BIMOTA DB1 Regulator Replacement – Shorai Battery Conversion

I’m captivated by the Dellorto logo. Truly Italian craftsmanship.

The regulator is apparently hidden under this panel.

P1640758
I’ve never seen anything like this before…

P1640759
Strange design—is it a retaining feature? Waterproofing? Curious.

Just touching it and it crumbled away.

P1640761
When I pulled, it came apart. In a way, good timing.

P1640762
It had turned some indeterminate color—red or yellow. I traced it back to confirm, but now I can’t reach it.

The yellow wire has two cores.

The customer sourced a Shindengen regulator for us. We’ll install this one.
Grateful it came with instructions.

P1640765
We remove the oil cooler and pull the case out from below.

P1640764
The battery fluid was completely empty. No wonder it wouldn’t start.

P1640766
These days Shorai batteries come in various sizes, which is great.

P1640769
We keep various terminal covers in stock—straight and angled.

P1640767
Based on the layout, we went with the angled version. Since the battery is lighter, we secured it with a band to keep it from moving around.

P1640770
Before starting, it had already climbed to around 13.8 volts.

P1640771
Switching to a paper gasket stopped the cover leak, and I’m oddly pleased about that.

All done.
