The Standard ignition requires the exup valve to be connected for the ignition to work properly. It also requires an aftermarket derestriction box like M Max, the bits and peices from the rear of the spedo to be connected and the side stand to be isolated It also has a 14,500 rev limiter.
We are now able to modify the standard ignition unit to make it exactly the same as the kit ignition,(15,400rpm, advanced curve) it has the same ignition timing and the exup works at the same time as the race kit unit. This no longer requires any of the ancililary's (exup motor, m max, spedo bits and peices or side stand to be connected,)
From the bikes we have fitted these to, the difference is bettween nothing and 6bhp.

If you are interested I can send one for testing/evaluation, and refund you if you don't want it.


As far as I am aware the kit ignition numbers are:
3TJ-70,71,72
82305-70,71,72
everything else is either standard UK spec' or restricted.
The restricted ones have a 3 pin connector and 3 wires coming out of the center of the box. The other wires are for the servo motor.

The cost of buying a modified unit is £240.00 +vat
