MONSTER Spree

Reed comparison for my Black and one of my regular CT.



The Black has a single monster petal on each side of the "V" while the regular CT has 2 petals on each side with a divider in the middle of the reed block.

6 pedal reeds that came with a ct chrome vs BIG CT black reeds.

Here are a few different comparison shots

The reed stops are also restricting the air flow. My Black has NO reed stops, so the walls of the manifold are what restrict how far the reeds can open, which can allow a higher maximum air flow which raises max RPM = speed.

These reeds fit the BIG black intake............no restricting reed stops here.

I also have a Big ct... there is not much to compare between the std CT and the Big CT... as the pic shows it has WAY more reed area.

Bear why do you have to always argue even when its obvious your wrong?

Why do you fear another view? Oh and I am not wrong. My Black has a totally different reed set up than any of my regular CTs, 4 or 6 reed. and in my opinion it is better than the one that Tjamz has.

im guessing your reeds are the dual stage reeds that come with the ct black aka stage 6/koso/bgm(not big black like traffic's)

[sum-azn-kid]

oh and traffic thanks for postin up them pics of the ct big mani. copared to the standard

[Bear45-70]

Nope, they are not dual stage. Single petal, single stage and there is no cross bar in the middle of the reed cage opening.

[sum-azn-kid]

ya... that the ct black. but there are some extra reeds with it that are dual stage.

ran that intake on my sym.

OK enlighten us... why is your CT Black superior?... not because it has more volume... nor larger more unrestricted reeds.. and they are both black... I give up... its better because... wait I know why... because its yours

[Bear45-70]

A single big hole will pass more air than 2 smaller holes, even though they are larger in area, because they have more surface area which lowers air volume. All of this is basic physics and if you are unaware of that, I am sorry that your education is lacking, but that is not my fault and does not make you right.

On another note, the numerous openings, as in the 6 petal reed (especially the dual stage reeds) set up, is better for drag racing with an automatic, in this case as CVT, transmission. Why because they will keep the air velocity higher at low RPM, there by help the engine make low end torque and improving the 60 foot times and the ET. But again this is all basic 2 stroke stuff.

Your should go back and learn how to read.. or is it your memory thats gone?
I never mentioned 6 petal reeds.

The total reed area of the Big CT (4 petal by the way) is way larger then the area of the smaller CT also with 4 petals.. or even one with 2 petals...no way to flow more air through the smaller area of the small CT under the same vacuum... physics also.

This thread is about a 125cc build and the big CT was made to work better than the small CT with the big CC strokers while the smaller one works great on smaller CC motors

Build a big stroker and run both setups... like others here have... your all talk and no action old man.

Oh... who wants low end torque at the drags with a scooter... we leave the line at around 10000 RPM.. at the peak of our torque range

[Majourlittle]

Even if the big flows better than the regular, is the regular ct at choked flow with a larger displacement engine? It seems to me that higher velocities through the intake would produce beter atomization of the fuel. In that case, wouldn't the big ct cause slow air velocities in moderate displacements?

You say way larger, but 2 holes with 20% more area will equal one smaller single hole.

The size of the motor is irrelevant. The basics remain the same and apply equally to any size motor.

I started drag racing back in the early 1960's. I don't need to go back to school.

Every racer that knows their stuff knows that ET is about the first 60 ft and the first 600 feet. Big mph means you have thrown away ET for a big mph number. I am continually surprised by you lack of knowledge of drag racing.
