Colder air has the same % ratio of Oxygen to (mostly) nitrogen, but there are more molecules of both, as the air is of a higher density.

Can you gimme a link to that, it sounds really interesting,

Have you seen the thread on kiwibiker forum? "ESE's works engine tuner" has 1018 pages at the time of writing this.

Got to have a gander at the pitlane thread.

Great read on this thread. Bought an rs125 out of boredom to revive a beat up, abused by a 17yo, little stroker. Having worked on my own 2 strokes for years and tz250 gp bikes, I have a good grasp, just wondered if Greg was still making airboxes rather than me making my own? Want to get the barrel ported too, with a pjme or abstract head at 0.9 to 1mm squish, I'll be running a 50,50 avgas,99 octane unleaded pre mix. Is Greg still porting barrels or shall I head to Mick?
