I'm a Rookie, How do I Wheelie?

hey everyone, i been having a problem with my cbr1krr and any suggestion and tech helps will be gladly appreciated.

it started 3 nights ago. going 70 mph on the highway, suddenly hit a bump then goes the christmas lights(malfunction, HESD, FI lights) comes on all at once. i can tell that FI stops blowing gas for 1 or 2 seconds and at the same time the bike jerks off like it wanted to stall. then those lights go off and back to normal but hitting another bump makes it all happen again. today it has become real bad that i haven't even hit 30 mph or any bump then all 3 lights comes up and jerks the bike and it constantly comes up that i gave up riding and turn around after not even 1/4 mile away from my house.

guys, any feedback about this will be nice. i can't risk riding her anymore cos it's so scary when it jerks that i might crash and hurt myself.

but really, what does the hesd has to do with the fi?

i seriously need help about this. thanks y'll.

Electrical problem... probably a bad connection or ground in the main harness at or near the ECU. Check your manual to find the ECU, unplug & replug them in to make sure they're seated right. Basic solution...

damn cbr's i love it but electrical problems on it are just inevitable man. i've heard those comments bout electric problems on it but i never believed it. i thought it was just how the rider rides it.

i checked the ecu. plugged it out and plugged it back in and i thought that was it(got me fooled) then problem persist once again.
