Got this SX150 a few months ago. It was fairly original, someone had at one point refurbished it with a few incorrect parts (turquoise HT lead, weird fuel tap, legshield spare wheel carrier). Today I replaced all that by what should be there (I think). It starts first kick, idles well, runs pretty much the way it did when it left the show room! 95kph in a crouched down position.
I also left all the original outer cables in place. Looks kinda cool.
