Well, I want to have my audio a while and at the moment I get used to driving around on a moto-friendly way. i.e. I start right after the start (no running warm), turn it as long as it has no 90°C not over 3000 rpm, switch to the next higher gear with 2000 turns. use syntetic oil. and don’t chase it over 4500 turns what would increase the life expectancy of the engine and the getiebe?
