Having read the mototune and wiki info before posting questions on the subject, and having re-read them a few times, I am confident this seems the best way to go. Afterall niether of the texts suggests burning it up like some boy racer and potentially risking damage to the virgin engine. They direct towards steady strong pressure to load the piston rings through the middle gears, to ultimately seal that all important part of the engine. I'm going for it!

, you mentioned you should
never let the engine idle, Why is that?
Lots of people leave there engines running for 5mins or so on a cold morning. Is that meant to be damaging or just in the case of a new engine with regard to warming up?
