If it is an L model SP it will have a mitsubishi CDI therefore the crank trigger will be three lobes instead of 4 ( 1 small lobe and two large). It will have a close ratio box, and as it tells you the standard tooth counts in the manual you could check that. It will have SP cams which have adjustable sprockets instead of fixed. L models ( or M actually) had Flatslide carbs as well. those are the most obvious ones. cheers.
