Hello again.

The tuning on my bmw r1100gs is continue.

I think to use two ignition coil parallel for better fire spark. The bosch coil gives up to 12.000 Volt. I dont know what happen and how long will be the voltage by one battery. Have anyone some idea how to make the connection by register or by AC Adapter for the seccond coil ?? I will try to use an AC adapter for low voltage at the second coil. Etc 12 V for the first coil and 4-6 Volt for the second. So i think that the new high voltage on the spark being 14-16.000 Volt .
I want to make my R1100 gs to gives up 8.000 rpn. I make new camshaft and new pistons, compress ratio up to 12:1, free air and exchaust..

Now by my old setup, with ratio 11:1 and camshaft from r1100s, the engine gives until 7.500 rpn and i think the power could be continue up to 8.000 rpn. So i need more compres ratio, more fuel, dual pin plug sparks.
The dual sparks is this one (NGK BKR6EK) and work fine on R1100GS :
