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.
I’ve made a video where i show the steps to make a Vespa moped go faster. It’s a Vespa Si engine from my friend Kim, it came with a Athena 43 mm cylinder kit, but the engine case was not adjusted for this cylinder.
I’ll show you how to enlarge the intake for a 13 mm Dellorto SHA, adjust the transfer and boost ports and adjust the inlet timing on the crankshaft. Watch the video on Youtube here:
Attached is a degreewheel you can print and use, it’s made in 300DPI so the size is correct when you print it. It’s 100 mm outside, cut the inside at 77 mm from center and it fits your Piaggio engine. Click on the image for the full size.
A complete guide to rebuilding a Piaggio moped engine, like you would find in a Vespa Ciao, Bravo, Si, Grillo, Gilera Citta etc. I talk about changing bearings, measuring the ignition components and more.
I’ve been sick of painting parts with rattlecans for a long time. The surface is just too weak, tighten a bolt and the paint chips off. I started to watch some youtube videos about DIY powder coating, i had to try it myself!
I found a cheap solution at nordicpulver.dk – a tribo gun that charges the powder in a teflon nozzle. No seperate charging station and high voltage gun is required. I grabbed a few bags of powder and placed an order. To bake the powder i bought a cheap Ikea oven, nothing fancy and it has a good internal size.
Check the gallery for the result of my first try. I didn’t do anything to the parts to make them look better, i just sandblasted, cleaned and coated them.
