Title: yds5 engine
Post by: petrolderek on November 21, 2018, 04:03:39 PM

I have a Yamaha yds6 with a yds5 engine fitted at some time in a previous life. I have seen on the internet that some ds5s have an electric start. The question is, is the electric start engine completely different because I cant see any way to fit a starter to my kick start engine or did they use the generator as a starter motor similar to the Villiers dynastart.

Starter/generator on right hand side of crankshaft. They were a bit weak and needed a really well charged battery if the compressions were good. I think by increasing the size of the wires would have helped. I mainly used the kick start on mine.

So it is like a dynastart I thought the generator looked a bit heavy duty for just charging the battery. I wasn't thinking of fitting an electric starter I was just curious to know how it was done. Mine starts first prod every time.
