Model Identification<\/p>\n

Year: 1978
\nMake: Kawasaki
\nModel: B3
\nVIN: KZ750B-25701 <-> 033033
\nEngine: KZ750BE025701 <-> 033074
\nColors: Luminous Dark Green, Luminous Dark Red<\/p>\n

Characteristics that distinguish the ’78 model years from the ’77:\u00a0 Color, pinstripe layout\/design (4 pinstripes; 3 green and one gold, merging at the top rear of tank, hidden behind seat front), front brake caliper re-located from the front of the fork leg to behind, new angular front master cylinder, modern stator\/generator type (3-phase dynamo changed to single-phase in ’78), needle bearings in swingarm (instead of bushings), combination regulator\/rectifier (changed from previously separate units), slight design tweaks in the output shaft assembly, recommended fork oil level, and there is some uncertainty about the recommended spark plug (B6ES\/B8ES) between model years as dictated in the Kawasaki Service Manual.<\/p>\n

Other model characteristics can be found in the Kawasaki Service Manual.<\/p>\n

Here are some pictures to illustrate some of the important noteworthy model identifiers…<\/p>\n

I believe this pic below was originally in a magazine review (not sure which):<\/p>\n

\"1978<\/a>

This is a near-new specimen that shows the green color, the new '78 front master cylinder, the U.S. seat, U.S. rear fender, and U.S. turn signal position<\/p><\/div>\n

\"1978<\/a>

This pic shows how the '78 tank pinstripes disappear behind the front of the seat; of course the bike has a removed rear fender and replacement exhaust, but you also clearly see the U.S. - style seat, handlebars, and rear turn-signal placement <\/p><\/div>\n

I believe this pic below comes from Kawasaki, perhaps from a manual or bulletin:<\/p>\n

\"1978<\/a>

This pic shows the Euro-style seat strap, longer rear fender\/guard, lower handlebars, and rear-most turn signal position; as well as a glimpse at the rear-mounted front caliper<\/p><\/div>\n
