CB400F An easy steal....BEWARE
« on: April 26, 2014, 08:27:51 AM »
OK i went to start my CB400f ready to go to work and nothing!! :(  No ignition switch light no anything, checked the fuse box there all good so not a clue and running out of time as i need to get to work,  >:(  so i got another bike out as i have four and went to work. So on my day off i managed to trace the problem to the ignition switch which has an electrical connector at the underside of the switch this can be disconnected and with a small peace of cable one connected to live and the other to the switch cable you can by pass the ignition switch press the starter button and bingo the bike will start. Now that's great if your ignition switch packs up on you and your in the middle of nowhere you can get yourself home. However a thief  can also easily steal your bike as well. >:( >:( >:(  Any way i thought this would be of help as i only just found this out myself and will be fitting an immobiliser...not sure if this applies to other SOHCs.

Yeah they are pretty easy to steal. Best easy thing to do us to make the switch harder to access

Or... bridge the light fuse to the main fuse and switch on your lights. If someone wants it they will get it. Best lock it to an immovable object.

I think most 60's and 70's Honda's are like this. You have to remember its easy to steal for people like us that know the wiring. I think technically there are 4 wires that go to the switch so that might trip up an average thief.  With my 71 450 I look towards other deterrents such as:

- Using the steering lock
- Pad lock around or though chain, or through sprocket holes and around chain
- Rotor lock (only works if you have drilled rotors)
- Chain around wheel and swing arm

Yeah, I believe your bike uses the same igntion switch as my 750F which means it has a steering lock. Use it and they can only ride around in circles once they jump the switch.

There is no real way to prevent it from being stolen if someone wants it bad enough. Pick it up and throw it in a truck or trailer.

I was just gonna say what Jerry did, they will just pick it up. Two guys are gone in seconds with a bike. Youtube has tons of clips, guys throw them in a minivan sideways

I'm with Jerry, they make steering locks for a reason. Years ago I found a way to turn on 750's way easier in less than 10 seconds  than what we are discussing here, but I won't say on an open forum. As added protection against any non starting feature I run a GPS tracker hidden on the bike. I use to run an alarm that didn't go off on the bike for 3 minutes but notified me immediately. That gave me 3 minutes to get to the bike and confront them with my 9mm. I don't like alarms that go off right away. They scare the thief off to be able to commit his crime on you or someone else later. I want to catch them red handed and put them in jail. >:(

I posted this on the other link below but my GS750 was stolen from my apartment back in 1980:
 I was living in Colton, Ca. I had a 1978 Suzuki GS750E. One night my roommate wakes me at around 1:30am and says there are cops out side shining flashlights on my bike in the parking lot. I park it with about 6 other bikes from the apartment complex. A few minutes later I get a knock on the door and I answer it to find 2 officers asking to speak to me. They ask me if I own a GS750. I tell them yes I do. They ask if I know where it is. I say yes it's right out in the parking lot. They say no it isn't we just recovered it about 20 miles away. Would you like to go and recover it or have it impounded and pick it up later. Knowing it would cost me, as a victim, money to get it out of impound I said I would go then and recover it from the scene. When I got there I asked what the story was and they said an officer was parked on the side of the road talking with some woman and 3 ni**ers (not my words) road by on it and the cops gave chase for having 3 people on it, at 1am that seemed suspicious to them. The riders ran down a deadened road that had a barricade of 3' tall posts separated by 3' and rode through the gap and dumped the bike in the dirt field and ran off. I jokingly asked it they had shot any of them. His reply was "I couldn't get a good shot, so no, he hadn't shot any of them. The bike had a small ding in the top of the tank where one of them was riding, a scratch in the side of the tank from when they dumped it and a screwdriver ignition switch, but I was glad to have recovered my bike so quickly.
I was surprised that they found me so quickly and came to me after finding a stolen motorcycle. I would have thought it would have been days before they notified me and that I would have notified them it was stolen before they got to me.

Even easier, put the lining out of a cigarette packet over the fuse box, instant ignition, it will bypass the charging system but even with lights the bike can be ridden a long way at night, in daylight it can be ridden for hours......  These old bikes need top be chained up or have alarms, they can be stolen in under 60 seconds very easily....

Steering locks are good guys but they can be broken pretty easily. Multiple locks and an alarm will make most a@#holes go down the street and take some punk kids new gsxr. I'm fine with that.

A friend showed me how to hotwire a CB750 back in the 1970's, it was so easy it was scary! ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

I discovered the same thing on my 350F.  I too suspected the switch so I bypassed it with a small piece of wire.  Lights came on and it fired right up.  I ordered a new ignition switch and matching locks for the seat and steering lock so I'll have a single key.  Pretty scary how easy it was.

Yes the steering lock is nice. I've also found that a lot of times you can lock a "Gun trigger lock" in a couple of places. 1 place being on a rotor that's been drilled, stops the wheel from being turned passed it :) ! Also a "small" lock placed through a link in the chain, yes it's small but once you lock it on role the bike a little so it hides under your sprocket cover. Not only will it not roll far it's also hard to see if they don't look a lot to find out why the bikes not rolling, LOL. Just another thought.   ..cougar...

A lot of disc locks now come with a lanyard that you can attach to a brake or clutch lever, because lots of owners forget that they've attached them, and go to ride off, with disastrous results............. ;D
