Singles / A65 pistons
« on: 12 October, 2017, 12:04:15 »
Hi :)

I have seen listed some 7:1 pistons and as I need a set of pistons I am giving this some thought. Mainly because it should be easier to kick it over.(If I ever get to trying it again)

What were they in originally??

What sort of effect would they have. Radically underpowered or only a little????????

Twins / A65 Cylinder head
« on: 06 October, 2017, 10:22:05 »
Hi Julian 8)

At the risk of boring everyone else rigid I still don't know which cylinder head I've got. The casting no does not appear to be recognised by any of the "dealers". So what alterations were made and when. All I know is that at some stage the Valves were changed. That infers that the seats were also changed.

Do you reckon that I can check this out simply by measuring the seat diameter or what else might you suggest.

What were the valve changes and was the head casting actually changed in any way.

Your help and advice appreciated.

Twins / A65 Camshaft
« on: 30 September, 2017, 11:08:41 »

Good morning. I am rebuilding an A65 engine to Thunderbolt spec. I have a camshaft No 68-0473 which I am lead to believe is high lift???. Out of a Spitfire or something of that ilk.(According to Draganfly,-----I don't know) If I remember rightly the correct one is 67-356??

I know the dear old Thunderbolt with standard pistons etc doesn't need that amount of breath, so what will be the probable effect if I use it
I suspect very little but I would be interested in your thoughts.

Twins / A65 Cylinder Head
« on: 25 September, 2017, 15:16:55 »
Hi.

I have purchased an A65 Cylinder Head minus the inlet manifold and my thoughts are that the A50 and A65 are probably different

I am confused about this because although the A50 carb bores are different I cant find a definitive answer about the manifolds.
In one book they appear to be the same, another book says they are different and a further book doesn't even mention them.

So any light on this one would really be appreciated. I would also like to hear from any one who has one or has a cream crackered head they might part with

Twins / Oil Pumps
« on: 20 August, 2017, 09:41:08 »

Will the "drive end" of an A50/A65 fit and work with the "pump end" of the earlier A7/10 B31/32 etc. It would appear that they should go together OK but your advice would be very welcome.

Twins / A65 Pistons
« on: 17 August, 2017, 13:57:28 »
 :)

Greetings.

I have just bought a set of A65 barrells and pistons.

The pistons are Stamped on top  68-793 BSA.            46   6/66   L

They are also marked by the gudgeon pin hole  68-743.

I cant find anything that relates to these No's in any of my lists or on Draganfly. (In fact Draganfly says that 68-793 is a dowell)

So what have I got??? any help or advice greatly appreciated

The Star and Garter / Stuck valves/Stuck cylinder head
« on: 14 August, 2017, 12:32:09 »
 :)

Just thought I would waste every body's time, with a quick hint.

Freeing stuck valves and heads so you don't need a hammer.

Tools req:- Plug spanner and about 4' of about 5/16th diameter non hairy nylon cord.

Method:- remove plug/s, rock bike in gear until the piston/s are about halfway up on compression stroke, feed the cord into the bore (keep at least 1 foot in hand) now rock the bike forward and the bunch of rope will either A. push your valve back into place, or B. will push head off depending which you are trying to do. You will probably still have to locate your pushrod unless you are seriously lucky.

Does it work:-  Yep never failed for me and that includes extreme use on a Cessna aircraft engine and pushing the rusted head off an ancient Fordson Major tractor.

Singles / Sloper pistons

Some help please gents. I have been asked these questions and I'm completely out of my depth here.

Question 1. Does the Sloper and the Blue Star use the same pistons.

Question 2. Was the Sloper ever produced as a 550cc or indeed anything other the 500cc.

Thanks

Twins / A65 Crankshaft
« on: 02 August, 2017, 09:16:13 »
 :) :)
I have a barn find A65 that I think I shall rebuild.

Well what I actually have is a frame, swinging arm and bottom engine casings with only the gear cluster still in it (9bonus???).

My question is were the crankshafts standard and relatively interchangeable during the production of the marque. I can get a crank quite easily but don't want to end up with something that doesn't fit.

So as always your advice would be very much appreciated.

Oh almost forgot I've also got the rear brake rod (another bonus)

Singles / M20 girder forks
« on: 01 August, 2017, 10:21:29 »
Hi :)

My M20 forks have been damaged and re-buggered  at some stage in its obviously eventful passage through the ages.
I am shortly going to start the rebuild(actually they need to be re-made).

So were they originally welded or brazed. There is so much brass around the joints that it almost qualifies as HGV.

At this stage I am assuming brass :) :) :) but open to info from those with a greater knowledge.

The Star and Garter / Sloper value
« on: 28 July, 2017, 09:46:03 »
Greetings :)

I don't recall ever seeing a Sloper for sale in running order with all the paper work up together.

So anyone out there got any idea what a realistic price might be road ready. Or even an expected price.

The dead one on Ebay at the mo is 5500 I am wondering what its value would be(approx) when its done. Not for me I'm afraid but my son is "sniffing".

Any thoughts or help appreciated.

By the way---Anyone heard any news from or about Mahindra. All gone quiet on that front.

The Star and Garter / Sloper
« on: 17 July, 2017, 14:04:15 »
 :) :)

Greetings . There is a 1931?? Sloper De Luxe for sale on Ebay.

Within my totally limited knowledge and experience it appears to be relatively up together, by that its obviously somewhat incomplete.

The asking is 5500. (they spurned my offer of 4000?????????)

Seriously any thoughts on this would be really appreciated. So what do you reckon.

The Star and Garter / motorbike lift
« on: 11 July, 2017, 19:20:03 »
 :)

Hi all.

A few years back I bought a set of plans for building a motorbike lift/bench. I never used it because I bought one cheap from ebay before I got around to it (sound familiar). The assembly plans are fairly detailed and include the full cutting list.

I aint ever gonna build it now so I'll GIVE em to anyone interested. Just contact me here(pm) with name and address. First come etc. Just
throw a couple of quid in the next charity box that you see. Air Ambulance is now my charity of choice. But its up to you.
