Anyone have any opinions on what exhaust to get and where? Also has anyone found that the 230 exhaust can be used among the other letter models in this class such as the G ,S, and EH models. Or for that matter can the Lt 250 exhaust be used on the 230? I would like to get a performance exhaust,KN filter and new jets as well as a set of wheel spacers to widen it's stance a bit. Let me know of where I can still find some of this stuff for the 230. By the way I have the orignal owners manual and such for mine and if you need a copy let me know.
