1975 CB750 P2 Police Bike
JamesH:
So the bike is pretty much finished - just awaiting finalisation of the tank and side cover. I have the unenviable task of fitting the decals later this week before the tank is clear coated by the painter.
Anyway, airbox is now fitted, carbs synchronised and she runs really nicely.
Have finished the siren installation; the proof of concept 3D printed roller drive bracket was a great guide for my local welder who modified the 500/4 bracket to match my design.
Correct length clutch cable sourced and fitted.
Revised design for the 3D printed siren cable clip fitted - I’ll need to make a final design change to this but it’ll do the job for now.
I also managed to source a ‘low profile’ blue patrol light to match the red unit I had with the ‘clear’ lens. So I’ll fit these reflectors to the bike tomorrow at some point.
Also fitted and aligned the NOS seat and very please with how she’s looking. The paintwork will be the icing on the cake once ready.

Nearly there James, start up day very soon.
Please post a video of the completed bike if you can with the siren engaged and the lights flashing, it will be the icing on the cake for something so rare and I have never seen anything like this before.

I'm looking forward to hearing that siren.

That’s a very fascinating restoration, cracking job! Looking forward to hearing of its first “Patrolâ€

Amazing work - lovely.
‘Concerned’ 😂 at the RPM at 80mph of the siren drive cable. On the assumption of no spindle gearbox at the rear-wheel off-take, and using a wheel diameter of 56cm and the spindle dia @ 4cm….. I reckon the cable would be spinning at 17000RPM.
Imagine that coming loose flailing about your right knee and ankle …. or worse snaking towards the family jewels as you pursue Jonny Burglar 😱.
By contrast, at 80mph the speedo cable is spinning @ 3500RPM, and the Rev Counter cable abouts 2400RPM.
Maybe don’t try it James … certainly keep the cable well lubed!
Happy to stand corrected… I hope I’m wrong!
