Splitting the carbs is a rare event in cases of carbs damaged by impact or
breakage.  They still offer each carb separately, so it is not an impossible
situation to accomplish and re-adjust.  Special attention should be given to 2
main points.  The roller on bottom between the carbs being properly fit back
into it's guide bracket, and each carb has on its inner body side, an index
fitting point that aligns both to each other. Kind of like a protruding cast
molded point and hole that fits together like a puzzle. A good practice for
those who havent done these units over the years, should consider taking step by
step photos with their digital camera upon disassembly. It really helps alot
having a guide for re-assembly.  BTW,  have you ck'd the metal piping along the
leftside of the frame between airbox and carbs. Those are dual piping that small
critters like spiders and mud duabers love to build nests.    The large
airbreather hoses on the
carbs attach to this piping. Be sure and blow compressed air thru the tube,
cking the flow on the other end with your hand while the carb hoses are off.
Also,  when you remove the intake manifolds, are you cking the oring between
manifold and head for damage,worn flat or even some rare cases, has fallen out
from previous repairs and not noticed.
Should you get to the point of giving up, I live in South Austin and perform
bike repairs on the side.

Hi,

I have my brand new P901 manifold (one of two actually). I am really
interested in getting a HSR 42. I have let TWO GET AWAY on ebay!!!

My dual carbs are Jekyll and Hyde! One works fine and the other is way
too lean. I have fiddled with it until I am tired of messing with it. I
am considering splitting the carbs. I have had them out and back in 8
times. They are "linked" in 4 places. The diaphragm covers, the throttle
linkage housing, the throttle linkage and the choke. The attach point
for the throttle cables from the handle bar are on the bad carb. The
attach holes for the bracket are not tapped. No biggy. Every attach
point is done with "c" clips. The manual says that once split, they
impossible to re join. I don't see the big deal, but I am not a Yamaha
engineer. Has anyone split them? What are your experiences.

CCworks.org has the rejetting info.
