Just to answer the question why during at cold temperatures only? Kasi compare to carb types adjust lng ng konti sa engine mismo with the basic tools ay solve na. Normally for EFI types it happens most of the time kasi of the set ECU program. kasi its auto set already base sa stock set up. I dont know lang check niyo sa suzuki service center kung handled ba nila yung ECU repair or most likely change ka itong part. FI´s must have the auto mix set to the motorcycle itself bro, yun naman ang advantage ng mga carb types.... ikaw mismo ang mag titimpla ng engine mo basi sa panahon na kailangan.
