I got 71' honda CB350 twin engine for my kart and I pulled the carbs and there all seized and varnished. So I was thinking of buying some mikuni rounslide carbs off ebay to replace the m because I know more about these. I measured the bore of the current carbs and its 32mm. Is this swap a good idea? Has anyone done this before? I also am guessing that some cafe racer/restorer will buy these carbs for some $ so I was thinking that this would pay for the roundslides. Let me know what ya think.
