My latest purchase. 1961 G80CS.
Very rare bike in Western Australia, only ever seen one other in over 40 years. I plan to complete the resto and ride the wheels off it.
Hope the pic works.

Congratulations on the purchase. I've covered many miles on a friend's 1960 G80CS and it is a very lovely machine. Lots of power and excellent handling on major highways as well as small single-track roads.

Resto ?
Looks like with an airfilter connector and timing cover and tank paint job you could ride off into the sunset.

Nice.
Don't overdo it.
One locally ere gets the wheels ridden off it, goes everywhere..

I have had this bike for a few years and its finally moved to the front of the resto line.
I will have a lot of queries as I am not familiar with Matchless motorcycles.
So, here we go!

There are a few things that need attention.
Clutch.
The lever could not be depressed so I ended up removing the primary chain case and clutch plates. The clutch looks new, no burring on the basket but the springs are too short. The book says 1 and 7/8 inch with 3/16 tolerance but mine are outside this. New springs needed but where to buy, I wonder? Anyone got an idea.


Valve Lifter.
Can not be activated when piston is coming up on compression. I suspect that the revolving shaft in the rocker box is binding on the rocker arm so the rocker box will have to come off to see what is going on there.

Centre Stand

I am guessing there are supposed to be a couple of bushes fitted in the centre stand?

Various unknown brackets, can anyone identify these?

I hope you all had a Merry Christmas and didnt drink too much.

I can't remember much from 1966, but this was my first bike. A little worse condition; it was a 1961 G80TCS, indicating the Typhoon model, 600cc. I bought it for $65, fixed it up, learned to ride, broke the crankshaft doing burnouts, rebuilt it again and sold it for $350 to buy a BSA Victor. Lots of fun riding around fields and campus (private) roads!

Lots of useful AMC info http://www.jampot.com/ club spares also efficient, although delivery might be an issue!

Pictured below, the bottom oil tank mount, there are bits missing, can anyone put me on the right path there? I reckon the upper battery box mount fits to the threaded stud and maybe some sort of large grommet in the tank itself?
The forward cast female threaded boss has me stumped. Wonder what fits there?



There is a similar cast boss on the upper frame, just after it bends down and I am guessing the light switch fits there



Any help would be most appreciated.
Thanks,
Max

The triangular steel plates with 3 holes in are the front engine plates. One or both of the other 2 steel plates may be for the light switch. What year is the bike? BTW there is a stepped bush required for each frame tube if you wish to fit a centre stand. And you are correct that the lower oil tank bracket is rubber mounted. Finally the forward facing bosses on the saddle tube are to fit a steel cover but not sure if they were used on the CS singles with left hand oil tank.

Thanks for your reply, the bike is a 1961 model.
I got it started yesterday, after it has been dormant for donkeys years.

Max, congratulations on turning up a very worthy find!

Regarding your question about the clutch handlebar lever that will not pull in. Check at the right hand end of the gearbox, remove the round inspection cover, and have a peek at where the inner cable engages the release mechanism. In there, you will see that the clutch cable engages a small "bellcrank" (can't think of a better word for it) that creates the release movement. That bellcrank is located against a roller in the release mechanism, and bears against the clutch push rod.

Sometimes when the clutch cable has been disconnected or similar maintenance is undertaken, the bellcrank will slip out of position. When this has happened, the bellcrank will jam and not move. Remedy is to slacken off the clutch push rod adjustment and pull the bellcrank upward to re-engage it with the roller.

Regarding clutch springs, you should be able to get them from any dealer who stocks parts for early Nortons, because the springs are the same.

Hope this helps,
... Gregg

Thanks Gregg, I have sorted out the clutch. Someone had put the wrong springs in there, I got a new set of the correct size, oiled the cable and it works like a new one.

The G80CS headlight plug (below), is there some sort of securing device to hold the socket into the headlight shell?

Anyone shed any light on what is going on with these front forks? This occurs when the bike is on the centre stand only.

The top shrouds are not fixed to the bottom yoke, The screws probably sheared in the yoke and got painted over, should clang well.
Suggests there is zero or little preload on the springs.

Did the later yokes have those screws ?
I've got some shrouds without any holes

[quote=gavin eislerSuggests there is zero or little preload on the springs.[/quote]

Quite so.
Either the springs are too short, or some spacer(s) have been omitted.

There are no spacers missing, according to the workshop manual.
I cant believe that the upper shrouds are screwed to the bottom fork yoke, there are no holes in the shrouds that I can see.
Which leaves only that the springs are too short.
I would post this on the Matchy forum as well, there is a lot of expertise there, but for some reason I cant log on. have to sort that out as well.

Have you pulled the springs out and measured the lengths.
The new lengths are quoted in the Owners manual.

Its quite a common practice to add spacers to make up for any sag in the springs, and add a bit of preload. I recently pulled down a set of forks (not Matchy) and the first thing that came out was the inner race of a bearing - a convenient source of strong hard spacers, perfectly sized - and probably cheaper than buying purpose made ones (?).
