82 Katana 1100 - no keys

[Malone]

The project Katana I’m pulling to bits hasn’t got any keys at the moment, they’re in the process of being ‘found’. That’s not a problem as I have removed the seat and fuel tank from underneath. What I’d like to do if possible is see if I can get it to run in the absence of the keys.

unplugging the loom off the rear of the ignition switch there is a 4 terminal plug with 5 wires. Red. Orange. Brown. A doubled green

Red is power, and if it is connected to the orange then I get life on the dash. What are the others and can I use them to power the starter button?

No need to pull any wiring, or remove seat or tank. The 1100 (and 750) Katana are so stupidly easy to "hotwire" because of the exposed fuse box I'm a bit hesitant to mention it openly on here.. 

With connecting the red to the orange the starter button will have power. Unless you flipped the kill switch that is.

First get yourself a wiring schematic though.. Pulling any wires before actually knowing what you're doing is a no no.

Thanks, the whole bike is being pulled apart regardless. Connecting red to orange didn’t energise the starter button so there maybe an issue elsewhere.

Most older Suzukis for the UK market have a 4 wire ignition switch, that when on creates two independent circuits by linking orange-red and brown-grey. Hotwiring via access to the 4 wire connector for the ignition switch therefore isn't exactly rocket surgey As Arnout states, look at the correct wiring diagram for your bike and it will be clear how you can start the bike without using the ignition switch.

Thanks for the replies. My hearing is shite and the solenoid was clicking but no response from the starter motor. That can wait for rebuild time as I’ve pulled it all apart today.

It is clean, but up close it’s not that nice.

bought a bike with no keys ..took the ignition barrell off and locksmith at shopping center said ...oh its a Gurls blouse is it ,,,with no markings on it at all     !!!  ...1 day later and A$70 for two keys

I sent the ignition switch off and received it back in 2 days with 2 keys for £36. I was rather pleased with the turnaround and very acceptable price.

My EFE has a key number stamped on the ignition switch and on the bottom of the fuel cap. Worth looking on the helmet lock as well. Good locksmiths can cut a key from the number.
