CB750 Police

[JohnT]

I can't see a neutral switch in the P schematics, am I missing something? There is something called a changing switch, so not sure what it is for.

Hi John,
don't forget mate that the CBX750P model was probably 84 onwards. I only included that as it might help with police lights, siren etc.
If you are checking your starter motor operation, I'd go with the CB750K chart.

Nearly done, ground up rebuild, everything cleaned or painted, had a lot of surface corrosion.
Question: what causes poor spark, bad earth? Won’t fire on recommended DR8ES-L, but will with colder DPR7EA-9?
Does this model have a park light, it has the bulb and wires, but can’t see in any schematic?

Looking Good John!
Really like those 4 in 4. I still haven't managed to find a set.
Not too sure about the bad earth, but one place I found I didn't have good continuity while assembling mine was where the negative battery terminal lead ends in an eyelet, RHS upper rear engine mounting bolt. Maybe worth checking?
Mine has the park light too.

Odd thing about the park light is, I can’t find any reference in the schematics, and can’t find any stray wires, other than police gear ones either.

Hey John,
I think mine was originally from South Australia too. And I think that it was South Australia police that had put those fairings on as all the CB750P bikes from SA have those fairings.
In regards to the box assemblies on the side, yours are exactly like mine. I found on CMS that they are from this model...

My guess is SA police either ordered them with those boxes from the start, or simply upgraded to newer ones whenever they swapped broken boxes. But while researching and looking for photos on the net I have seen our same side boxes on all CB750P models originating from SA.
I found this pic, this guy has actually got a collection of them! ..

Hugh,
Trying to get a gauge on where the market is at with these bikes, I am thinking of advertising mine now that it is back together, but need a range, any thoughts?
