We are in the process of correcting wrong information in the Shop Manual Honda CB500-550, where it mentions 49±1,5 mm on p.8. The Haynes manual (CB350-CB500) in Chapter 2. Fuelsystem however says: 40 mm ± 1,5 (§8), at least it does so in the Dutch edition. Now the info in the Honda Shop manual is clearly incorrect. It's either in that fig. 5 or that 49mm. But is Haynes right? Did Haynes knowingly correct the wrong info in the Honda manual or is that '40' a typo? Can any of you look up what the English edition says? Thanks a lot.
