CB77 305 Super Hawk project

Hi all
Just inherited a little CB77
Plan is while restoring the CB400F Hailwood replica will be fullly restoring this little CB77 with my son in parallel.
First job for us tonight was to have a peek inside the tank as bike has sat for +10 years.
Not so good as stunk of stale fuel and red rust.
We are going to see if it’s superficial but if it is beyond repair luckily we found a spare tank tucked away with stacks of other CB77 spares in the back of my late dad’s garage.
Bike has good compression, so next steps is a full carb strip and rebuild then after a few checks together we will see if the old girl will fire up with fresh fuel via a remote tank and rebuilt carbs.
In all it’s a nice project as bike is fitted with genuine Honda clip on bars and rearsets and a nice father and son bonding activity.
Will update with posts as we progress with the restoration.
Best wishes Al.

Iirc the 305 has a 180 Deg crank, as a result two firing strokes are closer together so it never sounds as if it's revving as fast as it actually is.

Great bike, I had a 1964 CB 72 250 back in the day, (the CB77 is same bike bored to 305cc), I bought it around 1966 from Ben Lloyd’s in Crosby Liverpool where I am from. I was in the Royal Navy and used it as weekend transport between Portsmouth and home when I wasn’t at sea, it never let me down or missed a beat, I loved that bike. I replaced it with a 1966 Triumph Bonneville about 3 years later because I wanted something faster, it was fast but only when it was running which wasn’t very often, learned my lesson and stuck with Japanese bikes after that.
Good luck with the recommission and enjoy the bike.

Yes one thing that amazed me is it’s got 12v electrics and an electric starter on a bike that is 60 years old
No wonder the Japs cornered the bike market
