Today I cleaned and measure the flow of my injectors (2008 1125R)

one of the injectors have 30% less flow than the other!!

OMG! it is possible to repair?

or I must buy new injectors?

Regards
Zecca

Sorry Zecca, got you and Andros mixed up...
Check your AFV numbers in Diagnostic Mode.
That should tell whether it's in the ECM or the injectors.
If you're sure it's the injectors -

Try running some fuel additive for injector cleaning thru a couple of tanks.
If that doesn't fix it, you most likely will need new injectors.

Boa sorte

the injectors were tested on bench!!

the injector that has less flow makes a different noise too!
Could I buy the injectors 09 without changing the mapping?

Yes you can, it's a fairly common fault now with the early 1125's, think I may gave been the first with this problem. The later 09 style injectors are working great for me now.

Take a read of my experience

How much do they flow? was going to flow test mine to see if they were suitable for some of the plans I have for the bike.You could save me a job.
