The Making of Moped Dick - Experimental Test Vehicle 1 

A lot of people can “build” a bike… this man made a bike 🤯

A little thing, but, quick tip for replacing handlebar grips i learned ooooh many moons a go... Hairspray... Clean handlebars well getting rid of grease and such, fully dry, then spray Hairspray (yup the stuffs wimmins use lol) into the grips, slide on, position right, leave to dry, and bingo, well seated, secure grips! 😏👍 😎🇬🇧

I've 3d printed alot of things for my small engines and CF nylon fresh out of the box plus being kept dry has produced the best results. Thanks to you I did a design revision on my reed cage and added a bridge between one side to another to prevent the reed cage from collapsing in from the reeds smacking the cage.

This is one of my all-time favourite bike builds. Hope you get to run it on the salt this time.

Alex I admire your dedication. Weather is a wildcard at B'ville. August is going to be here very soon. Best to you. J.

Bending that metal sure made your beard grow fast

Making reeds out of old credit cards seems appropriate ;-)

Am I the only one thinking of Burt Monroe…..😊

For what it’s worth, wsy way back on the 80’s the cr125rc engines I played with, the reed blocks were aliimium with a rubber coating,. It (supposedly) sealed (it did ! ) it gave the reed petals a cushioned face to seal against. Seemed to give both the steel and the fibre reeds a decent life. We used reed stops and coated them. Think plastic-dip. Ok wasn’t a 30bhp 50cc motor but ithe reeds survived a 4 hour beach race with a 1 mile flat out straight..

Fantastic footage!!! Im glad i have seen the making of the Bonneville speed bike... Cant wait to see it in action 🤘💯

Boyesen rad valve is aluminum. They make a cr85 version

Bonjour, je suis bluffé par le travail accompli pour la réalisation du cadre. Bravo et bon courage pour les essais routiers.

2stokestuffing! When you use the filament dryer to dry. open the "door" about 1 cm. Some driers dont have a vent so moisture will just circle around inside and wont get out. 1cm is enough for the filament to actually dry. Only have it closed all the way when its not running to keep moisture out

The whole factor that was managed to make a blower work with that type of engine design

The '85 250R atc had metal reed peddles...never had issues

perhaps a tapered reed might help? with a single thickness reed the highest stress would be at the fulcrum. a tapered thickness reed would spread the bending stress beyond the fulcrum evenly ....if that makes sense

Sounds like it's gonna be a ripper!

An idea for the reed petals. Wether steel or carbon/glass fiber you could make them from a thicker material then thin them where they need to bend. In that way they would still be able to open as much as needed but be substantial enough to withstand back pressure. Of course they would need to be custom made but it wouldn't be hard. If metal start with as thick a material as would be appropriate then grind away a little from the bend area. If fiber laminate a layer of the thin stuff onto a layer or thicker stuff or two layers of the thinner material like you have leaving only one layer where the petals need to bend.

Have a very good vacation. Love the Channel. One of the highlights of my week. Have a good one!!

I love watch yours timelaps!!!

Always reach out to boysen to see what they have off the shelf

I swear I already seen this before...am i hallucinating? Same frame to be used this upcoming speed run?

Get your stuff 3D printed (Aluminium), really cost efficient. Already order some intakes and i‘m very happy

Just a thing that popped into my head: how hot will the reed locks get? What do you expect the temps to be? Cause if it comes out of a thermal 3d printer, it just can withstand less heat, than was needed for the print. Always funny for me, when ppl print bike and car parts, that melt in direct sunlight 😉

If you think the blowback is because of the compressed fuel/air, then its only one thing to do to solve it. Installing fuel injection into the inlet ports.

A 'floating' [on a spring] pivoting chin brace coming up off the center of your steering assembly could allow you to lower your head with less strain, especially if you can look up high against your eyebrows to see where you care going, allowing you to lay more comfortably at a much lower drag profile. I could draw a sketch for you, if you are intrigued but don't get the idea from just these English words...

Lets talk why the pressure is so high on the reeds. And what way are they breaking. From the crank case or the super charger pressure?

33:36 We still got some Viking genes! Give me a helmet, or i will go without 😁💥🤕👌😄

A lot of 80's bikes have parts still available yamaha rd 125lc 250/350lc, yamaha banshee 350 etc all use the same reed block, same as the tz700/750 metal reeds and aluminium cage, Iit might be worth noting 82 and 83 yz models had a three petal design ,also I have thought for a long time why do the v force etc have no reed guide that curved piece of metal is to stop the reed flapping wildly on the intake wall or too wide and shattering, I beleive the best setting for them was 12mm to the end of the guide from the tip of the reed, I think your problem is two fold 'plastic' and no reed guide it may solve your problem

Snag some anamorphic lenses for gopros and try them out in June and August?

