before you go buying a CDI, check and make sure you have power to the coils. there's a main line that runs in the harness to power the coils, then it splits to each coil. if you get a break or short in that wire, you gets no sparky sparky.

you should also get a pulse on the other side of the coil when you spin the motor over, but since i'm assuming it's not sparking AT ALL, it's more likely going to be the switched hot lead to the coil than the pulsed side.

might also look under the right (ignition) cover and make sure the pulse generators are ok. i've seen the bolts back out of them before.

i think i have a manual for the 900rr's on disk, i can get you electrical specs on stuff if you want to check out what you have before you go buying parts. cdi replacement is generally a last resort after EVERYTHING else is checked out.

and uh, i have to ask, did you check the fuses?
