This is a follow up question to What are the causes of fluctuating intake manifold vacuum
I have a 2005 Honda CBR600 F4i which suffers from occasional hesitation at low rpm when accelerating.
After a compression test on a hot engine I got the following results in psi before and after squirting some oil down each of the cylinders. The manual indicates that I should be seeing 178 psi.
Cylinder 1 2 3 4 Before 95 90 95 90 After 105 135 135 135
The spark plugs seem to indicate that the engine is running reasonably well, they are darkish grey. The engine doesn't blow smoke and always starts easily.
Given that I've already identified that the intake manifold vacuum fluctuates between 5 and 20 cm Hg at idle, what is your interpretation of the above figures and what work would you recommend getting done.
