Both are 650 based engines, extremely hard to find, especially complete with matching pipes.

Cycleworks Reed valve converted 750 with PSI Genesis head, Genesis race pipes $2200

Both motors need some work but the bottom ends are rebuilt. Cryoed and welded cranks.

Two sets VM44s

1 year old primary clutch precision balanced, several extra clutches, springs, weights, billet helix

Triple Digitron

A lot of trick parts here.
