Reply To: GT650 EFI leaning out
Last update for this thread I think.
Yesterday I replaced the plugs checked the leads and coil packs.
The plugs were average so replaced with new NGK CR8E
Leads looked ok.
The coils and where they mounted to the frame were fairly rusty so I cleaned them all off and re-attached.
The bike now has no hesitation and appears to go through the rev range happily.
