I looked for the old thread of mine about fuel pump fail ,could not find it ,
so quick up-date , new walbro pump installed and a fuel filter sytec under the tank ,it is flow rated and seems to be ok , but dyno man said i have big issues with fuel pressure ? It still pulled 175 bhp 92 lbs-ft but down on last years same dyno numbers 5 bhp and 6 lbs-ft of torque ,down. i have since noticed that my fuel return pipe was getting squashed slightly when tank goes back down ,which i think may have been the problem ?
Anyway the bike runs fucking real bad ,i only just managed to get it home last week ,throttle was very on/off ,you had to feather the throttle to just keep it rolling !!
No FI light ,it starts but as soon as you touch the throttle it revs and then cuts out ! could it be the pressure sensor ?
I have re-connected the original ecu (un-plugged PC5 ) no difference ?
Getting pissed off now , i have 2 new tyers to destroy and winter is here
over £100 for a new pressure sensor !!
