• 2 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     WR = 2st Enduro & CR = 2st Cross

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 The previous version was outdated and no longer supported.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

250-500cc Anyone making a 300 pipe yet?

I'll bet you that pipe is for a WR250...

Maybe, but I doubt it. Kearney's bike has tons of mods including a GG 300 dome piston, digital ignition, custom airbox among others. It wouldn't be out of the realm of possibility that PC did a custom pipe for him. He's been seen practicing at a track that we use. I'm hoping to run into him one weekend to get the whole poop on his bike, especially the pipe.

A little secret about after market pipe manufactures.

Most all 2 strokes after market pipes made by anyone of the after market manufactures uses the SAME PIPE STAMPS! the only things changed are the tail stingers, the head pipe and any mounting tabs.

If you look at the stamps there only 4 stampings plus the stinger and header.

So a Suzuki RM pipe is the same as a Honda CR pipe as is the same as is a Yamaha YZ pipe as is a Kawasaki KX pipe as is a KTM SX pipe and so on......

All they do is move the stamp plates just slightly and so they wrap the frame better.

Truth is I'd be almost willing to bet that the new Husky 125 uses the same stampings as the old Husky 125.

I've heard that before regarding the stamps for pipes. Makes sense from a business standpoint....

I emailed PC :cool: yesterday, but no response yet.


Mark,
let me know about that 250 pipe you have. Not looking for a handout, but I would at least see how it fits and performs.
 
how would you account if the pipe wrapped around the other side of the bike ?? do all the bikes pipes exit on the right ?? that would make the standard stamping unworkable if some exited on the left....... I'll believe it if somebody can show me some measurements. just hearsay for now........

1995 - 97 Husky CR 125 and WR125 wrapped around the other side and that's one of the reasons only dynaport made the only aftermarket pipe here in the states.

All the other pipe manufactures stamps were for the other side.

Oh ya Glenn's WR300 Pro Circuit pipe is the same pipe used on the WR 250... if that's of any help.
 
Pipes are made based mainly on port timing. Later RM and YZ 250's are so close from that stand point that they could both just about use the same pipe, if they were cut to fit the frame. Which, looking at how they are routed would be a lot different either.

So most 250's are going to run a pipe that's very similar in cone dimensions. Slight variations in section lengths and diameters will be the main differences. Header and stinger sections will probable be the most, if not the only dimensional difference.

Most after market pipes are made from two stamping, one for each side of the pipe, welded together then cut into sections in a fixture. The section are rotated and fit into a welding jig and put back together, like a puzzle.

I don't know for sure, but I'd bet FMF and PC make all their 250 / 300 pipes from the same stampings, which I think were all done at the same stamper at one time.
 
pipe

lots of don't know and i bet........a lot different from the karting world.. 64 gores in a pipe. although a much higher state of tune. :eek::eek:...

ALL after market 2 stroke dirt bike pipes are made from the same stamping for reasons posted above.

WOOPS THIS JUST IN!.... Eric Pirie from P3 just called me and said the stock Husqvarna WR250 and WR300 pipes are indeed different... we were told by a local dealer that they both had the same part number! MY MISTAKE SORRY
 
I just got off the phone with Pro Circuit. They confirmed that they've been working with Wyatt Seals to test different stampings for Kearney's 300. They expect a commercially available version very soon, perhaps within a few weeks. Gerald Jones of Upstate Cycle will be at the GNCC this weekend and plans to get the poop on Glenn's PC pipe... how he likes it and if it's the final version.
 
If you guys really want to know something about pipes.
http://tsrsoftware.com/pkg-order.htm

The guy who designed this software is a friend of mine from way back when. He did several custom pipes for me when he was building them himself and they were always better than anything that was offered "off the shelf". It was pretty amazing watching him do the pipe layout based on my particular engine and riding requirements. He just sells software now but I bet there is a wealth of info in there is someone wanted to spring for the package.

Just curious, but what does the software actually do? Does it produce pipe-stamp die dimensions or cad-drawings? Kinda hard to tell from the website.

By the way, I spoke with Gerald Jones on Monday about Kearney's 300 pipe. Glenn had a terrible weekend and lost an engine after two laps. Neither he nor Wyatt were in a talkative mood at the GNCC so info about the pipe was scarce. Gerald did mention that PC is close to finalizing the commercially available 300 design which is what PC told me last week. Hopefully within a few weeks.

so it is obviously different than the 250 pipe as they already have that. :excuseme:

Yes, that's what I was told via phone conversation by the folks at PC... that they were working with Wyatt Seals on different pipe stampings to see which delivered the best power.

I haven't seen all the programs myself so I can't give a definitive answer. Cad drawings maybe, die stamp dimensions I kinda doubt it. The pipes that TSR produced were hand fabricated for each individual bike (they did make production runs for some manufacturers) so I think that that the software does the calculations for head pipe, mid pipe, reverse cone, total chamber volume and stinger based on the inputs for ea. individuale bike and the riders needs. The only reason that I brought it up is to point out that there is some real science behind pipe design and "off the shelf " pipes don't aways capture all the possible variables.
In essence the 250 and 300 pipes are or at least should be different.
