NEW 1967 CB77 OWNER

Post by zads » Fri May 16, 2014 9:42 am

Hello all,

I'm new to this forum and a new 1962 Honda CB77 owner. I was at my uncles and one of his neighbours was selling this bike he has had for over 20 years.

I've never attempted anything like this before, but I see this forum is the place to be to find out exactly what to do and how to do it.

The engine has spark and it turns over, but it is not getting fuel. I thought my first thing to tackle would be to get clean fuel to the engine. I will start by derusting the tank, I saw a thread about doing this using a trickle charger. No fuel is passing through the petcock, so I thought I'll buy new screens and rubber to rebuild it. Then attempt to rebuild the carbs.

Is this the right strategy? I want to restore this bike and drive it, so my first goal is to make it mechanically sound, then worry about the looks.

Very excited about this and can't wait to start.

Regards

May be a 1967 but not a 1962.
For sure you want it to run and show if it needs parts then consider the restore. . ..........lm

What LM said, definitely. It looks like it's all there, and it's in good shape.

Your fuel problem (and I'm not the expert) could be a plugged up petcock, dirty carburetors or all of the above. From what was visible, the fuel tank internals looked suspect, and there will likely be residue and dirt in the bottom. It will need cleaning for sure.

Read through this site, and then decide what you really want to do. I was one who was just going to "get her running" and ride mine, but I ended up doing a complete overhaul. I won't ride her very much, because she means way too much to me and I don't want anything happening to her. And she's gorgeous - as yours certainly has the potential to be!

Hi LM, thanks for the information on it possibly being a 1967 and not a 1962. The serial number on the frame is CB77-1056100 and the engine serial number is CB77E-1056172 does that help distinguish what year this bike is?

Thank you for the numbers.

I've starting using electrolysis to derust my tank and it has been working great. I've done it 3 times for about 3 hours at a time (I find my trickle charger kicks out after that much time).

I'll keep doing this until I stop getting rust, then I'll throw some nuts and bolts in the tank and shake it around to knock of whatever is left.

I've noticed underneath the black paint there is red, I'm guessing this was originally one of the metallic red Super Hawks that was made towards the end of production. You can see the red paint in some of the photos.

After pulling the hanger out. If you are using this method you have to sand the top coat off the hanger where the positive charge connects and the area that will be immersed in the tank.

I took apart the petcock let it sit in vinegar then cleaned it. The screen is broken and some rubber seals need replacing, I'll get a rebuild kit. The fuel line that goes from the petcock into the tank is cracked, where can you get a replacement?
