My ZXR400RR needs a spare heart

[RebuilderGuy]

Hi guys/gals, Rebuilderguy here.

My little "Sparrow" has had some time on track. But the valve seals went. The engine is at the shop now for a full rework.
But i was wondering is anyone had a spare (healthy) race engine for the zxr400.

pls contact me on the forum, or whatsapp me at 06-55913611

thanks in advance!
