Reply To: Fuel tap for GT125 Comet
Vacuum should not be blanked , the tap will need it and the fuel pump is actually needed too. The 125cc uses a DF52 Mikuni Pump that was made for the Hyosung family , so the GV650 actually uses the same pump, it has a flow rate of about 80ltrs per hour, no way the 125cc will maximize the fuel pump , infact it is needed to help it sustain speeds at the top gear as it works on vacuum pulses from the inlets.
Check your inlet O-RINGS , usually we check the O-Rings under the inlets before replacing anything else.
China inlets = Chinesium , it won’t beat the OEM quality but it will get you on the road asap until we find the super rare originals!
Check your oil filler cap, sniff inside hard, if you smell fuel , it sounds like fuel tap is “wide open” after engine is switched off , would suggest future problems with piston rings or hydrolocking too – The tap may have a burst diaphragm
Just some of my thoughts , hope any of what i said made sense to you ?
