Anybody have or know where to access a cross reference chart? from Yamaha part numbers to Mikuni part numbers. Main and pilot jets are pretty straight forward but needles, needle jets, and slides are a little less intuitive.
It seems easier to find genuine Mikuni parts (needles and jets etc.) if you know the Yamaha number. Everyone hear speaks in Mikuni #'s while Ebay is full of genuine Mikuni pars but they are listed and packaged under the Yamaha # even though the actual part in the Yamaha package is stamped the Mikuni number. I feel more comfortable buying by the Yamaha # in Yamaha packaging to avoid sub standard knock-off "Mukuni" parts.
Thanks Jeff
To my knowledge there isn't a cross reference chart. If you're looking for RD info it wouldn't be difficult to make your own spreadsheet, as there are only a few parts to deal with. And keep in mind, some parts are NLA.
I started a spreadsheet a while back and your right RD's and R5 are pretty easy. But I have several DT's and those carbs are all over the map. When I finish it I will offer it up here for anyone interested. Ebay is great for NLA needles and jets, lots of NOS Yamaha / genuine Mikuni if you can navigate the PNs
I just threw this together
