match the intake

[DA-zoocrew]

hello all MB-people,

i have a question or 2.
attached a pic to try to explain.
i am in the process of installing my new motor,
was removing intake and exhaust studs to put
the blue loctite 242 on them.
i read the threads about the benefits of matching the
exhaust port and the exhaust header/ pipe.
SO,,
i already opened up the exhaust header to allow
better exhaust flow.
now i've reached a point where i'm stumped.

the Question Is...

should i try to match the intake manifold to the motor?
because there is a huge difference between the
cylinder and the intake manifold.
if yes.
all the way to match the cylinder.
a small amount
or don't even bother with it.

Matching won't truly be matching until you make the gasket match, too.. Is there a carb with the same area in the inlet/outlet, too?

OK,
Update.
i have now matched the gasket to the cylinder,
and matched the manifold to both of them.
i also took and matched the manifold
inlet to to the carburetor,
i could of ordered a bullet intake manifold.
but were is the fun in that.
LOL,
speaking of the carburetor
DudeZXT i have the
High Performance CNS Carburetor. its in the pic i just added.

i do have a question about that
it has a plastic sleeve where you slide it over the
manifold.
that peace looks a little sketchy, should i replace
with something different or just remove?
thanks for your suggestions.

NEXT.

cut up the exhaust pipe, bend new pipe add expansion chamber
all to run next to the frame and exit to the right of the rear rack.

I bought one of these for my exhaust. I cut my own intake gaskets though.

This is how I make the intake gasket. MM intake and a ink pad along with high quality gasket material (card board). I also put a light coat of Permatex on both sides. I can take the bolts out of my intake , grab it and pick my bike up off the ground.

The guy I got the aluminum exhaust gasket from has re-listed another one if anyone is interested. Was less then 5 bucks and he got it to me from Hungary to New York in 5 days.

His are cheaper then buying a paper gasket from someone here in the states.

Go figure.......

That plastic sleeve is a rather essential item- it allows the carb to properly fit on the intake manifold. I've had some issues with the Del'lorto carbs on the DiBlasi R7E engines- some of the intakes were so worn from inept repairs, I had to find a way to keep the carbs on tightly! It's a pain in the butt when you are on a dark road...and the carb comes off!

I found 2 methods that are working very well!
1- Minor shim: I took a strip made from a beer can that I made to the exact width and length I needed. After curving it on a socket wrench handle, the strip worked great as it provided enough filler for the plastic ring to grab and stay on the manifold.
2- Major shim: I had one DiBlasi where the carb would not stay on..and I broke the plastic ring! So, I cut some brass shims and after fitting - this carb is bulletproof!
