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 The previous version was outdated and no longer supported.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

All 2st My ice machine dynoe'd. No husky but it works=)!

Pretty exciting Johnny. My Spanish is a little rusty though, so I couldn't understand much.
What was the peak power before and after the pipe and needle change?
 
Hi Johnny !
VERY nice number, particulary the torque number.... very nice powerband.
How much compression do you have and what type of dyno ?
Do you have run a drag race between the 500 and your WR300 ?

I am in the process of rebuilding my WR300 top end (small main jet and -5 degree = beginning of seizure.)

Hello As a reference a standard CR 500 1999 gives around 48 BHP on the rear wheel. The first dynorun gave 59,2 horsepower and 77 Nm at the wheel. Then we changed to the handbuilt pipe and it started giving power at the same revs as the PC-pipe, but peak power was 62,8 BHP and torque is around 80 Nm, and all this at 5800 rpm only. I'll get the dynosheets as soon as he scanned them for me. We did only WOT runs so we didn't laborate with the needles, but i know what works good;=). If i had a 178 mainjet we would get just over 63 BHP as it was slightly rich with 180 and slightly lean with 175.

Hello Francis! Long time since we heard from eachother. yes, i'm very satisfyed with the power as i've done the porting myself and put the whole concept together.
On the dyno i had a 63cc combustion chamber, and cylinder pressure while kicking it with open throttle was 11,75 kilos. That would give 173 PSI if i count right. With the 66cc chamber i reach 165 PSI which is enough. No detonations at all with regular 95 octane fuel and 3% oil. I took a short run with it and it is soo strong! I have to be careful, it,s so agrressive once you open the throttle just a little bit. I run 14/41 gearing and it kicks up on the rear wheel in 4th on half throttle at 3500 rpm. I actually changed combustion chamber to a 66cc to make it slightly "smoother" from the bottom and to get a better overrev. Another thing is that i use a high volume pipe now and it dies at 6500 rpm, but the cylinder is ported to give max power at around 8000 rpm, but i'm quite satisfyed as it is right now!
I haven't drag raced it agains the 300, but the difference is BIG! The biggest problem is to keep the front wheel down!
I don't remember what the dyno name is, but it's the type that works with a constant weight that needs to be accelerated, so i guess it's like a Dynojet. Looks about the same, but i can check. His dyno is also known to give quite low numbers when compared to others actually. Anyway, it's nice to know and not here a lot of speculations. now i can say about 70BHP at the crank=).

Ah, ok, so you,ve been running lean my friend! Sounds like a 180 should be good maybe? How many hours do you have on the 300? Any piston change yet?

Hi Johnny, i have 177 hours on my 300. Never changed the piston. Exept for the small seizure (by my fault, i have run a 172 main instead of the 182 i normally run in winter)... at -5. The cylinder and piston are really nice, no sign of wear except where the small seizure was !
 
Wow! That,s good! 177 hours! My 300 runs like a champ too. Great bike. Nothing broken except from my own mistakes. I have only about 85 hours on mine. I've been using the 500 for the street this summer and the 300 for woods. How is everything going with your cars? Any new projects with the Saab?
