描述：My first ever field sound recording, made with diy mic and Sony MZN707 MD, sp mode, mic gain set to "low". Tommorow will make some more :) Gilera Runner SP50, 50 ccm 2stroke scooter, with removed factory speedlimiters (some of them are in the exhaust). Mic was positioned maybe and inch above exhaust. At the begining automatic choke is engaged, hence the high idle revs.
