RD400E/F needles

Can anyone tell me the the needle size fitted to an RD400E/F?

I assume they are different to earlier 400s as the emulsion tube has the shroud on it.

Thanks Steve,

I'll phone Allen's on Monday.

Got a set of 2R8 carbs I wanted to set up as an alternative for my YPVS.

Got the needle jets for an RD400E/F and wanted needles, but didn't know which ones.

Might bore them to 29mm as slides are 30mm, so not much to take out.
