The ktm box is actually smaller than the motorized bicycle cdi box you can see the exhaust old ktm box still on the subframe. I do have a timing light I need to check that next.

I’m using a 8$ cdi box from a motorized bicycle engine. I’ve read that they get erratic timing at higher rpms. I have yet to experience this but I haven’t ridden the bike much due to not having the proper size jet.

This is the cdi I’m using

The belt is long enough it’s the wallaroo / fox belt so it’s wider than stock Vespa belt. I still need to make a spacer for the variator so the belt will sit on the variator shaft which will bring the belt to the top of the rear clutch cheeks.

I’m going to try running the lights with led bulbs off of a drill battery, if it doesn’t last long enough I’ll get a larger battery.

Almost finished with this moped, still needs some carburetor tuning, and lights wired.

I got the bike to run. Here is a video of the first start. I’m getting a lot of belt slap, but the bike is fast for the short ride I took.

• I have a very weak spark from the ktm cdi setup. I’m waiting for another cdi box hopefully that solves the issue. Here is how the bike currently sits. I also painted my rear snowflake mag for the kinetic.

Here is the weight difference between the steel and cast version.

I have 2 stroke wizard from buildandclick.com but for this pipe I used the specs from the Peugeot Doppler pipe. I found the dimensions on the mopedarmy.com website.

i like the idea of using aluminum behind the weld I’ll have to try that next time.

I’ve seen the rotor used on a few builds before. It seemed to me that all the ones that cracked the builder had mounted a fan to it. I’m using a water cooled head so I won’t need a fan. But If there is a problem I can machine a steel sleeve to slide the rotor over.

Here are some photos of the pipe I’ve been building for the bike.

Yeah, I cut the taper on my lathe for it to fit the crankshaft.

Here are a few photos of my current project. Vespa grande frame, forks, disk front brake, scooter clutch with the shoes flipped and a brace added, sub frame stretched for the wallaroo belt, 46mm polini cylinder, speed style case, 15mm sha carburetor, ktm 50 ignition.

Thanks, receiving the moped of the month is awesome. Especially for the kinetic, it’s typically a bike people don’t like here in the states. Most of the time people buy them to swap the motor in a Vespa since it came with cdi ignition setup and 12 volt lights.
