Hi, just finishing rebuilding a YDS3 and can't find the chain size or tyre pressures, anyone know them, also where I can get a copy of the owners

handbook that was supplied as new with them.

The chain is 525 size, 92 links. 525 chain is now considered a quite heavy-duty size, and one can obtain an O-ring type that will last forever on a YDS3. As to a manual, I can only suggest eBay. Alasdair at YDSparts.com might also know of a source. Here's US site that is dedicated to old Yammies: http://www.vintage2strokes.com/index.html

Cheers, as well.
