than 100 dollars. but looks like it works well

what about the temperament of the pipe will that change and will it dent twice as easy I know it did for some of my stuff
That thing is awesome. I got a ? Does the expansion chamber size an shape really have an effect on high an low end power ?
Very much so

Does it work for chrome silencers
So whatever happened to 722 n 723 do you ever talk to them or see them anymore
Sweet video brother 👍🏻
Tried to do it with freezing water but no dice. Not really wanting to spend 100 bucks on some kit to fix it when I could get a brand new fatty for 278
whats the link
What a find!
the link shows nothing?
my buddy snagged one of those kits so im set for as long as he keeps it lol

You can fix that pipe with a hole..easy welding work..
Already gone
Someone is going to get hurt and it is your fault for not knowing the danger
Just watch the gauge and dont go over like 60psi or melt the metal past just orange/red hot. Worst case it will blow out and make a hole
That’s not black lol
