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 The previous version was outdated and no longer supported.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

83 CR500, here begineth the lesson

Well I dragged it out from its lair again making sure I have a bag of frozen peas handy this time. I've checked it all through bar ignition timing and it all should be good. No luck though. Backfires on the first kick then nothing until its stopped sulking in about 20 mins then the same. Carb is all standard settings as should the timing be, all the electrics check out according to figures. I'm a bit stumped, I think it must be spark related though so back to the timing again I guess. I just had this on the KTM with an over large pulsar coil gap, got there in the end, just a case of persevering.
Looks pretty in its nearly finished state though, would rather have an ugly bike that ran at the moment.

Bike looks fantastic! What about rolling down a hill and try a 2nd gear push start? Or move the timing a C hair more past TDC

Thought about a push start down hill then thought about pushing it back up again. I'll have a look at the timing.
I remember this with my rebuilt 370 stormer, it just would not start after hundreds of kicks, then it suddenly started and did so ever after !!!
I'm beginning to suspect demonic possesion.
 
the backfire is a clue but unfortunately, my name isnt Holmes..nothing inthe exhauzt? i spent 2 hours trying to start the wipper snipper only to discover some wasp had called the port home! float is good and plug is wet? no jokes...reeds sealed ok. tried another plug? iknow all this is obvios but helps to get the mind ticking...i had the same with the 400 and it just fired up without any real changes. keep at it as the bike looks fantastic.
 
This post is about SEM stators.
I have found that if the stator internal wiring is getting a little sad of if you send your stator to some Knob in Spain who rewires it wrong then you will have a very weak spark at low revs.
Which is NOT what you need when trying to start a big bore.
So I mucked around and found this cdi and coil that need LESS voltage to create a good spark at low revs.
The cdi should be a non advance one or you will have to set your timing to suit . Example , 2mm at full advance.
I check my timing with a battery powered strobe.
I am running these on all my Huskys [ sacrilege I know ] and never have a problem , I also carry a spare but have never had to use it.

I think she's sulking coz you've painted the exhaust white and left her undressed without her front mudguard....:D

Only joking.....Lovely bike.

2003 525 exc out to 540, knight flatracker seat, all the engine mods to keep 60+hp at the wheel from turning the motor inside out.
Been playing with that and igoring the Husky since it refused to start and then fell off the stand. I 'had the right hump' as they say.
Thanks to Larsa's pics I am ready to start on it again.
Got a weeks work before I can start proper but started the fork brace and investigated the motor. As you can see from the pics I was getting too much fuel. I need to adjust the kicker to get more revolutions and lay off the gas. I really want a stronger spark though. All the electrics check out ok but I might start a thread to investigate electronic options.
I hate the tyres too so going to pop them off and go for more of a supermoto tyre.

Is this the supermoto look you are after??
Here is my 88 430XC as I bought it it has original hubs laced to Morad rims with bridgestone BT45 110/70x18 fr & 140/70X18 r, though the chain kisses the edge on the rear! I have a freindly MOT station, I have since got some original size wheels from Andy at HVA
 
Well it was a long time ago but I always found the trick was choke on, petrol on, lay the old girl on her side until fuel started to dribble onto the crankcase, stand her up, a couple of slow turnover kicks on the started, then get the kickstart to the point where it bit and then the usual give it a good kick. Believe it or not always worked for me.
 
Many thanks for all the advice, think a weak spark is the cause. Going to finish off all the mechanical details, chain guide, fork brace, etc. Some good ideas to improve spark thanks. Im of the mech school, so glad of electical advice. This week though got rebuild and porting of a pair of Rover V8 heads, fixing an Audi gearbox with a sheared selector fork, removing a Beryllium evaporator from a nuclear fusion reactor and some 'brown laning' on the KTM to be done. Going to be a busy one !

Thanks for these, I'm a proper dunce with electrics but found similar on UK Ebay. They seem like a simple solution so will be investigating for sure.
 
solid shot can be a little exciting for men our age.... i prefer the 44 - 440 lever action the old man gave me. sends a basket ball of lead slowly but steadily toward whatever you point it at then all hell breaks out at impact and whatever you hit looses interest in everything very quickly! its a wonder you dont hear it at your place, only 10,000km away... its loud!

Don't think I got the beard to fire a weapon like that! I'd like to use that on the Husky when it don't start but I think it would just make it angry and snarl in my direction before savaging my ankle again !
 
You could always just beat the bars***d to death , sorta like on Faulty Towers.:D
A lot quieter than a shottie although the screaming doe's attract attention.


Interesting thought.
If you used a 4 stroke CDI [ with inbuilt advance ] and set the max advance at 2mm BTDC then would ? the bike be easier to start.
The starting timing would be 1mm BTDC or thereabouts [ you know what I mean ]
May not kick back at all and be easier to start. [ PE suzuki's are like this ,for the girl riders probably ]
I personally like the decompressor valve and my foot does too :thumbsup:

Thanks for the prod. Just got back into it after the non starting day a while back, when I kicked F*ck out of it and it just laughed, backfired and then fell off its stand as I was eyeballing it from the other side of the garden. I got the fever back this weekend, bent the brake lever back, got a new ignition coming with internal rotor developed with Electrex, got some +5mm lock stops and the fork brace is back on the mill.

Ok, try this, take the plug out, if it wet or black toss it, kick it over, put a new NGK BR8ES. If bike wasn't flooded, put it in 3rd gear with gas & Choke on & rock it back & forth counted to 30. Gas Off along with choke off, put the bike in 2nd gear & roll it backward til it stops. Now try NOT
to move the bike forward & put the bike into neutral, take the kicker & move it down about 1/4 stroke, you should hear the compression of the piston as it moves partly thru stroke. Let Kicker go back to top & give it a real good kick, if you screw up & don't kick it well, back it up in second again & move the kicker partly thru stroke again.

This procedure get the piston just a hair past the compression stroke, the best position for it to start, just like when you start a big bore 4 stroke single. I've been using this starting procedure on my 84 500CR & 85 510TX & they been starting on the 1st kick as long as it's a good one.

Thanks HJ, I will take that advice, just want to get a decent ignition to give me a good fat spark. I hope to be sorted sooner rather than later so I can get some hours in before the winter then I can do the odd clear and frosty ride out with no holds barred ! I remember my air cooled 2 strokes always flying with a cold charge of air and some good cooling on a winters day.
