Hi all, i have CR125 2007 with big bore kit (144cc)
I had PWK 36 short body type on it and i decided to purchase the STIC metering block
My initial jetting (with the pwk blok) was; 165 main, NOZH 2nd clip, 48 pilot
The bike ran great on sea level with lots off low end crisp power
i have just installed the STIC metering block it is .114 tube with 180main, NOZH 2nd clip and 48 pilot.
The bike pulls hard and very good from mid to top but it’s running way too rich down low
Now, i can start try to jet it leaner and try to dile it in but i am afraid to ruin my motor
Right now i am preparing my bike for enduro with lots of slow tight technical terrain so i want to solve it quick or I will have to go back to the stock carb and loose the mild to top hit that the STIC gives
Any one with experience in it?
Any one have George Bosewell email adress?
Thanks

I am not sure about the air screw, i simply adjusted the it untill the bike was idling well
The Shop
Just installed the stic and started riding
Even cold start is pain in the ass...
I hope that this is the problem
Tried the NECJ and didn't run as well with it.
Pit Row
Because the jetting supposed to be different between the 2 (i have 36)
Do you have any other needles?
What did George say?
Where i live dealers are not holding stocks like that
Waiting for him to answer
I will order the 52 pilot and try it
There’s a holiday here, Tomorrow our Yamaha dealer will be available and i will purchase a 52 pilot and N3EJ neddle
Voice of Robert: “I have tested the STIC metering block; “Here is my review of the STIC metering block:” “The invention of the STIC metering block and methodology may be one of the greatest examples of a superior engineering design that controls air-fuel elemental molecular vaporization and the rate of the air-fuel-vapor flow rate into the engine based on the STIC’s ability to sense changing engine dynamics; driver, and landscape demand changes including changes in temperature and altitude.
I have carefully tested and reviewed the STIC block and STIC tube. This includes its claims and various features. I have talked with the inventor and here are some of the STIC features that I agree; they are true as claimed after my review: (1): The STIC system appears to more effectively utilize the available oxygen no matter where it is in terms of altitude and temperature. (2): The STIC auto-selects the prevailing higher pressure; choosing from atmospheric and the engines fluctuating intake, combustion, and exhaust pressures. This feature allows the carburetor to create a higher differential pressure drop [vacuum]; thus causing instant air/fuel vaporization independent of engine suction. (3): The STIC has an acceleration system that auto-loads; thus having instant acceleration from all positions including low rpms. Due to the fact that the STIC system is able to sense engine intake demand and pressures; it has the ability to have a broad jetting range and it appears to know which engine it is on thus requiring very little changes in jetting. This is confirmed by comparing CSAR’s 300 with TOKYO: Mark’s (Japan) 250 utilizing similar jetting verses Phil’s 300; they have identical jetting as CSAR’s jetting in New Mexico at 5200 feet. (4): The STIC has a power system that does not need power wings, power jets or small carburetors. The pilot jet is now part of the STIC power system that blends the pilot jet fuel and its related air circuits into the jet tube outlet; this is one of the reasons the front air screw and the larger pilot jet is part of the equation. (5): the inventor tells me the optimum should use a #6 slide; and reports most applications will want to use the 38mm carburetor as you no longer need the smaller carburetor to cause it to trigger. The inventor also reports there will be a new air screw and idle speed screw coming soon, and there will be new STIC needles on the horizon that will come with the STIC metering system.” Robert Engineering.

I have ordered 38mm PWK with the right set up but it will take 3 weeks before i will get it (crazy Israeli customs cintrol...)
But i found the NECJ in my tool box
