Since my tank is off it made my airbox easily accessible, so.
I've got 3 roll pins and 1 bit of brass rod @ 1/8" x 1 1/4" which drops out with the greatest of ease. This must be the non-standard one?
The roll pins measure 4.3mm at their fattest as they are not truly round, and 30mm long.
No idea if these are original fitment or not, but they fit well and do the job.

They weigh 2g each btw so good luck trying to save any weight!

Edit; Just had a look in my assorted pins tin and found 4 stainless roll pins that fit a treat but are not brown like the originals.
