Hi All,
You have had some good answers.

1/2 - You're on to the actuation arm, that has been changed as Rod suggests to the James Hunt spec actuator and has been lengthened as well.

Probably the single biggest improvement to the actuation of the clutch. The original arm had three ramps that the arm would slide upon to raise/lower whereas the new actuator has ball bearings sandwiched between ramps on two plates that allow it to move more freely.

3 - There is an extra friction and steel plates in the clutch pack.
(I'm not counting the dodgy screws David as they were out of necessity for thread engagement)

I wanted to reduce the force even further to engage the clutch and the only way to do this was to reduce the rating of the compression springs used to preload the pack. To stop the clutch from slipping and maintain an equivalent capacity I added another friction surface to the system in the way of the extra plates.
I was able to source some slightly thinner friction plates and I surface ground down all the Steel plates 0.1mm to maintain the original pack height

4 - The counter weight has been removed from the end of the crank and swapped for the much lighter nut used on the Aprilia Climber bikes.

Apparently there's some interest in seeing more Greeves.

Here's Don Smith's highly modified bike for the '62 SSDT, said to have "nearly 30lb" pared off it, bringing it to 210lb

Then what must be the ugliest trials bike ever produced, the TGS Anglian of 65/66 with banana forks

They look somewhat better with telescopics: the TJS

Of course Bill Wilkinson won the Scottish on one with Cerianis in '69, said to be a two year old bike then

And the ol' lads in England used these as commuters too. Good old gear.
And on Sunday they'd be up at Canada Heights (Farningham) or somwhere, hackin' it through the mud!

That must be the only Greeves in Oz trials Shane.

Here's a few of their Pathfinder. They tried to make one bike for Trials and Enduro with different seats, different footpeg and brake location, and a 1" longer swingarm for the Enduro.

Now that's a gusset!

Seems to be the bike Beamish entered in the SSDT in '76

Looks remarkably like what comes standard on a Bultaco. They really should have made a closer copy of the Sherpa T

Hi Everyone,

By now you have probably realized that WE have hit a milestone, yes I mean WE because without all of your input Basket Cases would not exist. So thank you to Everyone for joining in, contributions and photos, got to LOVE the photos!

There have been times when I have laughed out very loud with some of the comments and explanations of how people see things! Yes, even some of the Puns!

The information shared here has been exceptionally enlightening, entertaining and extremely helpful to me and I am sure many others.

So Please carry on, well maybe I don't need to tell anyone that?

What I mean is Please continue to contribute and if you are just a reader, Please get involved? Everyone has a story and sharing that story, even if it is exaggerated is very entertaining and nice to read!

OK, just sharing the reason why I contribute:

My vision was to build a reference, storage bank if you like of information to use in the future of anything relating to enjoying or riding Old Trials Bikes. So Please share your information/ stories/ ideas/ reports of conversations around the campfire from back in the day/ anything relative, oh yes a little humour goes a long way? Leaving breadcrumbs like SIX ZEROS, Keywords in the heading will help us find it later!

PHOTOS, got to have PHOTOS :!:
