Honda-SOHC

Looking at the 3 pictures above, I think my lock was like the first picture... thanks very much for the parts...

That would be really good if you could... Thanks v. much...
What I am trying to do (because they butchered the lock cylinder on seat lock & smashed the ignition lock ... how they managed to do that without smashing the idiot light cover - I don't know!), is to rebuild the seat lock with a new lock cylinder and replace the top (mechanical half) of the ignition switch. I have a set of SH locks coming in post, which I'm hoping I can get keys cut for from the key code on seat lock?? alternative is to strip down the lock barrels and match the lock wafers up ... we'll see... but any info/piccies up front for me to study would be really good!

I have disassembled the ignition lock on my 400 Four, as I wanted to keep the one key operation. When recommissioning my 400,  I found out that the switch part had melted. The mechanical lock part separates from the electronic switch by releasing the plastic tangs. I obviously just needed a new switch part, but be aware there are two types of switch part / barrel parts which are not interchangeable. I have a couple of s/h original parts and a barely used DSS one if they are the same type. Let me know if you want a couple of piccies, I can photograph at the W/E

Hmm ... looks like I've stirred up a hornet's nest!!!
Not exactly my intention ... what I was hoping to do was something positive, that is the challenge of sorting/repairing the bits to get my bike back to top condition ... along the way hopefully helping some others out who are looking for similar info. (e.g. vin plate replacement - as above...)
Oh... and in case it got lost in the above "discussion":

" ...Another thing I am having to do is replace ignition & seat locks. OK with seat lock, but was looking for help on disassembling an ignition lock in order to make both seat lock & ignition lock to work from same key. Any pointers would be greatly appreciated ...."

- any pearls of wisdom? I know you can get Chinese replacement locks, but I'm interested in rebuilding a set of original locks ... depending on how successful I am I may well get a pair of Chinese locks anyway (& then make them work with the same key...). I am quite used to rebuilding locks... so it's something I'm looking forward to getting on top of!

Possibly, but at least they are aware. Might be worth alarming the garage to make a repeat attempt harder, plus the insurers will view it favourably.

Actually Nottinghamshire police victim support dropped me off 2 vibration alarms to stick on inside of door - boy are they LOUD!!! Hopefully that will help. also cameras to an NVR.

This the link to the thread I found ... also some extra useful info. about what needs to be stamped. Stamping was included. Cost £25 for stamping & £16.95 for plate. There is a range of blanks to chose from. Pretty good quality ... the odd stamp pitching slightly out maybe but very good overall... Judge yourselves from photo ... I have intentionally blanked out the frame number ... also came with a pair of rivets ...

Having had my bike recovered by the police, I have decided not to make an insurance claim but have some bits to sort out. By the way thanks for the encouragement/support I've got from people on here ...
Now down to business ...
Vin plate removed - searched on here & found uk based place to supply a stamped plate which was good. What do you think of outcome?

Try www.vin-plate.co.uk they have Honda ones.

Spotted that on another thread & ordered ... even found the right info to get stamped on it... thanks for that!

The gauge bracket is fine but the top yoke I think was bent when they butchered the ignition lock... the gauges now interfere with end of brake master cylinder line. Thanks for the kind thoughts anyway...

I have a couple of the gauge mounting brackets. I know they are CB750 ones but which ones I know not!

If you post an image I can check. Must have taken some effort to bend those lugs.
