i came across a used "GDASH" pipe on craigslist. picked it up. the intent was to hack it up and install it on my chinarelli GTX but this pipe looks better than the the JAD pipe's transitions. the inlet port is smaller as well so i suspect this is a 72cc pipe. pipe as posted on CL.  i wire wheeled it with a 4-1/2" grinder with knotted stainless wire cup.   i think im going to measure it up and have the Guru run the #'s on the pipe. I know a Hawaiian cat named Jah who owns one of these pipes. He loves it for his 70cc builds, it sounds pretty good too. I think it performs really well too. |

Following this thread. Was always curious to chop up a pipe and see whats in there. I have a PG long I was planning on doing a 'flip cone' mod on but have to get a couple bikes running and off my property before I tackle that.

so i posted this in my Ningbo GTX build thread, but this is for the DIO guys that come to check out this dd50 engine build thread. i hacked up the JAD pipe in preparation to run it on a minarelli engine. i just figured i would share this stuff for the members, the lurkers, and the visitors. 49ccscoot is the place to be! you might as well join the forum and be a part of it. this thread has over 7,600 views and all it is, is an engine build, no bike, just engine only. it amazes me that this thread was viewed this may times. but this is 49ccscoot and we share knowledge here, we are a community and we support each other, we are a collective think tank. so all you "visitors" and Lurkers out there, take a few minutes to sign up and join the forum.  if not, it's okay. i'm a minarelli guy and this DIO stuff is just for fun. ...like hackin' up a brand new $400 JAD exhaust, for fun (and to learn and share).        |

I have a PG long I was planning on doing a 'flip cone' mod on but have to get a couple bikes running and off my property before I tackle that. Since the JAD pipe is now cut into 3 pieces, it forces my hand to buy a wire feed welder. When that time comes, i am thinking of buying and hacking a PG Long and doing the flip-cone modification. Like you, i have always wanted to see the guts on a PG Long. |

Please study the different welding processes before buying a cheap wire feed welder..They are the bottom of the barrel!Lots of of HF start TIG machines for a little more than the wire stuff,gotta source an Argon bottle though,,Yes and Amico seem to work well for the price,Oxy/Acetylene welding is my favorite form for pipe work,more bottles to fill though..Or do a nice fit up and find a welder dude to sew it up for a 12 pack!! |

thank you for your input 190mech . i was still stuck in 2005 when i was 26 years old, forcing myself to learn how to weld because i wanted to turbocharge my 92 accord and i wanted to do it all by myself. borrowed a neighbor's wire feed Lincoln. in the process, my x-wife wanted driveway gates so i welded up 2 sliding gates. several months after the gates were done, i got slapped with some divorce paperwork, such is life.
Harbor Freight dont exist in Hawaii and they dont ship here too so HF is not an option.
i did end up looking into the Amico stuff. neat stuff and reasonable prices. i see what you mean about "other machines for a little more than the wire stuff". i am learning.
oxy/acetyline... whew. the only time i did that was in high school back in 95 in jewelry class. soldering silver jewelry pieces.
i seen some YESWELDER machines on Amazon for reasonable price. i was looking at the 110/220 arc tig machine. what is your thought on that sort of machine.
thank you for your input. this whole time, i never new that there were lower cost TIG machines. ...been stuck in 2005 as far as welding, especially self learning on a MIG machine that was running flux-core wire because my neighbor did not have the gas set-up for the machine.
**just realize that i know a former professional welder but he is in project management now. used to be a newclear welder several years ago. he has a TIG machine.**

When I wrote "HF",that meant High Frequency Start..Brent has some YesWelder stuff and has done some vids on them too!
Bet your buddy still has a TIG machine,oughta give him a ring and see if he can sew it up for you..

