Cheers guys, I agree going off the ADB test at the time they were slow and when you consider the opposition and what was coming from them. The A7 was a better bike but by 1981 the others were all watercooled.
The story with the bike was that back when I was on the tools a local called into the servo and saw I had a Thumpernats shirt on circa1996, he said are you into bikes, sure I said. "He said I have an old kx at home and I want $60 for it, I mean I must get $60, it's worth that".
Was I hearing him right? ok I'll call around later. To cut a long story short I picked it up and it was missing the barrel which was left at Campbelltown bike wreckers who had a clean out and tossed it out. I found a barrel and head at Penrith bike wreckers, not sure if it is an A6 or 7 barrel, so most of it is there.
I do have some spare plastics for it but basically needs a reed block, intake and kickstart lever. I found a brand new NOS seat in the plastic bag at Dubbo swap meet many years ago. So most of it is there to complete a resto.
Owes me nothing and it would be nice to restore and show off even if they go like a wet rag.
