Yesterday was tune up day for my '78K/F, and continued work on the '79 CB750 DOHC.
The wife was working a 14hr shift and the kids were playing in the 'hood, so I pulled both out of the garage and got after it.
The '79 needed idle circuit plug chops, so i got it running and under a fan. Vacuum sync'd done too. Making small adjustments in these VB carbs to richen the idle circuit. Its got a K/Q seat w a sissy bar on it. Kids sure love rides.
Valves, cam chain done on the '78.
Swapped out 120 mains for 115's (dyno discussions w/Brewsky..and duanob for mentioning my rich-looking exh.)
Cleaned points. Timing/Advance done. Installed replacement HM ignition unit
(Last one had a bad board per HM. He quickly replaced it..no questions)
Oiled and wiped down the chain.