My good friend/fabricator general oh that lives a block up for me is a full on welder I asked him the other night why don't we get into building custom thing custom scooter pipes for hondas and such but at a better quality than obetter quality than what's available and his answer was get get me the proper welder and the proper materials and and no problem he thinks that it won't be cost effective To put down the overhead for all the needed supplies But if if we had such a welder .I'm sure between the 3 of us we could turn a nice profit over here in Hawaii and offer some tigwelled beauties that are only seen in overseas Europe. |

If you produced enough pipes, with some nice variety. I bet it would sell well. many people would love to buy 'USA MADE' performance exhausts for there dios, I am certain.

If you decide to DIY weld it, consider the YesWelder TIG-205DS or maybe something similar. $~280 regular price, and then you need a tank, but if you get a flux core setup and try to weld thin pipes, you will wish you got the TIG. I'm a lousy welder, but even I managed to weld on a pipe a little and not ruin it being pretty new to TIG. I've made a mess of pipes trying to repair them before with flux core. Pipes vary though. At least check wall thickness. I think they say 22ga is OK with 0.030" wire, but I've never found it to be much fun. In a perfect world, I'd never weld less than 16ga (~0.060") with FCAW and 22 is something like 0.030". I have tried HF start TIG and lift TIG and I would go for the HF start, especially at the price that you can now get it at. Full disclosure, this is a referral link. Code 49CCSCOOT is good for 10% off, but currently they're doing Black Friday 20%off. My vid about it is below. yeswelder.com/?ref=4td7cmg2rcyoutu.be/1jQ_G3xdVCM |

as far a TIG i had no clue of HF start and lift TIG, so thank you for your input and recommendation on the HF start.
i am leaning more toward the TIG machines this time around.

i see where you are coming from 808ministroke . but then it only really becomes worth it if it is like a pass-time or a hobby. to do it for full-on profit is too intensive. for real kine, mo betta have it made in Philippines or Thailand. i guy from the shipyard told me that labor is cheap there and people can fabricate.
like what 190mech asked, how much is your time worth.
and by the way, we already figured out the solution for a high quality pipe for the DIOs. and that is the C16 for zuma vert. at $260 for what you get compared to JAD, Scorpion, Sparrow, AP Magic, or even the TWH pipes, it is the best bang for the buck. QUALITY all around and it's a beauty.
if you want to fill a niche of quality exhaust for DIO, maybe a copy of the C20/C21 for DIO. yasuni dont make a C20 for zuma vert. if they did, i would have bought that instead of the C16 and i would have ported the Taida 50mm to the same timings as the unused Polini Evo2 bore that i have and run the 2 ring Taida piston as a single ring.
another way to fill a niche, you sell a bore kit and pipe combo. you make DIO pipe to the same spec as the Polini Evo pipe for the zuma vert. you combine that with the "bombproof" and venerated Polini Corsa, ported to Evo timings. Hammah! i have read of people taking Corsa up to 425*. you could also cheap out and go with the Contessa but you gonna have to do heavy porting. plus too, i have a feeling the pistons are different. SSS got Contessa piston for $82 and Corsa piston for $99. is the price difference due the the chrome rings on the Corsa? or is it a better quality piston and that is why people have taken Corsas to over 400* with no ill effects?
or since you are an MHR guy, you can make a MHR pipe copy for DIO. mate that to a ported MHR Replica, port the MHR Rep to MHR timings. SSS got MHR zuma vert pipes for $370. slip flange and spring like the Yasuni C16 so it can be accommodated the same way as the C16.
currently (day before thanksgiving) Scooter Tuning got 15% off sale MHR listed at $356 CAD ($281 us) normal list $419 CAD ($333 us).
for all the DIO guys, now is the time to get the C16. normal list price $339 CAD ($267 us) but now at $288 CAD ($227 us). that's a steal. hint...hint...to the visitors. $227 for a C16 is outrageous for the type of quality and known performance. it is not direct fit, but it can be done.
for that matter as far as i can see, it's 15% off at scooter tuning right now.

C16 for vert minarelli will fit on a dio? What do you have to cut? I like my Yasuni R that I got for my horizontal, but the metal rusted pretty quickly, cleaned it off and hit it with bbq paint for now.

if not, it's okay. i'm a minarelli guy and this DIO stuff is just for fun.
