That's what I have on mine.  Works fine.  I don't think the speedo is accurate to begin with.  That's why most cops will give you 7-10 mph before they'll write you up.

Kenda's site list their tires, width x diameter:

K657 Challenger Sport Touring:
130/90H-15  :: 5.2 x 24.1
140/90H-15  :: 5.7 x 24.8
K671 Cruiser Sport:
130/90H-15  :: 5.3 x 24.0
K673 Kruz Cruiser Touring
140/90H-15  :: 5.7 x 24.88

For Comparison: (manufacturer's specs)
Metzeler ME880 Marathon:
140/80-15   ::  5.71 x 24.37
Dunlop D404
140/90-15  ::   5.85 x 24.73

The 140/90 Kenda's are nominally the same width as the 140/80 Metzeler and considerably narrower than the D404 that many have used with no problem.  Nearly a half inch taller (diameter - only a 1/4" less clearance) but if you rub you can just crank up the preload on the shocks or replace.

The 130/90's are slightly smaller, can carry the weight, and should be slightly more responsive in turns.

Using the Metzeler as base, speedometer error would be -2.09% to +1.52% -- about 1 mph at an indicated 60.
