Hi,

my english is bad, so i doesnt write all the think that i could write.

Name the Parts? There's normal Motorparts (Pistions and so on)

I clean the Head and mill a little "combustion chamber". Without sharp edges the pinging risk is lower (other changes at the pistion)
The Exhaust is finished, but i had no photo on my PC :/

The Valve are standard, but the valveseat is changed an the valves milled to be lighter (lower springstiffness -> lower losses)

The data in my last post are simulated. But the Motor (when finished) are fine-tune on a dyno.
