CB350F Rusteration

[mattsz]

Oh dear, that black stripe!  Well done on its removal...

No bench for me, the bike is still in one piece!  I do have lots of rags, though, so I'll just start at the top and work my way down...

[Moorey]

This mornings bit . Got the leaky float bowl off and the seal has broken, stuff just doesn't last anymore. Waiting foe new seals now.

Time to start on the back end, out with the wheel, swingarm and off with the mudguard, started with a bit of  a clean down with a petrol, diesel mix which leaves a bit of a oily residue.

Hopefully I will never need to refer to these.

Now off to exercise my hip by walking to the pub.

The domestic steam cleaning machines with single nozzle do a reasonably good job of getting oil based grime out of nooks and crannies. 

Or wall paper stripper/steam thing.  Always nervous about sloshing flammable stuff around inside buildings. 

Just get a drip tray underneath to let it flush down.

[Moorey]

The drive chain was washed down and left to soak overnight in chainsaw chain oil I believe this could well be the original chain, now hanging up to drip dry. Is there any way of telling.  Removed the swingarm spindle and bush it doesn't look like it has ever had a grease gun on it, but both are in very good condition a bit of a confirmation the indicated mileage is correct.

Attacked a couple of dings in the rear mudguard and they are far less noticeable now.

Nice work.  Do you use a car panel dolly on the mudguard dents?

[Moorey]

No just a pad of cloths on the bench to beat it on and used the rounded end of a old ratchet as a hammer. It doesn't need much its only thin. Gentle as you go.

You are cleaning away all the patina  , i don't think my 350f has ever been cleaned thoroughly in it's 47 years, though i do wipe down the bright work a couple of times a year, i must get round to it this spring .

[Moorey]

One mans patina is another mans muck.  , What about all that patina you have wiped away on the brightwork    Don't worry it will get mucky again as it will be my daily rider for a good while. I just want it to look like a old bike that's had a bit of love shown.   

[Moorey]

Well the smoke got the better of me and I removed the exhausts. Number 3 is the smoker and I am hoping it is just the stem seal that's knackered. Whats my chances of it just been the valve stem seal. Am I right in thinking to change the lower o ring the valve guide has to come out. Iv'e opened it up and it looks great inside, very clean a bit more of a indicator the 4000mls is genuine. I am going to order just one new valve seal to see if it cures it. I am doing it without removing the head. More as a exercise to see if I can. If it doesn't work and cure it I will just have to delve in a bit deeper.
The last pic is the seal and valve springs removed with the engine still in the bike with the head and carbs still on.
I will have to give some thought to putting it back together, but I have until the new seal comes.

looks nice and clean inside that rocker cover... 

[Moorey]

That's just how it came off. 

[Bryanj]

In too many years to think about i never changed a valve guide O ring except when replacing guides.

[Moorey]

Good to know Bryan.

What are the five 'c's on the crankcase for?
