husky 430cr

Sorry I should of noted air cooled 390 / 420 / 430 use the double reed box setup.

The liquid cooled bikes use the newer rectangle reed box.

I guess husqvarna pushed out what bikes they could with the parts supply they had in the early to mid 80's.
The transision to liquid engines had to be tough. Even the change to the single shock.

I still find the twin olin gas shocks the best suspension there ever was even today. There's a frame to swing arm flex I feel on the single shock bikes of today. I feel the rear tire is steering trying to pick another line when leaning. I wonder if the dirt bike designers will see and understand what this flex is doing? Someday thell wake up and say oh look what we discovered "twin shocks"???? DA??

I could go as fast as I wanted too with the twin shocks. The swing arm never bounced. The old front forks wether 38mm or 40mm worked fine. Now today there is so much adjustment in everything we need the engineer who designed it to make it right. My guru bike buddy says the dealer who sells the bike should setup the suspension. At least close for the purchaser. Every new rider thinks you just get on and ride. I get the adjust what? They don't have a clue what's race sag? What's rebound? Then it's the bikes fault when they have problems riding it. Each individual riders weight and style is different. Why are the suspension settings so fine tuned on the newer single shock bikes?
Give it just three settings? Light, medium, hard. Then change rear springs and fork oil weights to set it to the riders weight. Keep it simple? Why so high tech?

the later 430 ac used the box style as well

The 390/420 has a 71mm stroke while the 430 has a 74mm stroke. That's only a 3mm difference. I believe the 420 gets close to the 430 in the bore size?

I've never seen an air cooled 430 with the box reed cage, do you know what year had the box reed? The '83 was the last air cooled 430 as far as I know and it had the old reed cage.

The 420 is the same bore size as the 430 with 3mm less stroke.

Bill,

There is a big difference from the now modern machines versus the old vintage machines.
We are running faster, hitting stuff harder, and flying longer in the air/further. This is stuff I wouldn't even dream of hitting on a vintage bike at those speeds. Who would of thought that instead of ordering needles and jets, plus a lot of guessing versus hooking up your laptop and changing your air/fuel mixture in 5 minutes? Soon you will see the exact same stuff on a modern two stroke.

if there is anything i dislike about a certain vehicles suspension its that you cant externally adjust it. i try to get my suspension dialed in as best as possible, and im constantly learning better ways to do it. if someone is confused by having rebound and compression clickers, its not the manufacturers fault
