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 The previous version was outdated and no longer supported.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

How about performance reeds?

How about upgrading to a better performance reeds?

Now we have two different types of reeds. The 70's era with the detachable reed box which continued into the 80's on the AC 430's. The 80's 250/500cc had the reed box casted into the cylinder. Is there any upgrades besides installing boyzeen reeds? What's the best performance reeds we can use? For both applications?
 
Really only two. Mossbarger and V force. Huskydogg had right to sell to north america but left vintage bikes last year. Andy has
the V force now.

I installing Mossbarger on my 430s and now have a set for the 500 build. Just really pleased on the 430s. Want to try a V force
on the 430 to compare. The 500 is the reeds and new mounting block. 430 is a complete whole unit.

Will be putting a V force on the 250 build , have to order those soon.

Here is something I can not answer seems the Boyeson I have used i just don't know when they were made. All seem to old stock and what condition are they in being so aged ??
 
I have a mossbarger reed block setup for the earlier reeds. Now I just looked at Andys v force setup for the 430cr that you mentioned. I wonder which reed setup flows more?
 
"I wonder which reed setup flows more?"

probably not much different, its in the petal thickness as to how they open which affects flow at different rpms. the two stage boysens give a kick in the low to mid as the small petals open quickly before the larger backing reeds open at mid to top end as per the stockers.
 
i would bet the vforce setup out flows stock and the mossbarger. its quite a bit different than the stock cage, not just replacement petals.
 
Unless you are building an engine just for dyno pulls or road racing, increasing flow is irrelevant as even the stock setup flows more than enough. What you need from a reed is more precise control of the flow and better response time to the pulses. I have heard pretty negative stories about the the quality control on V Force reeds, the molded part is not flat and even with a paper gasket and sealant they have air leaks. Before Huskydoggg quit he gave me a V Force reed to try on my 430 but I have not installed it yet.
 
In the old Husqvarna late 70's reed block, the v force has double the reed pedals. Instead of four it has eight. Since there's no adjustment on the v force reeds if there's a gap in the pedals how do we close it up since we can't flip them? Maybe the mossbarger with the boysen reeds? I noticed that mossbarger doesn't offer the older husky reed replacements. They offer the four bolt reed replacements.

So after hashing this around what's your hot setup?
 
If the V Force reeds are worn you replace the petals, which is what you should do on any reed, but what I was talking about is the gasket surface where the reed block mates to the cylinder.
 
The v force reeds do not seem to be removable, there's no screws. Can the gasket surface be filed flat to properly fit?

The boysen reeds are a two stage reed. Is there an advantage to this. There's no movement limiter on the boysen reeds. I notice on some v force reeds the opening is limited. Are the reed petals made from a softer material so they open quicker on the v force reeds?
 
The reed petals are held in place by the outside collar, the inside case has raised posts that the petals sit on. Yes, the gasket surface must be sanded to make sure the surface is flat.
 
Is the correct Boyesen part no.612 for 81-82 430CR's? And you need 2,right?
Never seen a more confusing way to list what fits what.
 
Right,and you need 4 reed petals to make a set for 1 engine.
So you would need to get (2)part no.612's,I think(grin)
Thanks
 
Bill what ?? No. The Mossbarger has designed their own reeds. You engine bike building knowledge is amazing Bill

Please build a bike now or today and then come back to us with answers based on experience and true feedback.

Almost everything is just plane pulled out of somewhere.
 
ok ok ok all lighten up here

and Bill. please many knowledgeable builders here who have been there and done that and still doing it. they do speak of what they know. so if you don't agree, please then just disregard them and build your bike the way you want to. it is that simple.

Respectfully
Joe
 
I'm miss understood here sorry. I'm looking for you guys input too. I checked mossbarger for new reeds for there late 70's /430 reed block they don't offer replacement reeds. The only choices I have is the boyzeen dual stage reeds or v force.
I'll let you guys choose for me?

I'm looking for what the best performing reed setup there is?

Please no flame intended. I'll go away now.
 
My pick would be, unless your stock reeds are broken or otherwise damaged, leave it all stock. For many many years I assumed that anything aftermarket was automatically better than stock, no matter what brand the bike was or what kind of part it was. Through lots of trial and error and more error and flushing a truck load of money down the drain, I discovered the hard way that very few aftermarket parts are better than stock, most are worse. Unless a particular bike has a particular part that is of a poor design, in my opinion, you are always better off getting the bone stock bike dialed in perfectly instead of wasting effort, energy and money on aftermarket gimmicks.
 
yep good advice. if its stock and your wringing its neck everywhere....by all means look for more go. I always tease the young guys on the 450's with the 1000 buck aftermarket exhaust..." so you can hold that flat out everywhere can you?"
 
I put a set of V Force in my Mag 250. I had been running the short factory reed block with Boyesen. I got my V Force from Huskydogg.. they were obviously modified "other bike" set up.. did not fit very well..had to massage the pyramids so that they would fit.. eventually got them to fit..the bike has noticeably more mid and up power.. once it gets underway..it really takes off.. there is no bottom end missing.. was it worth the work..?? I would now buy a set from Andy..no headache to install is a bonus.. Mossbarger on a 250 is too big...the air speed is lost ..and so is the HP.. Mossbarger on a 430..perfect..!!
