CB650SC/New Owner Suggestions

Should replace

O-rings

Avoid fuel leakage:

• Carb "Tee" x2
• Carb bowl x1
• Carb flow tubes & vent "Tees" x8

Avoid Air leakage(leads to lean):

• Carb-head x8

Avoid low head/cam/tappet lubrication:

• Valve-train oil pipe x2 & x8

Avoid low oil pressure/dirty oil contamination?:

• Oil filter tube x4?

Carburetors

• Check and replace with same jets & emulsion tube or reuse (order individually by size, no kits)
• Reuse needle (do not trust "kits")

Hydraulic Tappets

• Follow manual for removal
• Use allen key (my recommendation), smooth bore side of 1/16 drill bit (Clymer manual), or special tool Honda 07973-ME9-0000 to bleed out oil
• again bleed upright under kerosene (mineral spirits or maybe even diesel fuel in a pinch?) to clean
• bleed out the solvent from the last step
• bleed under engine oil until primed (pushing on the taper without the "bleeder pin" should feel like it is basically completely solid
• keep upright and install with the tappet lower hole toward the (toward spark-plugs) squirter?
