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 The previous version was outdated and no longer supported.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

Husqvarna
B Class
Hello people, I would like some help with tuning my bike as it is such a labor to start it makes me not want to ride. When I'm riding with my e-start riding buddies I don't want to shut her down because seldom will she start back up on the first kick. Once she is running and the clutch is behaving, it's a feeling like no other bike, with the constant reminder of "geez I need better brakes."

Anyhow, the specs for the bike are:
All new bottem end bearings, oem bore and mahle piston. Leakdown tested overnight and it held 7 psi
Carburator has been taken apart 7+ times + ultrasonic cleaned.
32:1 with honda hp-2 and 93 octane pump
1.8mm BTDC W/ SEM ignition
(Tried 20:1 with some cam2 110 leaded and I think it was running pig rich, I gotta try again once she cleans her act up)
Dynoport exhaust with Answer silencer
(Recently repacked)
New UNI airfiter, lightly oiled
Sea level to 1000ft above sea level riding area.
2.5 slide
6DH20 4th from top on clip position
45 pilot
400 main
166 R-O nozzle
Air screw 1 1/2 turns out


I belive I have the starting procedure down pat. Slowly kick the engine over until your at TDC, make sure the kicker is as high as it will go and still engage, then jump and kick with 100% effort. I find it very difficult to kick it with my left leg. It's also very difficult to kick with my right leg while holding the throttle. (It feels like Im playing a game of twister on the leaning tower of piza, with a little attitude from the bike mixed in. Not fun.

On a cold start with choke she will make one combustion cycle then stop. Not a backfire just not enough to spin to life. After this it's choke off and WOT while kicking. This is the only way my bike will reliably start.

If it's a hot start I'll kick with WOT and it usually start up withing 1-4 kicks,

It seemed to coldstart better with the 110 octane.

It seems that on my ride when it was 80F out she was not fully responsive thru the rev range falling flat about 2/3 to 3/4 of the way thru the throttle range. My last ride where it was cool and later on in the day probably 60F out she was the best behaved ever. 3rd gear power wheelies and very responsive. Sometimes a slight hesitation at the 1/2 point which would happen when the throttle is slowly rolled on. If you wack the throttle past with any authority she would respond nicely.

The above symptoms are not what I'm requesting help (it would be appreciated however) for, I can live with this and slowly tune it out. The starting is where I need help as I am hurting my self and it's grueling starting her up.

What are your specs for the carb on a liquid cooled 430? Should I try a different pilot? Should I try tuning the airscrew?
Should I just wait until it gets cold enough for my bike to be on good behavior with the carb settings.

Sorry for the format this was sent from my phone.
