Knew it was year of the Ciao

todd amundson /

So I finished. It's 2021 in a couple of hours. I posted something about 2020 being the year of the Ciao and I'm just making it. Some friends brought this Ciao to me four and a half years ago, maybe more. Apparently it came from a junkyard near a desert. It must of had a car parked on it.

The forks were folded, bars pretzeled, wheels squared rather than round. But it was complete. I started building this a year ago. Plan was to use as much of the original stuff as possible, hubs frame, seat, controls, electrics to keep the cost down. This is Vespa. If you wanna go quick it’s generally gonna cost a small fortune. At least I found it to do so.

I first had to straighten the frame and weld in a support plate. The right side of the frame was creased. These frames are kinda flimsy. De rusted the tank and Caswelled that sucker. The frame was cleared once I finished all the metal work. I only waxed the front fender as it wasn't straight the day I was painting. I knew I was going to add a crossbar but wanted it to be removable. I used a piece of aluminum tubing just like on my Cornflakes Derbi. It helps. The bikes stiff. On the road it’s a little too responsive. I’m slowly moving the bars back every other ride at full speed to see if it helps with jerkiness. I got the bars from Mike Bully for like ten bucks. BMX style. The knurled stay locations were wide so I had to find a 21.1mm quill stem in wide spread to rock them. While there are stems for BMX and shit that are like that, the cost of them is outrages. Even a $200 crusty one. I cut up the top yoke plate off a Maxi and made one.

I did have to purchase a quill extender to weld the Maxi plate to. Works as it should. The real jazzy jazz is how perfect the headlight bolts/fits to the Puch speedometer location. I did have to extend the ends of the bars a lot and make a new throttle tube basically to use those pro-grips. And you all know how shitty the stock Domino slide throttle is. I brazed a washer to the tube and am using a return spring made for late model tubes?

Not sure but there’s zero resistance on return now. Tried to stick with the original grey cables. Jezus, that harness was crunchy. But I did use all of it. And hell yes that horn works. I have a 12v lighting coil for Kinetic on the points case. Not sure of its output but it works fine. GY6 regulator in the headlight housing. I did convert the horn to 12 volt Kinetic installing it into the Ciao housing.

I moved the seat back maybe three inches. Its got that cool swinging post thing going on but it’s still a rigid so need to take it easy on crazy speed bumps. I did however try to make the best out of the EBR front end. It’s essentially a clone of the original swinger assembly. You just swap guts from your original fucked up forks. Even with the new EBR forks the front wheel has a list to one side still. The cast axle carriers have been opened to except a 12mm axle for sealed bearings. I made the damper mounts. The kit from Mo-parts is like $100 bucks and this cost me around $18. It’s incredible how well it works.

Wheels are Pro-Wheel 3’s, 17x1.40 aluminum hoops. First saw these on a certain raced out polini E50 from Sacremento. Those were gold. You can get them in just about any color. The spoke holes are big boy so I had to use spoke washers. The 36 original rear spokes I could use, but I had to cut and thread the 28 stainless spokes by hand for the front. These wheels are super light and you can buy them around $60 a piece. Tires are 2.00x17 VEE RUBBER.

The motor is more of an experiment. Seporn gave me one of those first generation bicycle reed blocks to mess with. I made a plate that it mounted to and welded it to the big case half. The charge shoots on top of the left side crank lobe.

Reeds are from a Dio. No stops, stainless helper fingers. Im using a Kinetic CDI/no curve, full circle 12 pin Malossi crank, Malossi Deps kit, Malossi Multi vare with belt. The case match required lots of epoxy. It’s the stock points case. Once the flywheel was installed it wouldn't spin because it hit the transfer buildup. That motor’s glued together. It’s good. The 21 Oko is drinking a 125 main. Oh, the carburetor only had use of just over half a tank via gravity. The Mikuni fuel pump actuates off of case vacuum. It’ll drain the tank if the bikes running.

The exhaust is the one that comes with the Simonini vespa motors when you buy the whole kit. I’m not impressed. I used the largest outlet flange that came with the DEPS kit and modified the exhaust header to fit.

No way your’e using pedals with this mounted to a Ciao. Needed a right side extender.

The right side of the kickstand needed to be cut off and made into an erector set for pipe clearance. The stock clutch was modded to fit two GY6 clutch arms. It’s real important to install the stock shoe bumpers when moving the scooter type clutch arms. There’s an administrator that'll tell you differently. Fuck that, it only involves moving a few posts.

Here's the two shoe with flat reed springs.

