yeah i read that as well ! Besides who knows, these days how many are original! The smaller forks still worked well, especially in the shorter travel, they did flex a bit in certain terrain but they did work well in the bush, the later bigger size helpped the steering a fair bit, i tried a set on a 390 with no other changes and the difference was a lot, but it was at Dargle (mx track Nth West Sydney). We have a 390 auto with the small ones, shorter travel and even now it is good, stock as a rock, even original fork seals AND TYRES still ok, you'd never have thought tubes would last this long but they still hold air! If only it had a manual box! The 81 430 was a BIG step up chassis wise, '82 was pretty much same bike, a few updates only. Both are a nice bike, really nice bike, come to think of it i should have one, where is this one for sale.....
