According to the data sheet on the AC website (and the fuss on the TY forums) the Yammy 3 cyl runs AC clutches on the AC models....Yam clutches on the Yam models.If I see correctly no Yamaha clutches on any AC machine other than the 7000... Allot of AC peeps were wanting this as the AC clutches have been a POS.
I don't see a good writeup on the new 600 engine. Just a video on the oil for it. I like the idea of the oil container being that bag rather than the jugs.
