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 The previous version was outdated and no longer supported.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

New Husky owner, coil question

you will have to look up the exact spec but yes the advance should be much smaller...a few millimeters
 
Ok. Quick update. I got the coil, adjusted the timing as instructed, cleaned up those ground points, and got the old girl started.

I just used one of those baby booger things to put some 50:1 in the carb.

When it fired (after several kicks) it sounded pretty good, then I goosed it a little and the throttle stuck.

RPM's got a little crazy so I tried to goose it again to get them to fall.

That didn't work, so I tried the kill switch, which I apparently put back together backwards because it shocked the you know what out of me.

Anyway, it sheered off the flywheel key and died.

Can anyone tell me the flywheel key size? Also I assume a carb cleaning is probably the remedy for my throttle issue.

Thanks guys!
 
is your throttle working smoothly and smacking shut when you wot it and release? if not you have to start there...husqvarnaparts.com has them and you should have a few as spare. i dont think they really should shear unless you dont have the flywheel torqued right, as the key doesnt hold anything, its just a timing reference....have you cleaned your carb recently? if not thats a must do
 
Yeah, the throttle seems to snap back to the stop firmly. I have no idea how long this bike has been sitting, so I'm sure the carb needs cleaned and I'm thinking maybe the needle isn't seating properly when the throttle is released.

I'm sure the flywheel nut wasn't tightened fully as I see now it should be 70lbs. My mistake.

I think I can get a new key at Atwoods here in town for pennies if I know the correct size.
 
before reassembly lap the rotor to the crank to assure proper seating
as a side I feed a wire from the ignition mounting screw to the coil mounting screw for positive ground, it can be a small wire, 16ga wire works fine and fits in the loom casing if your patient
 
good point about the lapping primo, i forgot to mention that....keep at it, sounds like its almost a runner!
 
Sounds like a sensational runner to me:lol: ive just picked myself up of the floor from laughing so hard.... I wish we could have a pic of your face when she pegged out at max rpm!

years ago we had an old six cylinder engine sitting in a shed and ol mate turns up and wants to buy it!.

So get battery, get a jam tin of fuel, tip some down the carb and cross the starter terminals..... roar, she starts! the exhaust flame from the straight manifold lights the jam tin of fuel (panic ensues), mr mc hanic on the throttle jumps in to grab the tin and kicks it by accident sending wall of flame across the shed:eek: (outright panic). the throttle pegs out on full and the motor is roaring away sending a fine jet of oil from the gauge sender straight up to the roof spattering everywhere!
took us hours to calm down from that one.
 
So, I figured out the throttle problem. Carb was sucking air because I didn't have the tank on.

I got a flywheel key that works and put that back together, this time torqueing the flywheel bolt!

Put the tank on and she starts first or second kick! Sounds good to me, but I'm still worried about running too lean.

What should my plug look like and how long should I run it before I check?

Also, I'm leaking gearbox oil at the sprocket. It's this just a sealed bearing?

Thanks guys, and YES it was a SHOCKING experience! For now I'm just pulling the plug to kill the bike.IMAG1180.jpg
 
for now, try shutting the bike off by letting the clutch out while holding the front brake and it will just stall easily, or it will usually die quickly by putting the choke on. you dont want to just pull the plug cap off, as it hurts and is bad for the ignition..
the best way ive found to know if you are lean or not is to go up a jet and see what it runs like..plug reading is tough, and requires running wide open...some say its not a good way to check these days with additives in fuel (ethanol)
 
Thanks Justin, I'll stall the bike as you suggest until I get the kill switch lined out.

I haven't adjusted the shifter, that's where it was when I picked it up.

Any suggestions on sprocket bearing replacement?

Now that you all have seen the bike, and heard what I'm into, did I get a good deal for $200?

Obviously I haven't tried to clean it up any yet just focusing on making it a good runner for now.
 
That's the best $200 you've ever spent.! what a great deal...
Re jetting. if it didn't die in the pegged throttle event, its probably close.

when a bike is lea,n it is real smooth and feels like the fuel has been turned off. get it going and then when its warm and idling, turn the fuel off and let it idle till it runs out of fuel.

it will idle away for a bit then start to rev up a tad as it runs out. it gets what is called "run on" just as it dies from lack of fuel when it revs up and down.

If your bike is lean in the needle jet (1/4 throttle to 3/4 throttle) it will feel like the fuel tap is off and becomes real smooth and start to run on when you shut off the throttle and make pinging noises:eek: if you think this is happening you can drop the clip on the needle to richen the needle range ( lifts the needle up and lets more fuel in).

hope this helps... can be hard to describe jetting....
 
i think it looks ok for 200 bucks....
however, right now, you need to make the decision to stick with it...or move it along...
its hard to impossible to baby a husky along. but thats a good model with some good parts. looks like it has the original ohlins in the back, would be wise to get a rebuild kit and have someone freshen them...they are good! bike looks like it just needs alot of cosmetic work. i say go for it and enjoy it. that big 430 is versatile and will run as hard or easy as you want it to...maybe do a compression test so you can determine the true health of the motor. parts are regularly available for your bike
 
take your sprocket off and see if theres any play in the countershaft. if the bearing is tight, you can just get the seal/plate that is held on with 4 screws. the forks are super easy to take apart so do a good flush refill and they will feel a ton better
 
Thanks guys. Suprize, I'm trying to understand your explanation for figuring out if it's running too lean.

You said if it didn't die during the pegged throttle event, it's probably close. Does that mean it's probably close to being right?

I tried shutting off the fuel during idle today it idled probably 30 seconds, then started to rev up. I hit the kill switch before it died on its own after a few seconds of pretty high revving.

Does that sound right? Sorry I'm not more knowledgeable about this. I appreciate everyone's help.
 
you want to stop running it out of fuel...a two stroke needs fuel to lube its main bearings, piston, cylinder, and rod bearings...when it runs out of fuel and starts to rev, there is probably some wear going on.
 
seems like it should idle longer than 30 seconds, I have ridden on a closed fuel longer
take the carb off and check the main jet, slide, needle jet, jet needle and pilot, what is your altitude
safest bet is to start at a known base line then adjust from there, less chance of damage that way
 
If there was an issue with fuel flow it would have died when it was stuck open so I guess fuel flow is ok.

now you know what a lean two stroke sounds like, you don't want to hear that when your riding. as Justintendo says, low fuel means low oil for the engine. two strokes are greatest risk of damage with a closing throttle from a top gear blast wound right open. they are hot and as you close the throttle, you restrict the fuel going in even though the engine is still at a high revs so that's why I tend to feather the throttle on an off as im slowing down from a high speed run to keep fuel going in (unless you jam the skids on and lock the motor down fairly hard.)

so back to jetting, as you ride the bike, take note at the different throttle openings.. mark on the housing, 1/4 open, 1/2 open , 3/4 open and ride along at each setting in say 3rd or 4th ( you will be humming along in 4th) and try to listen to t he motor for those "running out of fuel " type noises. also check for surging and or 4 stroking (like the choke is on...means its too rich) if its bapping along fairly happily, its probably close enough for you. note here that 2 -s that are not "under load" (like at even throttle) tend to sputter a little bit and miss so don't be too concerned.

As 2P says, have a look inside the carb and write down all the jet numbers (the little brass things with holes in them) and the needle will have a no too. if your like me you will need a spyglass to read them.
everyone on here can tell you if the jet sizes are ok.

My guess still is that its a runner and is probably ok for naffing around on until you get a bit used to it and want to explore it more.

make sure the airfilter is clean, oiled and greased and the gearbox has fresh oil and then give it a run in the hills. you will love it....
