It started last october right before i put it away for the winter. My bike struggled to get past 120 mph....So i was thinking it was my clutch. This week I changed my clutch and threw in new plugs. this morning i took a ride and same thing happen. So i threw in the clutch lever a revved it ..the Rpm's started breaking up around 6500 all the way up to 9000 rpm. The only thing I threw on it for mods are 2 yoshi slip ons and the marble mod . I have 11,700 miles on the bike. Bad fuel pump? I am not sure on that because i can hit the limiter when I rev the motor in nuetral after the break up point. It's a 04 so i cant change the fuel filter.( in the pump) Should I try a fuel injector cleaner,dry gas or a gallon of race fuel to try to clean the fuel lines?
Rpm's break up
- Thread starter riironman
- Start date
+1Try some Chevron Teckron - Good Stuff
That's the only gas my busa has ever seen!
ok.. I tried the sea foam...rode for a few hours and same problem. i retightened the chain and took it for blast i cant get the rpm's past 7000 on a full throttle trying to get past 120mph. If it does go past 7000 rpm its skipping and choppy and jerky...and it doesnt matter what gear its in. Could it be the Fuel pump? I am about to bring it the stealership. Its a sad sad day that I am getting beat by a 2002 zx9 on the highway.:angry:
It does sounds like low fuel pressure. 11000 miles clogged fuel flter?! don`t think so.. Bad fuel pump? could be..
Check also your air filter and ram tubes, you never know what could it be inside.. Air starvation as bad as fuel starvation..

capacitor? What capactor has to do with your bike revving ok without load? (in neutral) and not under load?
Same with coils.... I have `em as well BTW
Gear position sensor could be if it stuck in 6 gear position.
Or if you have TRE. Nobody knows what it does anyway

I assume that your FI lights is not showing anything, right?
Well, then fuel pump is most likely your problem.
