Sort of wondered the same myself the other day. Except I been thinging of 750 versus 350. I assume the ratio is the same on the speedo. Anyone?

Not sure about speedo as the 400 uses an 18 inch front wheel and it could be either the drive gearbox or the head that is different. Dont know if 350 has an 18 or 19 front

The CB350F has an 18" front wheel & I've swapped both wheels from a 400F.  They seem to be identical as well as the brakes.  The 350F has greenish dials on the instruments & the 400F bluish but they interchange & work the same.  An additional tip:  If the instruments are sluggish or jerky & the cable is good & lubricated, turn the units up-side down & put 2 drops of light oil in the dirve adaptor at the input spindle.  Don't use too much.
