Where are you from, I'm from Vietnam ❤️❤️❤️

I work as a mechanic at a SYM dealer in South Africa. Let me tell you, if SYM actually made a v twin like this for their bigger scooters like the Jet 14, they would be a big hit! well done this is so cool!

Please build a 500 cc 4 cyl two stroke engine! You will have people standing in line to buy it from all over the world!

[ranajaydeb]

Like the way you subtly reinforced the chasis mounting points....
Great work❤❤

This is truely ultimate DIY, make your own parts and make it work. Simply incredible.

[dennisgauck]

SYM should follow your lead and build that as a touring scooter, they would probably sell a boat load(or more ) of them. Well done, masterful job!

[DK-iisc]

That level of machining and mechanics is incredible. You guys are awesome! Respect!!!

[allankleidon]

What a Fantastic Build, Such Effort and Engineering Skills. A Great Job, Well Done!!!

[Bob-wozv]

Thank your country for this type of freedom.

Another stellar job! Interesting use of rebar for shafting. Much rebar is high manganese because it's often made from "rerolled" scrap railroad rail.
I like your cool self-made tooling and mill clamps too. Your aluminum casting repair skills are outstanding and should be a moneymaker.

Le Dan, you are a seriously skilled engineer. I would love to spend a day in your workshop with you.

Give this man 2 Bugatti Veyron engines, a bunch of rebar, some scrap aluminium bars and a pallet of Aluminium Tig Filler rods and he would make a W32 out of it in no time. Exellent workmanship!

big respect, just a scooter that looks boring, nobody would notice until the homemade converted 250cc engine shows the power, true sleeper

Seine Videos sind ein Genuss, die Arbeiten professionell, hochinteressant, sauber und inspirierend. Respekt!

Lntwin is a name that Ducati invented to make their engines seem different, they are just Vee Twins with marketing speil, your build are still amazing, no matter what you call them.

Genius ! This is so cool. That scooter hauls ass now. Mike from California, USA.

@28:00 It is a good practice to align the pin of the vristpin circlip vertical to the cylinder bore because it can get fatigued
by the reciprocation and break off. I also like to cut the pin shorter to have less mass wanting it to flex. It does not happen often so I am sure you won't be having any problems this time either.
Really nice build, again, big thumbs up! Be interesting to see what you come up with next. :-)

90* L like a Ducati and your bike sounds like one, well done. It’s quick out of the hole too.

[dennisgauck]

Engine sounds great, why one of the manufacturers hasn't made something like this is a mystery. Great job!

[hunterrichey]

If I had something like that It would most likely be my daily driver that thing is always going to be bad ass
