Bolt Size BS34

[bpd106]

Got my carbs out to replace intake set up. I noticed that one of the float bowl screws on one of the BS34's is missing. Anyone know what size these are? I've replaced the ones on a Mikuni 42 before, but I can't remember what size they are, or if they're even the same.

Thanks,

98517-04016 SCREW. PAN HEAD m4x16 good idea to replace them with allen head screws

Thanks! I replaced the ones on my Mik 42 with the allen heads. That is a great idea.

The BS38s use M4s on their bowls but they're only 12mm long, not 16. The BS34s use an M5 x 16 w/lock washer.

I'm sure this info is out there, but I cant find it using the search...

Does anyone know off-hand the correct screws for BS34 tops? Somehow mine are missing one each! Would prefer to replace with allen head, but not too picky.

They are M5's. The length will depend on how many brackets they go through, if any. No bracket would take a 10mm long screw, one bracket would take a 12mm, two brackets a 14mm. These lengths are for use with a lock washer.
