I wasn’t happy with the printed on transparent foil decals, that i could buy for my Honda PA50. I’ve created my own, a copy from an old original. It’s made in Adobe Illustrator and is in vector format, so a plotter can cut it in foil.
Another spreadsheet i’ve made, to calculate the speed of your moped at a given RPM. You need to know the details of your engine, gearbox, sprockets and rear wheel. You can find most of it in a spare parts catalogue, or simply count the teeth on all sprockets.
I’ve made a spreadsheet that you can use to calculate the ingition timing, to convert mm before top dead center to degrees, and reverse. I think the file is self explanatory, click the link below and try it out.
I made another video, this time i’m assembling a Puch M4 engine. I cover the replacement of the bearings, seals and gaskets. I also show you how to measure and adjust the radial play of the shafts and the order how everything gets assembled.
The information in this video can be used for several Puch shifter engines to some extend, i will also make a video in the future of the most popular 3-4 speed engine.