I enjoy the build videos like this.

If you are getting combustion blowback, it could possibly be a good application for a tesla valve.

I would suggest rotary valves to replace the Reed system.

Hi, i love your ingenuity and design process! Instead of reeds would it work with crankshaft venturi ?? This way the crankshaft can pressurise the only downside is the crankcase and liner will have to be heavily ported.

Idea: bond some form of metal piece into the top of the reeds where the flex is causing cracks... ~( 'w')/

Perhaps the reed bridges need to be at 90 deg to the reed fibres?

Köp boysen reeds. Dom har aluminium korg och kolfiber blad.

What motor is going to Bonneville ?

great work, have you tried motul 800 oil, on dyno with my 100cc on minarelli crankcase base i get 1hp more just by switching from A747 castrol to motul 800

Instead of using Reed cages. Maybe try pop up valve. That will only open when pressure is less on back of valve. It's a very old design. But it might not won't work on the rpm's your running.

Fronttire in wrong (Rotation -)Direction?

what if the problem is not the reed itself but simply the fact that the intake ports opens too soon (or exhaust port too late) so simply too much pressure for the reed valve. if the exhaust valve does it's job it can close soon enough and hold the boost pressure a little longer

What if the transfers had a sleeve valve to seal the cylinder? 😺

That seems so long ago..oh yeah it was..😁👍🗽🇺🇸

METHADONE MAN from Montreal : PLEASE CHECK OUT JAPANESE 50CC ,75CC , AND 125 BIKES FROM 1969 ,70-71 . GO TAKE A VACATION . YOU LOOK HAPPY !

I hope you're not rushing into it. Why not build and proove that the engine concept really works before sending it accross the world? Personally I would not go there with just one setup. Hoping for the best still.

If you're having issues with read valves and rotary valves. Why can't you put a conventional 4stroke head on your engine with custom cams to run "2stroke".

A lot of people are moving over to the Osmo Action 4 camera which I have its worth a look Not buying GoPro again

Could they change to Black Rock? I guess that would be a giant SNAFU.

20 minute pikes peak on a 50cc when??? 🤣

You need to start anodizing your raw billet aluminum pieces so harmful fuel’s don’t corrode your internal precious part’s. It would last a lot longer. Try cryogenically treating the crankshaft and connecting rod also for hi revving ,flexing and or breakage.

Oops, heating that brake cable red hot lost all of it's cold-worked strength, please re-do before riding.

Your work is university level maybe even more. Kids in universities are just learned to walk so how they can innovate something new.

My ktm ate a V force reed cage and some petals, it caused some major damage to my engine. That plastic is junk, the fiber chop is strong enough to do damage but not strong enough to hold together. I'm trying to process a warranty claim but they claim my engine destroyed their cage when it was the other way around, their cage went through my engine...about $800 later my ktm is back.... friends don't let friends use moto tassanari , plastic reeds....love my boysens on a metal cage coated in rubber

What's up with the name of the vehicle?

❤

Getting that cable red hot 😮 is not a good idea 😢

would it be worth moving the reeds from the cylinder and to the crank case, so there not directly facing the wave sites?

🤯

👍😎

❤👍😁

Wd-40 is a joke.. you need boelube..made by boeing airplane company.. it is the best on aluminum

out of focus pleas chance kamera

Mission control we need a motor before take off

tooo much pressure and backfire No reeds... Make an Injection!!!

Maybe you should try experimenting with the Nicola Tesla valve?

Ahhh the sweet sound of a very fast 50cc 2 stroke sounds like music to my ears ❤

This is exactly the moment than i have discovered your channel. And a bit more latter i have send you the titanium screws.

30hp 50cc engine... What a beast

Hey Alex, one thing to keep in mind, the salt will destroy everything, it may be worth it To enclose all the electrical parts.

Looking forward to this year with your runs!

I hope you enjoyed Pike's Peak, that part of Colorado has some serious beauty!

They really need to sort the flooding out on the plains 😂😂

That sound when it pulls away... Good job you are a good mechanic

You could have cages 3d printed in metal for an affordable price.

