LS3's are good little bikes. Mate has one he's had since we used to race together to work in the morning [he's 70 something now], he put a bigger carb & a quiet chamber on, bit more comp & went like hell. I had an AT1 [piston port] so one day i fitted a CT1 [175] top end secretly and went past him changing up--haha, take that. Anyway, good little motors. At work we 'did' have one customer that had a 4 speed version, i think with neutral at the start like an AG but he was an asian student and might have bought it with him from overseas as only recall selling 5 speed ones. Thanks. ps, google image LS3's, should be heaps. Same mate--i bought two LS2 100 twins off a few years ago, they're neat too--still have them.
