Bike Model = : Gt250r efi 2007
Hi i have a hyosung gt20r efi 2007
i tried i think almost everything but it wont start ! :/
so the problem
It cranks , have spark, fuel… but if it strats its just the front cilynder sometimes it reacts to gas then off… sometimes it wont even start with one cylinder just bang a big flame even backwards to the injectors … sometimes it does nothing lol
i changed the fuel pump , spark plugs, sensors, the injectors, ECU , timing is good , compression is good
little more info
like 1-2y before it runs good no problem the last owner put it down for 0.5-1year And the fuel pump gasket melts in to the fuel… time passed i went there to buy it but the fuel pump cloged up and dead… and here we are
