I swapped out the Keihin carb for a Mikuni VM34 on my daughter's 1978 ET250 just now. Man, what a difference!!!! I need to fine tune it a bit, but this thing runs a whole lot better than it did. Many thanks to Chibravo (Don Brink) who spent considerable time on the phone with me......... talking me into doing it, and giving me the step by step process, and to the rest of the guys who posted info/pics on the topic long before I got here.
