Mikey Dunlop had them for 945.00,but after I purchsed a bottom end,jub,and HD studs,he said he cant get the rod anymore.I hope powroll still can make these.Or if anyone has a 7mm crank for sale please let me know.Thanks
The kit Had
91mm Piston + rings
7mm crank
head gasket
Sleeve

Crankworks might be able to custom make you one perhaps.

I think Mickey bought out Powroll....If this is the one I'm thinking of you also have to mill the cases....good luck on your search.
