Design Disadvantages of the CB1100

[Deanohh_imp]

From the Factory Service manual...

Intake timing for cylinders 1 and 2:
opens at 5 degrees ATDC, closes 28 degrees ABDC

Intake timing for cylinders 3 and 4:
opens at 5 degrees ATDC, closes 38 degrees ABDC

Exhaust timing for cylinders 1,2,3 and 4:
opens 42 degrees BBDC, closes 10 degrees BTDC

Maybe this is done to broaden the powerband of the engine as opposed to doing so for nostalgic reasons? At any rate, I'll take my chances, choosing to side with Honda's engineering team.

From a previous post:
this is a misprint in the shop manual, happens all the time with a non procedure specs.if this was a service check procedure red flags would have flown very early from feedback from service engineering and field service techs.i'm sure it will be corrected by next shop manual printing if Honda knows about it.
correct spec should read-
intake timing for cyl #1 and#4 opens at 5 degrees atdc, closes 28 degrees abdc
intake timing for cylinders #2 and #3 opens 5 degrees atdc, closed 38 degrees abdc
