Hi, can anyone tell me what thread size the 3 screws are that go through the bucket and into the threaded tabs in the chrome rim? I don’t see thread details in the parts book. The diameter seems to be between m4 and m5. Many thanks.

They are a standard metric thread as I used some small Allen Key headed ones on my 500 that I had in a box of mixed metric ones - I suspect they are M5 but not 100% sure. I assume you mean the three that secure the headlamp rim & internals to the bowl.
Update parts book shows them as M5 x 16 mm this is confirmed in the middle section of the part number as well as the downloadable parts book p/n 93500-0516-0B the little spacers are not cheap..

Pretty sure they are M5.
Only time I’ve come across M4.5 threads was for the vesa mount on my old Samsung TV.
My Lambretta has some M7 bolts if I remember correctly.

Nurse Julie sells them

Thanks guys. Must be m5. I’ll get some m5s. Mike

I hadn’t thought about the spacers Ted; well pointed out. I guess the plastic bucket will crack without these. I’ll have a root around in the removed screws bag and see if I have them, I don’t recall seeing these when stripping down unfortunately.

The spacers are quite expensive so I bought m5 aluminium bushes from ebay ant ised a stainless washer to make up the tophat shape
