Bomber crank refurb
AshimotoK0:
My good buddy Graham Curtis just sent me this pic of my rebuilt '67 Bomber crank ... sludge traps totally full of crud but otherwise just needed stripping and cleaning. Evidently the copper coating is part of Honda's original hardening process.
We did a deal where I gave him my three spare cranks I got from Crawley (well 4 actually as I gave him one to 'experiment' on last year ;D) .... to make me one good one and used the rest for other peoples refurbs.
If you have a pressed-up Honda crank ..Graham is your man.

That's what I thought.
It makes it almost impossible to build a 6

my understanding
CB400F ... CB500/550 /4's , CB750 SOHC's have plain bearing one-piece cranks
Z1 /Z900 cranks pressed -up roller bearing
Z650 Plain bearing one-piece crank
GS550 .. GS750 .. GS1000 crank pressed-up roller bearing .. so you could make a Suzuki GS825 6 /cyl from 1.5 GS550 cranks :)
