• 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 The previous version was outdated and no longer supported.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!

Thinking of putting a set of race tech emulators in my 73 400 cr. Is there any machining or modifications to the shocks reuired required? Any comments or advice would be appriciated.
 
I have installed Race Tech emulators in both my bikes, 79 390CR with 40mm forks and 77 250CR with 35mm forks.
I think getting the right springs is first place to start. With old sacked out springs you will have to increase your compression setting to control bottoming and your forks will not be as responsive to the smaller bumps. Adding preload will not make a soft spring stronger, as preload only raises the ride height.
Emulators only allow you to adjust the compression rate of your forks. Rebound is adjusted by changing the oil viscosity.
When you install the emulators, Race Tech recomends drilling out the holes in your damping rods to allow oil to flow unrestricted. Intructions are provided with the emulators, but basically they recomend 6 - 5/16" holes. The Race Tech instructions indicate you should call them for a suggested set-up, based on your weight and riding style. But you will ultimately have to spend some time finding the right setting on your own.
In both my bikes I used 15wt Belray. On the 390 with 40mm forks I used the blue (40 in/lb) colored spring and Race Tech recomended preload of 1-1/2 turns on the emulators with the oil level 5" from the top. Damping was to soft and they blow through the travel to quickly. I raised the oil level to 4-1/2" and increased the preload to 4 turns, made a huge improvement.
On my 250 with 35mm forks I tried the same set up as the 390, but it was way to stiff. Ended up with only 1-1/2 turns of preload as a final setting.
I plan to try the 390 with the yellow spring (60 in/lb) and less preload to see if it improves the mid-stroke damping over the choppy stuff, but if I have to go back to the previous setting I wouldn't be unhappy.
Are the worth the time, effort and cost?
If your looking for a bolt-on improvement probably not, just get your springs right and play with oil viscosity.
If your like me constantly changing and trying new things then yes. With the emulator you have the ability to tune your forks to your own personal preference, unlike the fixed damping of a conventional damping rod.
