Allans Lowrider Puch Maxi K

My friend Allan had a dream to build a low and simple Puch maxi for shorter rides. We found a Manet Korado that had a good engine and some nice 16″ rims. We kept the parts we could use and sold the rest again.

Another Small Pistons member had a rigid kickstart frame for this project, all the other parts where bought new at JMPB.

We kept the design very simple, everything that isn’t necessary for riding is removed. Allan wanted a low Maxi in black and white design. Check the gallery how that turned out, remember to read the image comments:

Vespa Malossi Clutch

Just a quick warning, don’t buy the Malossi clutch for the Piaggio/Vespa engine. All the materials are very soft, there was nearly nothing left after only a few rides. Look at these pictures:

 

I used softer blue polini springs, which reduce the wear even more than the stiff black springs that it’s shipped with. Luckily i was close to home and not on a long touring ride.

The last pictures are of my new Newfren clutch that i lightened, works great so far.

Moped USB charging

When i’m riding long trips with my phone for navigation, i drain the battery pretty fast. On my Kreidler i have a 12V 80W system, more than enough power to charge my phone. But most of my other mopeds can only provide 6V and 17-18W. I’ve found a solution to charge a USB device that is ready to buy and mount. It’s a german made bicycle dynamo adapter, the model number is M172N and it’s made by a company called Kemo.

It’s rated at 0,8A charging current and it’s able to take an input voltage of 6-70VAC.

I have it mounted on my Vespa Bravo at the moment and it works great. You obviously need to turn the lights of to charge. The stock ignition only makes 18W and i have a 15W and 4W bulb connected.

Yamaha RD50M – Engine

I pulled the RD engine this weekend and disassembled everything. Of course it will get new bearings and seals, the crankshaft is still very good, as are the gearbox and clutch. But the clutch has to go, it’s a two plate model, i will try and fit a four plate clutch from a DT80.

There will be some machine work done to the crankcase, as i will fit a cylinder from a Minarelli scooter engine. The gasket surface needs to be lowered 2-3 mm, the bore for the cylinder skirts will be enlarged and the transfer ports need to be matched.

Yamaha RD50M 1979

A new project again. I’ve had this Yamaha RD50M for a while, and no plan for it. It’s a german 5 speed model, it can never be ridden as a Moped in Denmark. What better to do than a tuning project?

Right now i’m stripping it for parts that i don’t need, less weight and fewer parts that can fall off đŸ˜‰

The engine will get new bearings, seals and some porting for a larger cylinder kit. At the moment it has a 45 mm Polini kit with a 20 mm Mikuni. A good daily driver with a topspeed of 80 km/h, nothing you can win a race with. I need something faster, more about that later.

The gallery will be updated with more pictures in the future.
