Mikuni carb query - MC680x0 - 02-09-14
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/mikunicarburetorcatalog2012.pdf ], I know OEM = original equipment manufacturer but is not the OEM = Mikuni ??

4 carbs = 4 kits, perhaps?
Just buy new carbs, they're a bargain. 8)

I wouldnt call that a bargain mate.
I've decided to pull out the gunsons colortune and adjust the pilotscrews and do a resync; done two carbs today but then had to go and do another job. both carbs were way out and running well rich. sorted now. next steps is to tune the other two carbs then do a carb sync; should fix my erratic tacho needle !

I saw you got the color tune, do you recall how many turns from lock was the air fuel mixture screw turned out? plan to do the same so want to have a rough idea before i step into the unknown.

I suspect darrsi meant that ironically
