Suzuki dr 125 sm fi light

Hi and welcome to FixYa,

Initially, check for pulsating voltage on the black/yellow wire from the magneto to the ignition coil. Additionally, temporarily disconnect the black/yellow wire to the ignition switch.

Perhaps a wiring diagram would be of additional help.

Good luck and thank you for asking FixYa.

No! It will not work on your bike! Save yourself some major grief by sending it to me! :thumbsup: :lol: But seriously folks... it will work great once whatever jetting changes that may be required are done. I'm thinking you'll have to do some throttle cable rigging and possibly adapters for the air boot and/or intake manifold. I have no experience with this conversion so I'm just assuming. Taking the carbs off for measurements would answer all those questions. Certainly a doable project and a mass improvement over the vacuum slide Mikuni!! I have every intention of doing a project like this once I'm back in my home state of Michigan. Just in my initial thought process I believe I would pick the 39mm carb over the 41mm carb. My primary reason would be to maintain and/or improve low end. There will already be a marked increase in top end even going to the smaller bore due to the superior flow design of the FCR carb. Good luck in your project.... I'm jealous! If you ever think of not doing the project for whatever reason I'd be interested in buying your carb

could be stator or the coil or cdi box

SOURCE: removing the carburator on a suzuki drz, 125.

It is quiet easy, you remove the seat then the fuel tank this will expose the carburetor then its simply a matter of disconecting fuel line and unscrewing attachement screws. why do you need to do this? I would be very careful doing this as any dirt or dust or grime getting in can have huge impact

According to NGK sparkplugs at www.ngksparkplugs.com .

You Suzuki uses an NGK # DPR9EA-9 standard plug or a
DPR9EIX-9 Iridium plug. They both gap at .035".

Hope this helps.
