500 power wars..
Husky always had the smaller engines for their open class, initially the 390 which then became the 430 after pressure from customers watching the japs go 400 - 465 and 500.
Husky responded with the "beast", the 82.5 500 which was a monster. 40 - 50 HP straight off idle, 160Km's flat out straight out of the crate. After receiving different feedback than expected, lots of work went on 83 84 taming the big beast and trying to make it usable.
Unless your 6'4, built like a brick sh*t house and love an epileptic motorbike underneath you, go the 430. You can crack the throttle hard and maintain some vestige of control!
The bikes are dead simple and as a kawasaki dealer said to me years ago when i had the wr 240 in the back of the ute. "f#ck, only a handful of nuts and bolt hold the damn thing together!"
Bearings are std SKF sizes and can be bought anywhere. lots of factory info on Cafe husky website and lots of husky nuts that can help.
Mick at Bendigo Dirt Bikes has husky stuff coming out his ears so a great source of info and bits.
Want a big Husky, get an early xc 510 4 banger, they were unreal.....
