The lightning Project, 12…

I  have slightly neglected the A65L due to sorting out the Guzzi Eldo, but when time has allowed I have been picking off the jobs that need doing. The biggest holdup has been sorting a replacement set of forks, as when I bought the BSA it had the wrong year forks and front wheel fitted. But finding the correct forks proved to be a lot harder than I thought it would be, but with the help of one of the inmates on BritBike.com I was able to get a set that needed a full rebuild.

Back at the beginning of the year I found a complete front wheel at Shepton Mallet VMCC jumble, and then I grabbed some tyres at the following Kempton, I have since fitted the tyres and new tubes, but managed to pinch and hole the new tube on the front wheel.

A65L New Tyres

I also have the motor all bolted up and ready to go, just need to add fuel and oil, so when I finally get the front end all back in the frame, I can get the bike off the bench.

Now where was I?

With the head all bolted down, and the rockers installed, it was time for those new SRM tappet adjusters to be fitted…

Next on the list was cleaning and refitting the exhaust system…

So I am getting there slowly, I need to order a few small parts, rocker cover studs, headstock bearings, and I still need to find some forks, but so far so good.

My head having returned from SRM, was now ready to be fitted, and after a question asked in the competition section of BritBike forum, I equipped myself with some copper sealant, and a pair of small o-rings, so I was ready to go.

Barrel and gasket prepared and ready for the head to be fitted..

Coming together

And another unexpected bike joins the group.

The lightning seems to have taken up residence on the bench right now, the whole front end is out, the head is away at SRM having a full on valve job, I was hoping the head may have been completed this weekend but not so. As can happen sometimes, I managed to break a piston ring fitting the barrel, and the broken piece of course dropped into the crank cases, and could not be seen. But some fishing around with a telescopic magnet found it in the bottom of the cases. So after again fitting a spare ring to the piston, and some help from Paul, I managed to get the refinished barrels in place, bolted down.

Next it was time to fit my new SRM magnetic sump kit, after removing the old studs I offered up the new gauze filter, only to find that it did not fit! it seems that SRM sent me out a kit for a B50 or other single, as the hole in the gauze was too small (8.5mm instead of 11.5mm) to go over the scavenger pipe. Luckily my old filter gauze was in very good condition, so I decided to use that rather than wait for a replacement from SRM.

Then it was just a case of bolting it all up to the underside of the motor.

It won’t stay shiny for long.

Vincent Comet…

I had a call from a mate in the US, telling me to go look over a Vincent Comet with a view to buying it, well a long story short, I did, and so I ended up with a Comet. I never thought I would ever own a Vincent, so getting this has come as a real surprise to me.

Pulling it all apart, putting it all together.

I have now for the moment taken the motor as far apart as I intend to go for the time being. I have drained and flushed through the crank cases, and was pleased to find no metal in the drained oil after letting it stand in the tray for a week, and filtering it off over a strong magnet.

The cylinder head has gone off to SRM in Wales for full refurbishment, which includes lead free seats, new guides, valves, springs etc. This work wasn’t cheap by any means, but it should last me out, and make for a good top end. I am looking forward to getting the head back so I can button up the top end.

Last weekend I cleaned off all the old base gasket material, and fitted the new pistons, I also honed out and painted the barrels ready to be fitted. I would have fitted the barrels but the supplied base gasket in the kit I bought was for the 1/4″ stud version cases and not the 3/8″ as required on the later cases, so again I find myself waiting.

Next I turned my attention to the front end and dropped out both fork legs, water had got in through the torn gaiters, and was evident in both legs, water came out of the right hand side, but the left hand stanchion is at the moment seized solid. So I have left it soaking in some penetrating oil for the week, I shall see how it does this weekend.

It has been a wet day here in the UK, heavy rain on and off all day, so not too much done with the A65, but I did manage to hone out the bores on the barrels, and run the carbs through the ultrasonic tank. maybe if it is dry tomorrow I can get a bit more done.

Tank off, and deeper in to the mire we drift…

Original Lucas harness. This is a good sign to me, and I shall go through the connectors, and make sure the solder is good, and all the connections are cleaned and corrosion free before use, I may even put a new fuse board in the mix somewhere too.

With the rocker cover off you get to see the pushrods and rocker gear, everything looks pretty tidy in here..

Remember where all the shims and springs go..

Springs and things

You need to remove the exhaust rocker shaft to access the front head bolts, before removing the head. and the front top stud, so the head can clear the frame top tube. This is also a good time to remove the Amal carbs.
