*EARLY LOWER GASKET SET "B" SET S90 CL90<p>ENGINE #'S (S90'S_424487_to_527510) AND (CL90'S_to:_296867) 1/18M (332Z)

=========================================================

FOR THE S90 MODELS THIS IS WHAT I HAVE FOUND:

1. HONDA CHANGED THE MAIN CASE HALF'S AT LEAST 3 TIMES FRAME # 000001 to: 441567 THEN to: 575923 THEN to: 839857 THEN HIGHER

2. HONDA CHANGED THE CLUTCH COVER/RIGHT SIDE CASE AT LEAST 2 TIMES FRAME # 000001 to: 527510 THEN to: 674102 THEN HIGHER

3. HONDA CHANGED THE LEFT CASE/ALT COVER CASE AT LEAST 3 TIMES FRAME # 000001 to: 135974 THEN to: 527510 THEN to: 645880A THEN HIGHER

SO THE BOTTOM LINE IS THIS "B" KIT IS ONLY CORRECT FOR S90'S WITH FRAME NUMBERS AS FOLLOWS (S90'S_Engine_SN_424487_to_527510)

=========================================================

FOR THE CL90 THIS IS WHAT I HAVE FOUND

THE CENTER CASES WERE CHANGED ONCE FRAME # 000001 to: 296867 THEN HIGHER

SO THE CL90'S WITH FRAME NUMBER LOWER THAN 296867 NEED THE CONVEX CASE GASKET SOLD IN THIS KIT
