1986 HUSQVARNA 510TC AIR COOLED 4T QUESTIONS

[can]

After about 6 sem stators I tried an electrex stator in my husaberg and it works great. I currently have an sem that is miraculously still working in my 1984 510

Yes I had the same experience with SEM stators when I raced a 89 TC regularly in the early nineties, three failures I think. May just go the electrex route when I complete the current rebuilds. Did you need a different coil unit to go with the electrex ?

All the wiring is exactly the same, just plug it in to existing coil and the bike starts right up.
Speaking of cdi coil units - I do not recall one failing in any bike I have ever owned.

Hey Daftmate. Thank you for the post and pictures. Very helpful.

I can see now that your 89's are inboard stators and your flywheel rotates counter clockwise.

My 1986 510 has a flywheel rotating clockwise and an outboard stator.

After hooking up the wires in various configurations I got a pretty decent spark off the plug.

The carb rubber manifold attaching to the engine has disintegrated and I need to purchase another one.

Does anyone know of a place where I can get a rubber manifold for a 1986 510 with a PHM40 Dellorto?

I noticed the later water cooled 610tc was using a PHM40. Do any other years or models have the same manifold boot?

Cheers,

Daftmate, advance is a function of engine revs, not direction of rotation. The advance is controlled by the CDI and should work fine. However you are correct that you can not use an inverted stator on a normal flywheel arrangement. Direction of rotation is important for SEM stators.

try sudco.com for manifold

My engine goes clockwise too promise, the previous picture of my flywheel was taken to show the stamped marks correct way up, its actually upside down. Sorry if threw you, maybe this picture helps. Of course when I'm talking about direction of rotation I'm looking straight at the flywheel side. DM

Good debate this ! Yes the amount of advance is proportional to engine revs but think about the direction in which the electonics will apply the advance. Isn't this different in inverted and non-inverted systems? I still can't see why the direction wouldn't flip if the same stator was placed a different way round relative to the crank/flywheel. Spent a few beers debating this late night at my local and we couldn't agree either so pls. understand if my logic is still in the bottom of the glass.

I fitted a hpi universal 4 stroke ignition to a 74 XL 250 motor which is also inverted. I had to rotate the rotor by 180 degrees pretty much to get it to work,compared to the instructions..a lot of push starts before I got it running I can tell you!
have you tried push starting? If you aren't familiar with starting these and if the jetting/carb isn't 100% you will never start it with the kicker.I wore a hole in my shoe learning to start my 510...but it push started easily.

Thanks SA63!
My next step is to get a new rubber manifold for the Dellorto PHM40. Mine is shredded. I also need to clean and rebuild the carb. I'll try kickstarting it then but may take it to a hill nearby just to get it to fire.

Once It fires and I can get through all the gears I can begin the teardown and order parts.

It looks like the mid 90's TC610's also came with the dellorto PHM40. Does anyone know of other years/ models that may use the same manifold? The one for the 510 is pretty steep...

Are you trying to start it with no air filter? Makes them very lean and hard to start cold.

Thanks Motosportz! I was kicking it without the carb and starter fluid just to confirm things are in working order. I was just going to kick it without the air filter but I will make sure I have the whole system set up before trying.

This model is noes to me. I have an XT500 and a '79 390OR so any beta on starting this beast would be much appreciated. I'm still refining my technique on the XT500...

What year? I have an older TT500 and it is super ES to start. Roll it over TDC with the manual comp release and one nice kick and shes lit.

Wow beautiful!

Mine is a 1980 with CDI. My compression release lever is being repaired. When I find TDC she starts 1 kick no problem. but finding TDC is sometimes a mystery without the compression release. I thought I wouldn't need it but apparently it helps position to TDC?

Cheers,

 

[Motosportz]

yep kick it EZ til it stops (comp), pull the lever and roll it slightly past TDC and one big smooth kick and away you go. I can start it in tennis shoes. Is kinda shocking how EZ it starts.

 

[suprize]

if it doesn't fire up after 4 or 5 goes, pull the decomp, 4 strong kicks on full throttle and try again. note...don't touch the throttle, put your hand on the cross brace so its nowhere near the throttle.

I have a OWNER'S SERVICE AND TUNING MANUAL for WXE - wmx 510/90
Its another model year, but about same engine.
Maybe it helps....

I have a 1987 TE 510 with the external mounted stator ... Could anyone please tell me what stator i will need ? Part # ect ... I seen where the external stator & internal stator will NOT work in both applications . as 1 has winding that go clockwise & the other has winding that counterclockwise .. or something to this nature . Is there any truth to this ? Thanks for any & all help

wow, really old thread to dig up..might have been easier to just start a new one asking this question
