Primary drive rubbers and gasket set not in picture. Let the fun begin! 😁 (Attachment Link)

Eye candy - lovely what make are the pistons and who did you source them from I'm pretty certain I might end up needing some early next year.

The pistons are unbranded Japanese from Cruzinimage. They seem good quality and a very good price.
They arrived after just 6 days!
McCabe-Thiele (Ted):
Hope you can post some pictures and details on fitting the pistons to the barrels. In my mind it looks impossibly fiddly presumably having to fit two at the same time then the second pair fighting against the weight of the barrels unless you have the engine on it's side.
It looks as though gudgeon pins just push through the piston & the little ends with a clip on each side or are they an interference fit as well?

Like everything it takes some practice :)
Just cut some wooden blocks to the right size to support the barrels halfway up, and take your time.

Will do - if I've got a spare hand!
The gudgeon pins sometimes need a bit of heat on the piston to slide in or out.

Don't forget the Hondabond for the case joint!
Time to make a cuppa and get started on the adventure :D
Good luck and keep the progress photos coming.

Yep. Got a tube of Hondabond HT. Forget to put it in the pic.
I haven't added up the cost yet, but got the Kawasaki primary chain from MSP, piston set from Cruzinimage
and o-rings etc from Nurse Julie so did quite well on prices. 👍🔧🏍

Did a quick add up. Comes to just over £300, a bit more than I thought!
I've still got to get a couple of small things like new Dowty seals for the head.
The ones that were on it are well past it.
