Topic: newbie trying to get a cb350f road ready

[Captainmonkey]

I actually have two but I'm trying to get one running and driving.  I intend to get them both going eventually but one has a few pistons fused to the cylinders.  Anyhow I was just wondering if anyone might have any general suggestions, were to find parts, common problems etc.  I'm fairly mechanically inclined but no mechanic, that and I have never done a project like this before so I'm sure all kind of surprises are waiting for me.  Anyhow any input would be appreciated.  parts sourcing is my main concern right now.

here is what i have

73 cb350f needs some love, mostly electrical, fuel tank is a rust bucket and the carbs were vary nasty.  They are now striped and waiting on rebuild.  This one has some general parts missing, chopped up wires and what not.  It apparently has a cb750 front break, Im wondering if i need a 750 master cylinder.  the transmission shifts and the motor turns over just fine.  9k miles

74 cb350f this one has a locked up motor.  I have been tearing it down while waiting on parts for the other one.  I did try for some time to break it loose kicking it but after bruising my foot I decided that the pistons had become one with the cylinders.  I have the head of and its clear that at least one cylinder is utterly ruined.  I have never dealt with this stuff so I don't know how much is to much to fix.  Iv seen up to 1mm over pistons so I imagine  they could be bored out.  Anyhow this one is will likely be used for parts and be a back burner project.  3k miles

Thanks for any input

Tip some light engine oil into the engine that is locked up and just leave it to soak, there are more expensive fluids that others might suggest to unlock it too.
Parts come along on Ebay and through the classifieds on this site too, many forum members swap parts if they are close enough.
Ask, we love to help and we have some hard core CB350f members who just dote over these pocket rockets.

I have tried many different oils and soaked it for days, nearly a week.  The far right cylinder, I'm guessing that's number 4 is a rust pit  do you think there is any hope at a civilized approach?  I wish I had a pic of it.  Its pretty bad.  I was thinking of taking the jugs off via removing the rods from the crank so I could beat it mercilessly with a large blunt object. but I just read another post that sounds like the rods wont fit out through the top.

For locked engines, I've seena lot of guys suggest rocking it back and forth while in gear.  Perhaps use the special nut under the points cover to try to rotate the engine?  I'd use banging as a last resort...
