Well she went back together but not without a fight. Snapped one of the Rocker assembly bolts Lucky it was just above the head so i could grab it with pliers and screw it out.
When it snapped all sorts of bad things went trough my head and a whole lot of very colourful language was heard around the street lol
Now to tune it up

Wrist bore offset..?
Question for anyone who knows:
My stock 883 pistons have a wrist bore offset that is designed by HD to balance the piston under load.
I noticed another big bore kit also has the offset, BUT it seems Hammer don’t do this.
Their instructions state pistons can go either way if valve pockets are identical which they are for stock heads.

So, I’m wondering why. Does Hammer know better than HD on what would be critical for performance, load, longevity and wear?
Instructions from other kit maker:
