Hi, just discovered this forum after picking up a DT360A project bike. Also have a TY250A, IT250H, 3 x TT500C’s 
I had a DT250A new when I was 14, but sold it after getting a near new TT500. Anyway saw the 360 for sale at a reasonable price and nostalgia kicked in. As mentioned by another Aussie in the intro’s, parts here have dried up, there’s still a few basket cases on marketplace, but they’re always a 1,000 klm’s away. These bike were once plentiful and cheap in Aus’ but most got ridden into the ground, or rusted away in a paddock. Plenty of stuff on US eBay at high prices with ridiculous postage costs. Considering our dollar buys 65US cents it’s not really viable.

Anyway my 360 is in a 250 frame, built up from bits and pieces put together with random nuts and bolts so my plan is to turn it into a period enduro bike that I can ride without doing anything irreversible to it. In the meantime will slowly hunt for missing pieces.

As you say, USPS are taking the pi** with their charges.

Some parts do turn up in the UK, especially if they were also used on different models - CMSNL and Partzilla are good research sites for this. CMSNL even have some NOS parts. 

I’m not so sure it’s just USPS, Royal mail used to be cheap as chips. I’d get my Rotax parts from the UK rather than the , especially the eBay one.
