98 Speedster Carbs

[KYmayfield]

Gonna rebuild my carbs on my 98 Speedste,r are the dual carb set ups BN-38I (SB), BN-40I (SB), BN-46I (SB). I'm confused as to how you actually tell the difference between them. I've attached pics for reference

You really don't need to know the difference but.... Only the 951/947 uses the 46i so everything else is the 38 & 40 and are exactly the same.
Yours are BN-40 with accelerator pump.
