I' m from Portugal, and I had try this mod on my hyo gt250 carby model from 09 but didn't work for me.
Portugal Delivered 2009 Hyosung GT250, Carby configuration.
M815 CDI Unit (From Factory) – Imprinted 32900 (on top of CDI Unit).
Instead of green wire, I have a green/white wire (see photos).
So, as you can see, first time I'd unplug the brown conector. I didn't know if the flatspot comes out, because with this configuration i just run a few seconds. I did notice that the fuel pump didn't work
(no tack, tack, tack... sound at all!).
I had try a second time with blue wire connected, green/white wire disconnected. Fuel pump didn't work again. I have to quit with this MOD.
Any ideas to improve this mod? Thanks in advance.
(sorry for my english, but is not my mother tongue).
