New (to me!) '77 CB400F - US model

The only obvious sign of low compression would be a lack of power and lower top speed.
From your description it seems to be running ok.

Hi guys - it's been awhile!
I've got the bike out of storage and back on the road... it's where I left it last autumn... starts well, idles well, stumbles mightily when pulling away from a standstill unless I rev it up to 3k-5k rpm as I slowly ease out the clutch... once underway it pulls well through all the gears and normal rev range. I'm actually quite happy with how it runs... except for that stumbling.
When I cleaned and bench-synched the carbs, I set the pilot screws to two turns out which seems to work well for the most part, other than the above - I followed some advice here and tried screwing the screws in 1/4 turn... which didn't seem to make a difference. Any other thoughts?
