• Husqvarna Motorcycles Made In Sweden - About 1988 and older

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

430 AE 84 changing gears problems or carb tuning ?

If you listen carefully on 3rd video, at 6" the motor has some very little difficulties when changing
from 2nd to 3rd at full throttle.
 
I have also tried in dirt, but the problem was the same.
Must not be deaf to hear on video the rev problem and gear changing !
 
Not sure about yours (is it a 3 speed ?) But have you checked the 2 and 3 gear grooves ? Maybe the oil cannot escape the shoe and it is "floating"
Also check the gears on the main shaft. Sometimes they can move slightly and prevent a smooth take up.
Probably none of the above, but trying to be helpful :)
 
i wouldnt worry about that . it pulls through it fine .

maybe it does get a guts full of fuel as you are holding it full throttle so full airflow and suddenly the engine rpm is half what it use to be

Grouty, I have checked the 2nd and 3rd gear grooves when I installed the motor
in the frame. The motor has 3-4 hours of riding since I checked the motor.
I don't think, it is that.
But I hear what you are saying and will see if I can't find solutions with the carb.
Thanks

Thanks for your advice. I'm going to check my main jet to see if it can be better.
 
Hi Michel,

The auto only has 3 gears?

Is the ratio change between 2nd and 3rd wider than the ratio change between 1st and 2nd?

Which would make it sound like it is bogging down shifting into 3rd?

Don't forget 2 stokes make their power that comes on quickly by spinning the tire in the dirt.

Bitumen riding is not going to be a good indicator of performance.

Cheers, Dave.
 
Yes it is a 430 LC 3 gears automatic.
(but a auto bottom end 4 gears + 430 ae top end + electric water pump would be a great idea !) :)
Don't know for the ration1/2 and 2/3.

Cruisetopdown, are you talking in meters or in feet ?​
 
That will be feet Michel, so 150 to 300 metres, I will check the gearing on my 420 over the weekend when I get a chance, Rugby takes priority. Allez les Rostbifs!!
