The 99 cbrs have a zenner diode in the ignition switch that runs to the pink wire, which reduces the power from 12v to 9v(the amount needed for the fuel pump to run,) it's a safety thing Honda did so people couldn't just hot wire it.if that is broken, it won't start.

SOURCE: Honda CBR 900rr 95 Will not start

Check fuel pump is working(remove seat and tank)Although your bike has carbs,they are fed by a fuel pump(under seat and tank)
if there is no fuel getting pumped when you are cranking over,replace fuel pump relay(cheapest option)If still no joy your fuel pump is u/s.although hondas have a seperate small vacume type hose running off the back of the pump,any pump off a kawasaki zx7/zx9 will do the job(they are all made by the same firm)

SOURCE: rebuild the carb on a 98 honda cbr 900rr. Where

Dont rebuild unless absolutetly necessary or need to rejet. Try some Seafoam first, it might save you hundreds of dollars and a lot of frustration.
read directions on can or just try pouring 1/3 can into two gallons gas and really get on it ...it might clear up any hesitation or stalling if thats whats happening. I got mine at Autozone for $10.( And it fixed the problem after riding for about 15 miles.)

No spark out of my 1999 cbr 900rr

Could be the coil pack probably a weak stator,. Try a pickup coil for the stator if you can get your hands on it way cheaper then replacing whole unit. Good luck.

Coils were removed on a 1995 CBR 900RR I need to know on what cylinder from left to right, the firing order and what wire form the 2 coils goes were? same with the 2 wires that connect to the coil.
