hello Kev,
Yesterday it comes from Czech Republic,
it has 360 degree spark.
I read its for high compression and modified bikes.
Developed specifically for the Lamborghini.
later they adapted motorbike.
they said at 1000 cc bikes provide considerable power increase.
then bought it ebay 18 usd including shipping and came in 5 days.

as a first impression
last my Co setting 12 I did 8 then
Sudden throttle when I idle, the engine was stop.
do not stop now, and more precise throttle.
or I felt like that.
