Reply To: Testing without tank – GT650R 2009 EFi
Does the fuel pump get a little louder as you rev up ? And can you ride it down the street and back when putting the bike under some kind of load.
And incase i forgot if you mentioned it or not, have you replaced the injectors and ignition coils too?
This week i was dealing with a customer GV250 EFi , the front was not firing and the ISCV worked extra hard to keep revs around 15000 which was funny to see but goes to show the ECU couldn’t even sense the coils were dead.
Now the ignition coil actually showed good primary and secondary readings …. = This is the dead coil. ? = I put it on the rear , the the back cylinder stopped firing.
So i was stumped, I concluded the coil had an internal fault despite readings being OK.
Here is funny part , the GOOD coil showed ZERO readings on the HT coil but it was firing up like a happy bunny on both cylinders , despite the manual saying if you get “zero readings” for primary and secondary = replace the coil! It was a day of cursing , i knew both injectors were working as the GV250 only has 900 miles! yes 900 miles 2016 model but it was left outside to rot! , so looks terrible but the engine miraculously still works , so i can finish recommissioning the bike.
I though i could say all this to have another crack at the injectors and ignition coils again.
