Bueno, verifique los diagramas y estas en lo cierto. Entonces quedaron pocas opciones. Se quemó la ECU, el rectificador está dañado o los cables de alimentación de la ECU no estan bien o mal conectados. Viste que la ECU de la valvula lleva alimentación 12V?

simplemente desata los cables de la valvula, arranca la moto y ve cual cable empieza a Estirar al acelerar. Ese es el cable que va hacia atras de la valvula. Normalmente lleva un resorte. El otro cable lleva Tuercas para el ajuste y va hacia el lado delantero de la moto. Espero que te sirva la ayuda.

Revisale si la valvula de escape está bloqueada, o si conectaste al reves los cables
De acero de la valvula.

You need a flywheel removing tool. Seguramente un taller de motos te lo prestaria.

ahi te deje una pista en tu post. Tiene que ser la bobina o algo por ahi. Seria una lastima si es la ECU ya que no se consiguen tan facil. No hay muchos repuestos usados en Iquique?
Todas las AR de aqui las importaron via Chile.

maybe that spark plug is dead already? Did you try to change it? looks like the problem i had with my AR. didn't really get sparky even revving up the thing.
could be the coil, the plug or the ECU. you should be able to get a coil that is similar to see if it solves the problem?

I once got informed that ECU and flywheel must match... don't know if these could be a problem, too

I had that same spark problem on my AR. And first i thought it would be my fault Because i had the gear potetiometer not correctly installed. But even by fixing it it made No diference. I manged then to clean the pickups from their rust, and so she startet again on First kick. Maybe you got a simila...

Estoy a la vuelta. :-) Reconozco tu problema ya que ak tengo unas AR que me lo hacen dificil. Pero por ahí nos Ayudamos uno al otr...

That looks like it had done its job... Rebuild

I couldnt get the impeler off without using mayor force. The shop maybe tried to
Take it of, too with no succes. By turning the impeler with a tool, the shaft startet to slip
Inside the now broken gear. Thats why i decided to let it that way and just install the new gear.
Have some mercy AR

Yay!
Took that clutch cover to my good old buddy and he made a new waterpump gear
In no-time! Made of some bakelite and reinforced with a small bronze ring
Lets see if it cracks again. Now lets play seek n hide with the police again.

Maybe the piston rings didnt survive that last one? Had a mk1 That seized because of oil indicator faliure and the rider could stop The engine right before it blocked up. After ading some 2t oil and cooling Dow it rant with that same noise as yours did. After 2 months of severe Weather and WOT rides...

So for a guy who like me who lives in the middle of nowhere, what would be
The solution for my problem? Build a new one?
