As I understand the carbs are type BSR33/4
- what does the /4 mean? I thought the number was the diameter so 33mm or 34mm types?? but the Yam shop manual states BSR33/4 so does one read this as "you can fit BSR33 or BSR34"?
- why can't I find any guides for tuning/overhaul at their own site: http://www.mikunipower.com/manuals01.htm.
- when Mikuni talk about the BSR33/4 being OEM on many Japanese machines [on page 33 here: http://www.mikunipower.com/catalog/mikun...og2012.pdf ], I know OEM = original equipment manufacturer but is not the OEM = Mikuni ??
