Last night I bought an '03 CR250. The bike looks real clean and obviously doesn't have much time on it. I ripped it apart tonight to get a closer look at stuff and noticed that the reeds are carbon - do these come with stock carbon fiber reeds, or has somebody replaced them? The Mikuni TMX carb doesn't have any wires leading to it - I assumed this bike would have TPS. Did somebody swap carbs, or did these come without TPS? Thanks.
