Walbro pump all installed and fuel filter under tank (not in tank) .
took it to a well known zx12r chap ,he run it 1st and said it was well rich 150 bhp ish ?
he remapped it to 172 bhp 92 lbs-ft , he said leave it alone ,and all is well .
But i was not happy with it , at 5,000 - 6,000 rpm steady , you could feel it ,a on off throttle type thing , but only slight ,anyway it was already booked for a dyno ,so took there anyway , P.D.Q very good place to shop !
so the chap just done a power run , but he done quite a few full on max rev runs , and said i need to sort out my fuel pressure ? fit a AFPR .
he showed me all the numbers , and i had -60 ,he said you want those numbers right down ? i think i picked up on what he was showing me
I thought fitting a walbro 242 all new hoses and re-useable good quality filter outside the tank ,would of been a bit less hassle ?
So i am now looking at fitting a AFPR ,which again is not up my street ? may -be i am being a "rivett counting" type of bloke , all i want is for my 12 to make max power and run spot on , soon as !!