Because the shoes are flipped in this orientation the trailing edge of the shoe is opposite than your direction on a stock clutch or starter shoes. This allows for much weaker springs than you would think. I started with heavy duty and now I’m down to the weakest I could find. The current springs are stock Vespa Grande. Probably the nicest clutch Iv’e ever had. Fucking rips dick and stall is perfect. And it’s a two shoe. I’m currently working on a starter solution that doesn’t involve rope, one way bearings, electricity, kicking or starter shoes. I am using starter shoes now for starting. Pulleys are 100mm, yellow contra, front multi-var, 32 grams total. Belt slap is minimal if at all. Mosquito Fleet sticker for awesomeness. The speedo is currently working and counting miles. When I first received the bike it was working so it’s about to hit a true 1000. Shot way to close on an IPHONE 5. Happy 2020. My year of the Ciao.

This is a cool build. Always great to see someone risking it with one-off, potential fail mods and working out the kinks the hard way.

Kudos

Re: Knew it was year of the Ciao

Awesome build. So much cool out of the box stuff going on.

Re: Knew it was year of the Ciao

Wowow wee wow!

Best build of 2020, this is awesome! I love the reed case. Everything about this is so trick and creative, executed beautifully!

Re: Knew it was year of the Ciao

You got to that top reed mount before I did.

I drew it in a year ago and it’s been sitting ever since. Great idea and great job

Now you get to destroy your ass!

Re: Knew it was year of the Ciao

Wow this is awesome. Great job! Definitely my favorite bike of 2020!

What type of epoxy? Jb weld?

How did you ever fix the problem of the flywheel hitting the transfer epoxy build up?

Badass build!!! What kind of speeds are you seeing?!

Re: Knew it was year of the Ciao

Jason ( ͡° ͜ʖ ͡°) /

Do you think you could also touch on how you incorporated the mikuni pressure actuated fuel pump? It looks like you used the oil feed on the intake for the pressure hookup?

Were you finding that the bike was starving otherwise?

Kinda just going to post pictures out of order on this as I find them on my phone. I have under 100 miles on this motor. Temps are in the mid 300’s. Had a new orange trail tech temp gauge not work out of the package, ugh. Pipe needs twelve more inches of stinger. I have traveled 47 mph and 51 mph on the same road. Hitting anything above 50 requires gears! Where are you all hiding the gears motherfuckers? Higher speeds are hit with lower roller weights at the moment which is weird. Anyone want to share their weight on their multivare Vespa? I’m in the 32-38 gram area with six rollers.

Most of the case has ET22 anchor epoxy on it. There is a skim of JB weld on the outer surfaces. The ET22 by Simpson is like glass when hard and it falls into porous castings easier. It’s real runny and you can easily pour more on top for layers.

The flywheel hits the case! Removed the fan from the flywheel and removed 2mm off the steel skirt of the flywheel with a surface grinder.

Re: Knew it was year of the Ciao

Just curious for information purposes, Is it the Kinetic Flywheel with the plastic fan? I had one hit the cases too, with no modifications to the cases. I put the all aluminum one on and it cleared everything with no problems.

Re: Knew it was year of the Ciao

todd amundson /

Yeah it’s Kinetic. White plastic fan, steel flywheel. It’s the taper. Cut to shallow

👌🏻 Thanks

Re: Knew it was year of the Ciao

This is a cool build. Thanks for posting it.

Re: Knew it was year of the Ciao

Why didn’t you just cut the flywheel?

Am

I missing something?

Re: Knew it was year of the Ciao

I thought Todd said he did? I just used the all metal one that did not rub.

Re: Knew it was year of the Ciao

todd amundson /

I ground it instead of cut it on the lathe that I don’t have. The work is getting all of that shit off the magnets

Re: Knew it was year of the Ciao

There’s no factory nipple on the Chinese aluminum manifold, I added the brass one. It’s line goes directly to the face of the pump. This 1.5”x3.0” pump is for lower volume applications, think Colmer style kart motors. It has the vacuum nipple on the face, fuel in and fuel out on the sides. It’s good because of its size. The other diaphragm pumps are like hockey pucks.

Re: Knew it was year of the Ciao

I just had to replace this one on my John Deere lawn mower, it would probably be really good for mopeds, cheap and small.

Re: Knew it was year of the Ciao

150psi compressed air will blast metal scraps off flywheels pretty easily. Or run a rag around the internal area and then just grab the pile of metal shavings

I thought Vespa flywheels were aluminum tho

Vespa flywheels are aluminum.

Kinetic CDI has a steel flywheel with a plastic fan blade screwed to it.

Re: Knew it was year of the Ciao

Nice work!

good to see ciao getting some love and attention

Definitely change your gears if you’re looking to cruise past 50 and into 60?

Fast ciaos are scary

Re: Knew it was year of the Ciao

My Kinetic flywheel is aluminum, same as the Vespa one but with a filled-in window for the points
