I'm doing a search as we speak but the sale ends in an hour so I thought I would ask here while I search through the forums. The 750 carbs are mikuni. I read the Hondaman thread in the FAQs section before which mentioned that the stock carbs on the 550 are more carb than the bike needs leading me to think that perhaps they simply used the same carbs on the larger cc engines as well. I don't know if that's the case which I'm hoping you can answer for me while I do my search.
