Topic: 1974 CB 550Four

Hello everyone,

I recently installed Keihin CR26 carbs on my 1974 CB 550 Four and am having trouble tuning.

Previous settings:

A/F Mix 1 turn out
105 Main
60 Pilot
P151 Needle/2nd click from the top

Was running okay, but sluggish and difficult at 3000-4000 rpm

Current settings:

A/F Mix 2 turns out
105 Main
60 Pilot
P151 Needle/3rd click from the top

The engine is responding to the throttle, but only slowly from the bottom.

Where to now, anyone?

Here is one example of CR26 tuning:
