hi im a new bike owner. im learning about my 94 cbr 900 rr. ive had all kinds of problems, but this time im blowing my main fuse about every thirty mins. i replaced my rectifier, stator and battery. i can ride about 30 mins or so then it kills the power and i replace my main 40 amp fuse and then ride for another 2 to 5 mins just able to make it home. any ideas of where to start? or what to look for?

 

Look at all the wiring to see if something is touching the frame. make sure the harness has not rubbed through and is shorting. try to determine when it happens were you turning, bumpy road hard accelleration etc.
