Look at the bent metal part of the plug and it will start to burn clean at the tip ( burn back ) . Advance it 1 degree at a time until it burns back to 50% and you are safe IMO .
As another guy says - Tune it like Paris Hilton --- Rich and Retarded
2institute - what bike is that graph for ?
I too would like to install a ignitech or zeeltronic unit , it is all rocket science to me at this moment .
