Adjustable timing wheel for NB

As used on the Stage 1 turbo kits for the NB, this simple wheel replaces the stock trigger wheel on the crank nose. Unlike the stock piece, it leaves a bit of room for adjustability. The ignition can be retarded by up to 8 degrees or advanced by 4 degrees.

Adjustment consists of simply loosening four bolts on the crank and rotating the wheel. An indicator shows you just how much you’re retarded or advanced compared to stock.
