Hey, welcome to the forums.
Nice choice of trikes, the 85-87 sx & es are the top of the line trikes by Honda to have for off-roading in the Canadian wilderness.
Many of the
parts on both machines are swappable. So keep that in mind if you are having electrical problems or need a quick fix.
Anywho, many of the
parts you can find on ebay for pretty cheap, just watch out for the import charges and exchange rates.
Like the seat coverings... pre tailored, just save the foam, heat, stretch and staple.
For your ES... using it as a
parts bike might be your better choice. You should be able to find one in a junkyard or anchorage pretty cheap.
I happen to know a place in St-Paul Ablerta that has a few just sitting there in a field that are mostly complete.
Anywho, shoot me a PM if you need more info. Have fun!
