Hey there guys,

I have been lurking the forums for a while now and finally found a good deal on a Vespa. I have been riding larger bikes for years now but I never really did get over my first scoot. Anyways I got it running but the guy jerry-rigged the whole wiring system converting it from a battery operation to nothing but headlight and motor. I would like to get my blinkers and tail lights back so have decided to put the battery back in. When tracing the wires I started slowly making amends to the harness and cleaning up his mess up when I noticed this bad news coming from the engine. I believe it is coming from the magneto.

My question is how do I get in to replace these wires so I can get rid of the corrosive mess. It is a short waiting to happen. Also I notice when driving it around the block that 3rd gear lurches under power. Like it drops it then picks it up again real quick. Any ideas?

Thanks in advance, David

p.s. this is the only forums I have been able to find for vintage Vespa's in the states. Is there another place or better that I could be asking for help from also?[img][/img]

You will need to remove the flywheel and the stator plate. To replace those wires, you'll need some new ones (obviously) and a soldering iron.
