My project 1955 18s
Purchased on Ebay for an appropriate exchange of funds the bike travelled home in the trailer in bits and boxes.
I've wanted to do one of these for ages and this one came up built in my birth year so its only right.
The seller had taken the speedo, thats a bummer and will be a trick to find however the rest of the bike is mostly there, importantly the tinware and frame are all in good nick apart from the front mudguard which will take a bit of work.
The cylinder head has had holes drilled down through the fins to aid cooling I presume, that head has been replaced with an unholy version.
Anyone want a head with 50 or so holes drilled through the fins?
Progress so far the bottom end has been completely rebuilt with bushes bearings and oil pump all replaced with new. the barrel as been sleeved back to standard with an new piston.
The new cylinder head is being fettled at the moment, the valves and guides are new , the seats re-cut and the rockers are being rebuilt shortly. we are lucky to have an engineer in Adelaide who makes a lot of AJS parts including the rocker arm spindle sleeves, I'm just tracking down a set of springs and spring seats and the head can go back together.
The gearbox internals were in brilliant condition I've just had to replace the kickstart and gearshift shafts and bushes and oil seals. the gear shift was not included and so i've cut down a kickstart and made a gear shift from that, it will look awesome chromed up. Cams Have been sent to Newman's In England for refinishing and are on the way back right now.
Getting close to the painting and first assembly.

I remember seeing this done to café racers in the sixties - the reason given was to improve cooling.cbranni wrote:I don't understand the drilled holes in the head
Strange as the net effect will probably reduce the surface area of the head and thus will reduce the cooling effect

Here's the picture of the head, they would have spent some time on the drill pres, it looks like they was working on the principal of the more holes the better, perhaps they should have taken the fins off altogether that would have been perfect.cbranni wrote:My thoughts exactly Mick, oh well

Perhaps it's to make a loud screeching attack sound like a JU 87.