Glad to see a chain guard right away on new bike

This is really a momentous occasion; an engine that is running on an actual machine! I think this is 1 out of 200 videos; outstanding; i have been waiting to see one of your engines in motion.

I know I enjoy 50cc 2 stroke stuffing... How about 0.25 mm thick titanium alloy for reeds...impervious to gasoline nitro or methanol...? I am sure some travel limit can be installed.....to limit either material... Sure, then a new toy..or simulator could be ran 24x7...to see their fatigue strength ...then change out....just prior to the record.. I hope you and family get to Spain...or Gmbh...for holiday...someplace where your currency is strong...maybe now with the Euro...it doesn't help? I loved my trips to Europe... I almost got to Phillips...back in the day...but your engineers were wise enough and didn't need my help or hindrance.. Alex...my neighbors complained about my piles...so I took a car and truck to get service...in an effort to make yard pretty... Boom money bomb shells went off. I will still help you...because I have honor said I would and love speed.. I will help a tiny... Either patrione...or when you get to states and your support..tell me your buddy phone Anyway I am sure I can find a method...plus you already shown instructions ... Boom Zelle.. $200 ... I intend to watch in person.... My 69 IHC Travelall is almost ready for a Bonneville run herself...but not quite ready.....more time is needed... I have too many other money sponge projects... Aero dynamic the IHC is not. A farm implement it may be, but is quite road worthy... Come on lottery... I always wanted to follow foot steps of my father....born 1910. In early 30's he and his buddy Glen Jackson...did their best on grandma's old 1925 Ford model T... They drove it from El Monte CA to Utah... Race prep prior -an oil pump installed, cut off top and milled head. Some better exhaust. Two carbs. No speed records were broken.. Pops topped out at 106 mph in a Model T... It is in my blood.. May you Alex- break all the rules we bend...

Enjoy your holiday brother.

Would be interesting to see your new reed box put on an 80cc stock engine with that kind of boost. The unit would be quite the powerhouse!

Our race team uses AIM DA systems. What things do you want to observe?

Yes❤

I was going to say that you need to housing out of steel, but I found you are on the track. We made are reed house out of steel, and in 1966 the reeds were made out aircraft titanium .010 thick.

Are the reed valves breaking because there is so much more combustion pressure compared to a normal 2 stroke? If so, then its really impressive

If you are having trouble with carbon fibre nylon, have a look at PET carbon. Doesn't warp, strong, high temp resistance, up to 180 deg C after annealing. PET not PETG. Prints beautifully. Need to run 0.6 nozzles though.

There are different PC based materials that could be more suitable, they dont creep as nylon do. Give swedish AddNorth a call, they might help with some sponsored rolls.

Alex, you keep suffering with this none sense valves. Reed valves not meant for engines with blowers, disk valve not made for exhaust. You should switch over to poppet valves like the rest of the world. Use 4 valves, desmo if you like, reduce the speed to half, 2 exhaust valve open at a time, next time the other two. As for the transfers, you don't need them! you have positive pressure from the blower.

My biggest issue with EPACF has always been bed adhesion, I dry for 20 hours at 70 degrees C (highest my dehydrator can go) and have tried Magigoo, and Geetech JT17 on steel, PEI, Buildtack, and Glass, but never seem to get 100% adhesion, so EPACF reed blocks for me would be a non starter, I’d go straight to Polycarbonate.

Oí, sua moto pode ter carenagem? Hi, can your bike use fairing? IF YES , The speed will grows up a lot! with advanced aerodynamic fairing .

I would think a reed valve would produce a lot of restriction, especially at higher rpm/flow rates. Is it really needed with a rotary valve? Maybe the super charging will over come the extra drag without any issues but everything counts when you start going fast.

if the reeds dont hold up in testing, we wont need a cage or wheels !!! IS THE REED VALVE ISSUE FIXED, DEPENDABLE ??? it was a great video, keep going man.

U must speak to Tony Doukas that specializes in forced induction Reed valves. He will sort out your Reed problems.

Now that was a blast from the past 😎

Maybe you can put a "safety mesh" that will catch broken parts before they enter the cylinder. just a thought.

Is there nothing to catch broken reeds if they get broken? Something like a catch basket made of stainless steel mesh?

you can use rubbing alcohol on the grips to put them on more easily

The ecta is running soon, might check the possibility.

ditch the reeds... there are other, far better options....

now I want to see someone ride it at least 1,000 miles in the US.

Hope you get a record at Bonneville this year!
