have you install, a hid xenon kit.
Most problems , starting with install a Xenon kit.
the usa busa's have start up with lights on.
The ballast pulls , so much power from the batt.
That needles hang on crazy positions.
you now, you have a half tank of pumpgas yesterday.
This day you start the Busa with xenon HID on .
And now , you have a full gastank needle on the meter.
I had that problem, a month ago.
Drive through my hometown, and still the needle stands on 170 KPH.
In fact , the speed was 50 KPH.
So put a new Batt. in Yuasa YTZ 14 S 225 cca.
And NO problems , since SWAP the Batt.
