Hi Marcel, The bike is GT250EFI, carb won’t be issue. I’ll keep you updated and upload pics about plugs when I install the coils. I’ll also try to see how the engine runs with 1 cylinder, what the difference is if only front or only rear works. Thanks

Ahhhhhhhh!!!!
Its an EFI – Damn it, I hope the coils don’t trip up the ECU, i may have given you ones that are a bit too powerful for the ECU! – It may get shell shocked lol.

But if you get the dealer codes activated on the bike by following the service manual in forum  (even 650 GT has same process to activate code numbers) , it should tell us if its nothing to do with the throttle parts  (injectors, sensors etc).   I do have some efi parts off my own donor 2009 EFI, if need be, i know they work.
