new pistons

Decidied that the GPZ900 pistons will have too high a compression so I've done some digging and come up with Honda transalp pistons at 74mm.

just bought  some GS500E cylinder liners and had them machined OD 81mm and will get them fitted to an enlarged cyl and crank mouth.

I have also got  another engine so if it goes pear shaped, I have a back-up
