was off today so dialled in the timing on the little G, finished off all the wiring (all works) awaiting the chain then I can tighten up the mag properly.
Still need to find a Dellorto filter (steel one) 32mm female thread.
something like this;
found the tank was like sand inside I soaked the inside with vinegar and I think this is the rust particulates.
I have some acid stuff from the FZ tank, so i'll have a go with that and fill up with pre mix, to stop the rust reforming.
