Mikuni's

Does anybody know where I can find part numbers for the 38 Mikuni's? I'm needing the numbers to the float bowls.

Click on 'Downloads' in the Registered User Menu on the left of the screen - on Page 2 of the 'Technical Documents' section, there's a download of Haynes information about Mikunis. You may find what you want there. I didn't look, (I have DelOrtos) but you never know ...

there`s no such info in those manuals. You`ll have to give your dealer a call or search the web if you find a parts catalogue of a SS, Monster or Cagiva Elefant.

Am i right in thinking that any yamaha carbs from either TRX or TDM are suitable for the Mikuni modification?

Surely TDM 850 1991-95 and 1996-2001 series, but pay attention to jetting.
I use Mikuni BDST38 and found that Yamaha main jet (142.5) fits correctly, but size are quite different (factory M750 is 132.5 and M900 is 140). Also the needle is a different model.

ok, i think i would spend more on jets and needles gettings than a new carb if i got a out of spec from Ebay.

After a lot of searching I've found out that a '97 M750, an '89 Yamaha 1000 FZR, and a lot of the mid to late '80s GSXR's run this carb. I don't know about the jet sizes tho.

ronayers.com has the microfiche for the carbs, but a lot of the parts are NLA. Powersportspro.com has most of the parts still avaliable from Yamaha tho.

It was very difficut for me to find adeguate jetting for these carbs, because Mikuni sell them only as OEM and there are not aftermarket spare parts by Mikuni.

I found that original M900 main jets (size 140) are too small (probably to reduce emissions) and with my open air-filters the carburation was too lean. It was hard, but finally I found a pair of 148 and a pair of 165 (too big).
There's the DynoJet jet kit, but it is more expensive and have different jetting numbers.
