CB350 K4 Side Reflector - Thread size ?

[Phil-UK]

I have a CB350 K4 brought into the UK from the USA and missing its front side reflectors ( that seem to screw into the fork shrouds ).
As these aren't a requirement here I was thinking of mounting a pair of LED daytime running lights but the threads in the fork shrouds don't seem to be the M6x 1.0 that I expected.
If anyone has one of the original reflectors could they measure the thread size please ?

thanks

Is the thread larger or smaller than a 6mm?. ..........lm

Hi LM

I tried a 5mm bolt and that is too small but a 6mm x 1.0 won't start: looking at it with a torch the thread pitch looks bigger than 1.0mm but I can't get a thread gauge in there.

M6x1.25?. ..............lm

Get a M8x1.25 bolt and grind the end to leave a small length of triangular of thread, that will fit in and use that as a thread gauge.
Hope this makes sense I'm not very good at explaining things.

M8 in a possible M6 hole?. ...................lm

Let's not make this more complicated than it is. Those are standard M6x1 threads full of threadlocker so the reflectors don't back out. They're $27.45 each new from Honda!
