Several more modern replacement parts for the KXD-2 just to hand.

Filter cartridges to fit the original Bendix Type K filter canister: *AIR FILTER WISCONSIN SUBARU ROBIN EY 1573620101
* NOTE: Leave off the foam pre-filter that comes with this cartridge.

Electrical ignition parts:
Original ignition ground plate: LMPT6Z
Bosch points equivalent: Bosch 1-217-013-021
Original condensor no: LMKO1Z1Z
*Bosch condensor equivalent: 1-237-330-035

* NOTE: Someone else told me that the correct Bosch condensor is 1-237-330-037
I am not sure if there is much difference between the 035 and 037 condensors in any case???

Fuel caps: A suitable replacement is O.E.M. No. 157/40. VINTAGE GAS TANK CHROME CAP 65mm FUEL FILLER HUSQVARNA MAICO ZUNDAPP Penton KTM
for example http://www.ebay.com.au/itm/351872397022
WARNING: This is a very expensive cap, but it will provide a perfect fit and last forever!

Thanks to PaulC, a far cheaper option which also fits the Southern Cross KXD-2 is Tridon Non-Locking Fuel Cap - TFNL206V available from Supercheap Auto and probably also eBay. This is a neat chrome cap. It has a wider outside profile than the original cap and ventilates from the bottom.

Plastic wheel caps The originals are a very difficult item to find in any condition. Believe it or not, I have found these furniture end plugs which are basically the same shape and can be adapted to fit. The 40mm size is the right one. Just cut back the insert so that it looks like the original, then maybe add a spot of glue for good measure. cool http://www.ebay.com.au/itm/311838640302
