1986 HUSQVARNA 510TC AIR COOLED 4T QUESTIONS

My 1986 510TX, at Carlsbad Motocross track in 1992 for an SRA GP, note my rear fender cracked off. Acerbis headlight, full wrap handguards, plastic skid plate, fork boots, Swede flags, front disc guard, Hi-Flite seat, answer shorty silencers, Mikuni flat slide carb and my beater Dodge van.

Michel : DUCATI is better than SEM ? Which type of Ducati is that? More technical news please.
So many thanks

These tips were given to me by Claude Bailleux from Belgium who is a hva dealer near Charleroi.
The ducati ignition is the ducati ignition on 610/570 husky(95+).
He thinks it works better. It is sometimes hard to get a good used sem.
I've had problems to start a 510 whose SEM magnets in flywheel were missing.
You need to have a crankshaft with a normal flywheel not an inverted one ( not sure it works with that).
The black ducati coil (CDI)is better (2000+), because you don't need to keep all the electronic box
that are on top of 610 forks.

You can add an drilled hole on you crankcase and put the oil line.
One of my friend did that. Just need to take the oil plug ( 90-98)
with the oil filter.

Or you can find a bottom end or LC crankcases 90+ where they are thicker
at the place of the new hole .
In my motor I have:
- 350 crankcases 1990
- 510 LC crankshaft 89/90
-84 gearbox
-95+ 610 ducati ignition

About clutch, there's a little change with 1st LC with gear starting , so you can keep all
the clutch if I remember, except the clutchring which is different since 87.

About oil cooling system, there's 2 threads started on café husky.

I told you...
LE MILLEUR !!!
Merci !!

for my twin TC I m using the whole body of a TE 610 6 speed from '98 with a TC 500 aircooled cylinder, piston and head from 85/86.
My buddy was making a bushing for me to connect the pistonbolt to the 610 connectionrod.

yeah ... everything looks fine ... but the green biketights ?!?!???

You can tell us Jens....no one cares here

Has anyone tried these units on ebay? http://www.ebay.com/itm/NEW-CDI-TM1...Parts_Accessories&hash=item3a89332c6b&vxp=mtr

Looks to be the same unit as on my '86 510.

It also lists these models as using the same unit:

HUSQVARNA TE 410 / 510 / 610
HUSABERG FE 350 / 600
KTM LC4 400 / 600 / 620

Not sure if it is improved over stock.

ouch ... this is very expensive ... I think

Yes extremely expensive. Much better off with a HPI CDI and coil from Belgium. They include rev limiter I believe unlike original SEM.

Thanks for the beta PEZberg.

I checked out their site: http://www.hpi.be/applist.htm

To my understanding they only support back to 1989 Husqvarna's. Mine is a 1986 and I believe it has a inverted SEM or something that will not accept a standard rotation flywheel and stator?

The only system I have found so far that directly addresses that fact is the power dynamo system here: http://www.powerdynamo.biz/eng/systems/7129/7129dcmain.htm

Very expensive but I have very little into the bike so far and as far as power and reliability go may be the best way to proceed?

I have a friend I convinced to buy the MZB system for his XT500 and it seemed to be a very good quality system. Improved spark and starting and can run backcountry lights and HID's. $650....

Can anyone explain what the inverted SEM system is and what it does?

Is anyone making the up-tite husky style of oil cooler anymore?

Hello Gentlemen,

Just tearing into the Electricals today and could use some help identifying the parts and wiring setup.

http://www.flickr.com/photos/19691101@N04/

It looks like the previous owner replaced some parts but I am unsure if they are for the newer models and thus would not work.

EDIT: THERE IS SPARK! I hooked up the double yellow wire to the orange from the SEM/CDI and I got a spark. However Kicking it over several times still could not get it to rumble with starting fluid.

Any help with identifying if this is the right unit for this bike and what the wiring set up should be.

Cheers

Also looks like the coil is mounted using the wrong screws. They have been shaved off.

The rotation on the flywheel says clockwise and has the following stamped in it:

k10/190ec 02

w646

There is another thread on this forum freewheel boy. Search for it. I repost some photos below..

HPI website is wrong as they do have ignitions prior to 89 for the 510 four stroke. Electrex World make the stators HPI offer. I believe the photo they show of the inverted SEM replacement stator is not correct as the mounting plate is wrong diameter. However I have been assured that Electrex World does in fact make the correct stator and mount. If you want to purchase off someone who has a 510 and will confirm the Electrex World will fit then try eBay vendor mrclassicford. Lee sells ignitions and other things for Husky's in the UK.

I am rebuilding a couple of '89 510 TC's. The SEM ignition systems are the same on both 89 bikes with stator sitting inboard of the flywheel rather outboard as shown on your bike.

I can only think this relates to the 'inverted' term you asked about, most bikes have a set up like the 89 so I would call yours inverted rather than the later ones. Engine rotation is the same across the actual engines (hopefully) but moving the stator outboard also has the affect of puttting on the stator in the reverse direction relative to the crank. To my thinking this will affectively reverse the direction of rotation of the magnetic field produced by the rotor relative to the stator.
Then if the above is correct even if you managed to get an non inverted stator fitted to an inverted flywheel system and timed right by shifting mounting screws then the auto advance would work the wrong way. ie as the engine speeded up and wanted more advance it would in fact get more retarded.

As I said I've not worked on anything earlier than '89 so am just putting this forward as a possible explanation of what 'inverted' meant on you post and some thoughts on possible consequences when swapping bits around various vintages. Appreciate input from more experienced forum members as I have a feeling you guys have already been through all this. Have fun !

Here are some more pics of the details on my bikes:
