More Guzzi Ramblings…

Rally season is now well upon us, and I have already missed one rally this year, but the next one is one I will not miss, the Belgian John Bull rally, a great rally hosted by the Belgian BSA-OC, for British and classic bikes.

This year I intend, well hope to attend on my 73 Guzzi Eldorado, and I am frantically trying to get it ready for the end of the month. I still have a few bits to sort out over the Easter weekend, and then with a fair wind it should be done. We shall see.

Those of you who own, or have owned a loop frame Guzzi, will know what a pain it is to replace the carb to airbox rubber. And after trying unsuccessfully to get it into place time and again, I finally came up with a plan that worked. Actually it worked quite well too. The successful method was to use two hacksaw blades positioned so that the rubber could be slid into place, and held while the carb was put back on, then the blades are pulled carefully out, job done.

A couple of pictures from todays visit to my lockup, first up is the front wheel I picked up yesterday at Shepton jumble, as you can see the brake plate is nice, but the rim is shot, so I think I may well get a new rim fitted when I do the front end change.

And back at the last Kempton Jumble, I picked up a nice set of Craven Comet panniers, and an old rack that may well end up being fitted to the Lightning. or maybe they will go on my Guzzi, we shall see.

The next step is to remove the head, so we can check the condition of the combustion chamber, the valves, the bores, and of course the pistons. Somewhere in here is the reason for the low compression in the right hand cylinder, it is just a case of checking out the parts as you see them.

The valves seem fine, and have no leaking, so that really only leaves the piston or rings.

Valves

Now we get the heart of the matter, the first look at the bores, and piston crowns, there was a fair bit of carbon build up, which I have started to clean off the pistons. There is slight scoring in the bores showing signs of previous trouble, a minor nip up, or a ring broken in the past.

A65L barrels and pistons

The barrel just needs a light hone, and will be good to go, the piston crowns show +20 so there was a past problem hence the signs of previous scoring, and with the barrel removed we find the cause of low compression, the rings are all stuck solid in the right piston, nothing too major then.

Stuck rings = low compression

Right time to strip and clean all the parts, hone the barrels, new piston kits, valves, valve guides etc, and start building it back up.

People Are Strange…

People are strange when you’re a stranger
Faces look ugly when you’re alone
Women seem wicked when you’re unwanted
Streets are uneven when you’re down

When you’re strange
Faces come out of the rain
When you’re strange
No one remembers your name
When you’re strange
When you’re strange
When you’re strange (The Doors)

So said the Doors…. And in some cases it seems to be true, especially when you start looking at old bikes that have an unknown history, and just when you think you have seen it all, up pops something new that makes you chuckle to yourself, whilst at the same time makes you recoil in disbelief as you wonder what other little surprises await as you dig further into that “new” old bike!

Today I started pulling the top end apart to try to discover the cause of low compression on one cylinder, so the first thing that needs removing is the tank, which as had already been noted had the wrong fuel taps fitted….

Oddball fuel taps

but what I discovered here left me speechless, in an amused bewildered sort of way!

No it can’t be?

lightning001_002-copy

Yes it really is, a Coaxial cable joint?

Yes, that is an ariel coaxial cable joining piece!

Update…

I have been informed that this is not a CoAx fitting, but is in fact a type of fuel tap specific to the USA, with a ball valve that runs on the nylon liner, but I was also told the flow rate was pretty bad, so they were often replaced.

It was a good day walking around Kempton Jumble today, I managed to get a few things for the Lightning, so I can now start to get this thing headed back towards the road where it belongs.
The first things on my list were the handlebars, and the Lucas rear light, well as you can see I found some new Triumph western style bars, and I also found a genuine Lucas rear light unit. These two items alone have transformed the look of the bike.

Before…

I also have new gaiters to fit, new fuel taps, and fuel line. but first tomorrow I will be pulling the head to see what the top end looks like, due to the fact the bike has low compression on one side, maybe a stuck valve?

The label on headstock says it all… February 1970 A65L.

So that is where I have started, and now I start sorting parts, finding what’s good, and also what’s bad. And ordering new parts as I start to get the bike back on the road where it belongs….

As I intend to pull the top end, I have started getting a few parts for that area, de-coke gasket set was first, and while looking at the SRM site, I saw these nice tappet adjusters, which arrived today…

I have also ordered the new fork gaiters, and some stainless cable guides, but a list shall be made of required parts before the next Kempton jumble in a couple of weeks.

 

Netley Marsh Eurojumble…

One of my high spots of the motorcycle year is the Netley marsh Eurojumble, held down on the edge of the New Forest in Hampshire. There are always lots of visitors from across Europe and further afield, both buying public and sellers, so the event always has a good “buzz”

Nice old OEC

I managed to buy a few bits for my Moto Guzzi that I had on my list, which was worth the trip in itself. Roll on next year…
