Did not know Honda could do the keys with Vin#'s....This is actually a great suggestion and I will try this method first before I pull the tank off.

I just got her running....well aside from waiting for the new ignition switch and front fairing to come in...I really hate to tear her down again until I least ride her for a few hours. So far I've only gotten 3 hours total of riding time in before the ignition diode went out on me.

Once I get the new fairing and paint them like i want I will post pictures up.

Right now shes all naked with just the tank attached.

I'm having the same problems with my bike it's a 2001 cbr 600 I'm getting no spark and no fuel pump turning on dunno what to do but I've replaced every thing on the bike except the ecu are there a resistor that needs to be replaced

check voltage coming from pink wire located at the ignition switch...it should be 9v...if goes to 12v,replace the 3v zener diode soldered inside the ignition switch

it's on the switch where the pink wire is attached to it.

I got this 929 in a trade and I've never heard it run the wiring harness has been hacked so I took a wiring harness part checked it all got it all back together there's no key for the bike I pulled the ignition pulled the Tumblers I got it to where the ignition it turns by turns on no fuel pump still no injector fire I don't know what to do I'm at when Whit's End

where did did you get the zener diode at because I ordered two different ones from two different companies and neither one of them worked but when I connect a 9 volt battery I seem to get Spark but the zener diodes are ordered that says 9 volt diodes does not seem to work and I believe they only go one way you can't flip the dial to round it won't work it only goes One Direction. So I tried both directions you can use the voltmeter. Still do not get 9 volt as it says it would so where did you get yours if it . How much was it?

Is it not a 3v zener diode that is required to bring the voltage down from 12 to 9. Not a 9v zener diode which would bring the voltage down from 12 to 3?
