That Y boot is the magic trick for all RD motors.

teazer, do you think those y boots would work on a 400f? If so it would probably save me money from buying 2 extra carbs.. just get two CR26 (maybe a size up?) instead of 4..

Good question if we think of it from a different perspective.  I'm not a fan of single carbs for twins or twin carbs on 4s unless the crank is re-phased to suit and that isn't either practical nor a good idea in this case.

CR carbs are the ticket but they are not cheap and unless you are racing or have tons of surplus cash, there are other options.  In the day, a set of 26mm (1") AMAL Concentrics were the way to go.  Maybe there's a similar set of say Kawasaki KZ650 carbs that would work better than stock carbs. PJ probably has some ideas on that.

 Isn't it a stock Yamaha piece?
 Damn, it's a long time since I worked on them
 Should work to fit 2 filters on a 4?
 Won't CB550F1/F2 carbs fit 400?
I've used Suzuki GP 100 or 125 carbs, use early CB750 1:4 throttle cable (doesn't hold sync very well though)

Yep, stock and still available from Yamaha on the unmounted engine.  (NASA spec coupling to the air cleaner is made from baked bean can!)

This is the Bridgestone 200cc rotary disc valve twin two stroke engine that we built for the Bridgestone motorcycle we are restoring for Brother casi. Here is a link to the build if you would like to see all of the photos http://www.dotheton.com/forum/index.php?topic=32957.0

I love everything except those carbs.


I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.

Don't you mean rotary VALVE twin, rotary is usually a Wankel engine
