Hello everyone , first of all sorry about my english (still learning . So ive got a cbr f4i 2001 with huge oil leak behind the coolant pump . I was told i should change an o- ring ? But i like to bu sure thats the problem ? (its really deppresing ) . And also i like o ask if anybody know if i can change front master cylinder from f4i for a plastic one ? Thank you guys . I like to put here the picture of the leak but idk how

 

you can attach the files from your computer for pictures.




yes, i'd be very surprised if it was anything other than the o-ring. AND its a cheap and easy place to start. that's what i would do. it should stop the leak.



i'm not sure what you mean by a plastic master cylinder. that wouldn't be good. brakes are a simple hydraulic system, and you can interchange any master cyclinder so long as it mounts to a 7/8in. clip-on. if you're talking about the reservoir, you can change that too with anything so long as it clears the fairings when you turn... i run the rear reservoir on my front brakes on my fighter.... no problems.
