FZR 400/600 HYBRID PROBS

[EZMOTO]

Hi, got a really annoying prob with my hybrid

i have just built up my 3en2 with the 3he engine running stock400 loom and 400 ecu and 400 exup exhaust
got the bike running sweet low down, idles nice and pulls right upto where power kicks in then it really plays up above 8k and wont rev past it
i tried the 600 coils and its better but still the same

bike revs up on the stand fine and sounds nice and clean, but when ridden really plays up

i'm running 130 mains with stock 400 airbox and filter removed

i am correct to say the bike should run fine with 400 ecu and exup still fitted? or do i need the 600 ecu and pipe?

in this case the EXUP is what is holding you back. The 3he is probably a non exup motor so running it with an exup setup is probably choking it. You may need to run a non exup ecu along with a non exup exhaust (or you can just set yours so it open all the time).

thanks for that, now the bike not only sounds different it goes like stink! cheers

had to cut top of snorkel off on the 400 airbox to get the best flow, but this bike fuels great all the way up using 130 mains, very very happy with this conversion
