Nice !

Just made these, as the 2mm thick lug on the late twinshock bikes has a tendency to fail. The replacement is 3mm thick!

Water jet cut... Nice looking good andy

Just been playing with our new 'toy' which make 3D rapid prototypes...



Also, just finished the vacuum fixture to make the MX rear brake plates...

Andy.

yeah Andy ...
the reedhousing is exactly what I need for my 81/82 430cc ... adapting new reeds to old type of cylinder

So much easier to print than to manufacture....

3D printing offers a whole lot to small volume manufacturers. A big part of the cost is producing the pattern, are you keeping up with the times Andy, or like me you have a love of "gadgets"

Yes, good to stay up to date with the new technology!!!

The difficulty is that the carb will have to be further from the cylinder to make room for the new style of reed block.

The carb will need to go towards the airboot by 12 - 15mm to get it in.

Let me know how you feel about that please...

We should be able to try this one on a bike - as long as we don't get it too hot!!!

Andy

As long as there is an adapter kit available if there is a problem it should be acceptable.

what are these?

looks like the twinshock 83/84 exhaust mount tabe welded to the frame under the seat

ah yes...had nothing to"scale" them to.

took me a minute as well!

Andy.

Andy- how about some pro circuit chain guides?

Some guys were using later Evo guides i heard. These look pretty easy to reproduce?? Andy?

No, they are all rubbish compared to the genuine parts! Gas Gas even use the old bits up to about 2008.

If you catch any of the Alloy guides in a deep rut they bend.

Don't do it!

The only ones that might be better are the solid urethane guides that some modern bikes use - as they will bend and go back into position - but they are not 'retro' enough for my liking

Andy

Here are the 2 latest developments from the Factory!

Twinshock Brake plates (Evo to follow)

And some Titanium Wing nuts now that the Genuine ones are out of stock!

Hope you like them!
