I did get a response even though they are in the process of moving. In the US the 19% tax does not apply. As shown on their site, one would get everything needed except the coils. I asked for a recommendation on that as well. There are instruction manuals and schematics for download. It has 9 different curve settings in the system. My bike is perfect for this. It started as a 1980 touring. In the end I plan to run some standing miles for speed. I've completed a 100% hand made exhaust. Redone the wheels and brakes. Did some additional drilling of the rotors and just finished the panels for a new gas tank. Next is a tail similar to cafe racer styling. I have some neat ideas to lighten the bike including a street rod style aluminum radiator. Did some pretty basic port work and am looking at cam re grinding for a but more cylinder pressure.
