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 The previous version was outdated and no longer supported.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

1976 WR360 gurtner 38/mikuni 36 swap

I was trying to put this post in Vintage Tech Ref and Parts but couldn't figure it out. maybe someone can help me on that :)
more to the point... I'm changing the 38mm Gurtner stock carb on my 1976 WR360 CC to a 36MM Mikuni. I need to find the optimal jetting and settings for the Mikuni at (sea level). Any help would be GREATLY appreciated. Thanks! Brrraaaappp!
 
A friend of mine has done the swop with a 38mm. We started with standard 390 jetting. Way too rich when started so came down on a few bits. I need to speak to Rich in the next day or two, so I'll ask him what the exact specs were. I starts and runs beautifully.
 
thanks grouty for the reply! I got a Mikuni on order from Sudco to include (for an extra charge) the (according to them) correct setup for a '76 WR360. I'll post what they sent me and we should compare your research to what Sudco came up with.
thanks once again!
 
The only downside is that you say you are replacing the 38mm Gurtner with a 36mm Mikuni ....
 
Let me know how that swap goes as I am in the process of optimizing a 76 WR360 and have heard about that switch. On another note; your tank color, is it original, I am looking for the correct color for that year, model?

Thanks for any help!
 
I believe Husqvarna used 38mm on everything 250 and up when they transitioned to Mikuni until the 500 came out
 
I was told by John Le Fevre @ vintage husky that the popular swap was from 38mm G to 36mm M. I'm not interested in "top performance" because at 53 years old (me), the 360 has more than I can use anyway you look at it. (just bein' realistic!) I hope he was right though... thanks for the heads up!

I'll post everything as it comes in and will gladly answer any questions you have along the way. I've restored japanese bikes before but this is my first at owning/restoring Huskys! Every step will be a learning experience so i'll probably stumble from time to time but I'm really looking forward to the taking the ride.
I'll keep you posted on carb/tuning and discuss results but as a disclaimer, I WILL NOT be tuning for max performance but more for ridability.
The color is correct for the 360 but MY photo doesn't accurately show it. My research (so far) says the color was a one-off one-time used on the 360 in 1976. Thankfully my tank is original and in perfect condition so all i have done is replace the petcock and under tank cross hose. This link will show the color more accurately,

I will stay as true as possible to getting original husky parts for the 360 but because I plan to actually ride it, I will probably (decompression head!!) stray from the plan. My '74 CR250 Mag on the other hand will be exacting when I finish.
ride-on brother...
 
Thanks for the input. Here is a photo of my WR390 when I bought it, with wrong tank and wrong pipe, I think the pipe is from a 1975 CR model.
I'm hoping to make it into a slightly modified rider as well, thinking of the carb swap as well to help in starting.

WOW! that is CLEAN!
 
Here are the specs as delivered to me pre-installed from Sudco for a Mikuni VM36S special order specifically for the 1976 Husqvarna 360 WR @ sea level.
60H2 Jet Needle/320 Main Jet/159 Q8 Needle Jet/50 Pilot/3.0 Throttle Valve.
Retail for the 36mm Mikuni stock is $114.00
W/pre-installed parts, $202.28 (they won't even give you the old parts that you ALREADY paid for! Jeez
This is a spigot mount carb and Sudco advised "radiator hose" as the accepted method of adapting. Just so happens, a hose from my local auto parts store not only fit (custom sliced of course) but I managed to find the proper "step down" in hose diameter pre formed on the hose (at the end of the hose that meets the car radiator flange the diameter is slightly larger than the rest of the hose. How handy indeed!
 
Thanks, I will be looking into that. Let me know if you notice better starting and running when you get it back together.
 
I bought that bike for 1,800 at Mid-Ohio a few weeks ago. Defiantly some rattle can restoration going on, but almost complete and runs, so its a good start.

Do you have the part number for that hose? Little tidbits like that are really helpful. You'll save "the next guy" from standing there wading through 400 hanging hoses at the auto parts store!
 
OH Ya!! There are a lot of guys posting things like "I used the Yamaha carb needle and it fixed my jetting." Nice. But useless for the rest of us. What are we supposed to do with that? So thanks a million!

REMINDER: this is for a 36mm Mikuni round slide NOT a 38mm!...to replace a 38mm Gurtner
Obviously, choose quality hose clamps as close to the actual size of the hose as possible. NO SLOP! I found some that have large black wingnut type fittings rather than the screwdriver type. I'm painting them black so they look like they "belong" on the bike...

I know this is an old thread, but exactly what I'm looking for! Thanks and anyone who has done this for 7000ft and figured out the jetting, please post ! Pat
