if im setting the timing on a bike, it can be referred to as either in mm before top dead center or degrees before TDC, correct? to convert from mm to degrees BTDC, is it as simple as just saying:
2mm before top dead center = 2(360/stroke)
360/stroke gives you the ratio of mms to degrees... multiply by 2mm and that will give you how many degrees?
for example. stroke length = 41mm. 360/41 => 1mm = 8.78 degrees. times 2mm = 17.56 degrees... is that correct? that seems like a bit much.
as i think now i realize it could be 180/stroke? i dunno. am i warm?
the reason i ask for this conversion is because i'd rather set timing in terms of degrees over mm is i feel like i could measure it more accurately.
i mention wari because i know she knows all sorts of special things like this (this is probably pretty basic knowledge for someone who know's their ish)
