Let the "FUN" begin. Toe breek die Yamaha

[woody1]

Kom ons se pa het probeer maar gefaal... Vir R 80.00 het ek die kans gewaag, maar ongelukkig is 130 ohm ver van 300 ohm af of die CDI is ook kapoet.

Gelukkig kom daar nou alles in die pos en tot dan gaan seuntjie lekker nek skiet by sy tjommies.

Geniet hom Pierre.....

kan jy nie 'n paar resistors in soldeer nie? Is daai coils in para of serie?
Jammer vir die newbie vrae, my yamaha was in JAPAN gemaak nie CHINA nie so het nooit sulke failures gehad nie

Glo nie extra resistors gaan werk nie.
Die 300 ohm wat benodig word sal opgemaak wees van BAIE draaie dun koper draad op 'n spoel.... dit sal dan meer krag uitstoot soos die magneet om dit draai.
Die 130 ohm wys daar is minder draad op die spoe l gedraai en dus induseer dit minder krag wat die CDI nodig het om te TRIGGER.

Laat die ou tegnikus nou die ingeneur moet reghelp.

Go check startline.  I am sure they can sort you out with everything on that motor.  See attached pdf, section 66  http://www.startline.co.za/images/Startline_Catalogue_2017.pdf

Dis hulle wat die foto van die lig het wat ek soek, maar nie die lig wat ek soek

And he received OUPA SMURF boots today... Ja 'n laaitie van 17 wat size 11 boots dra van 'n ou man in PE. 

'tjek... met 'n hoofletter 'F'

Ek is meganies, okei?   
En selfs met meganiese goeters sal ek eers die ou tegnikus raadpleeg, ekt al geleer dit spaar my baie tyd en moeite op die lang termyn   

Daai maak baie sin, dink jy's 100% on the money 

[woody1]

Het Startline probeer...dinge is naby dieselfde maar nie presies nie.... plugs bv is verskillend... kan seker omgeruil word maar het met die ou XL 600 nuwe handelbar switches gekoop.. Was 'n mission om alles op die regte plek uit te bedraad.

Wag maar vir die goed om te kom van Duitsland.

Update time.

So the stator and CDI arrived.

So we started by replacing the stator assembly.  No spark ..shit !!!!!!!
Plug in the CDI... POP goes the 12 Volt fuse... shit !!!!!!

Moving into the new house so this project goes on hold.

In the meantime I search the web.  The CDI physically looks the same.  Even the plug is 100% the same but it has a different number on it.
Turns out that although the XTz and the YBR 125 share the same motor, the electrical parts are not 100% the same.  The YBR has a lot of fancy extra stuff like fuel gauge, rev counter etc.

Every now and then I would spend a few spare minutes looking at the wiring and try to see if I get spark. 

Funny thing is that it would spark once and then nothing.  Checked for loose connections, corroded connections, could not find any.

So yesterday with our FREE HOLIDAY I went out to the garage. 

First on the agenda was to take the chainsaw carb out and boil it in my favorite LEMON JUICE pot.
After this the chainsaw starts on the first pull... Very happy.

Then I went and sat in front of the little XTz  and I remembered when I did the restoration on the 1958 BSA Bantam I had a spark issue on the little cdi thing that it had on.
On the BSA I followed all the online instructions and wired it as per the info. We could not get spark and I decided to turn two wires around.  Well it sprang into life every time on the first kick.

So I had a look at the XTz.  The pulse coil has a green and a blue wire.  So I had it connected green to green and blue to blue.
No spark and maybe a little spark every now and then.

So I decided that I have nothing to loose.

I connected the blue to the green and the green to the blue.

Pushed the starter and WOW big fat blue continuous spark ...What a relieve.

I thought it is just a coil that gets exited by the magnet passing over it...does not have to be positive or negative orientated.

So we put it together, got some fuel into the tank. Choke on and start......ooooo shit.
She sounds like timing is out...sounds like an internal backfire.
But once the engine is running she runs smooth... only on the START she has this off timing cough.

Pierre took it for a spin to the garage to fill her up with petrol.  Runs fine... only the internal cough on startup.

Any suggestions.
Thanks

only the internal cough on startup.

Racing bikes en dragster karre is die timing so bietjie offset vir ekstra performance en dus grof op idle. Los hom so dit klink cool!!

[woody1]

Spares in South Africa....SHIT we get ripped off 

Yamaha quoted R 1700.00 for the stator assembly. Our stator is fine only the pulser coil was faulty, but you cannot buy that part by its own.
Yamaha price R 1700.00 and on backorder
Price in Germany R 785.17

CDI.  Yamaha South Africa. R 8000.00  Yes Eight THOUSAND rand.
CDI from Germany sealed with the Yamaha codes etc...therefore a genuine part  R 188.63.

Problem is not when it is running Chris... Only when you push the STARTER it sounds like a backfire.

Maybe the battery is a bit pap after the long time not running. Charging at the moment will check later today when I get home.

Dis blerrie mal, kan mens nie daai altenator by Midas koop? BMW maak mos nie altenators hulle kry dit by iemand anders.
