HONDA LA250TCUSTOM

Safe packaging, received perfectly, good quality, easy fitting. Installed on CB400SS without any issue

Aprilia RS125 MY08 Although IW01-31 (an equivalent for NGK No. 10) is usually used for racing chamber specification, only a winter season raises the main jet No. 1, and is using IW01-29 (an equivalent for NGK No. 9).

HELLO I'M SATISFIED OF THIS PRODUCT. SO I NOTICED AROUND 5000 RPM ,THE ENGINE SEEMS LIKE TO HAVE BLOWS. AS IS AN RACING PLUG YOU HAVE TO MAINTAIN A CERTAIN POWER FOR AVOIDING BLOWS.UP 5000 RPM YOU HAVE GOOD SENSATIONS.

I exchanged Plug because it exceeded 11000 km. Although it is an impression of about 500 km,
The attachment of Axel at 1500-3000 rpm improved, and the high rotation also turned well
I think. 5 speed 40 km is easier to run. Just 2000-3000 Partial
I feel that the area became irritable, and it became difficult to maintain a little with. I want to increase the vibration...
Because the heat value is not matched, the original Plug may be more comfortable for regular rotation. I am worrying about returning..
Looking at you..

Thanks to this main jet, the best setting was decided.
I added it in autumn, I think that it is a CVK type carburetor and it is good to have a setting that can be used throughout the year.
It is a really small main jet, but its role is really Large.

I installed it in SC 57.
It is an impression of an amateur.

Full power
Power commander installation (Map is DL from Site)
Comparison with OEMPlug.

Idling is not stable.

It gets stuck at low rotation.
Especially when you start off on a town ride it will be noticeable.

Also, if you cruise around 4000 to 6000 turns, After Fireia will happen. "Pan!" Although it is not quite so good you will hear a pom-pombolic sound.

I feel that it is not much different from NORMAL around the power band.

Can you feel the difference when you run Circuit.
In town riding this plug was unnecessary.

I bought it for Setting of CVK 24.
Set is cheaper, but it is troublesome to get expensive as these odd numbers are bulk selling. Although it is a little less than 500 yen, it will not be foolish if you buy a few, and it will be in vain unless it.

Well setting is suitable, such investment is good enough that I am happy.

I only used NORMAL's Plug, but I tried the Racing plug for the first time.
I recognized the difference from the moment I installed the Engine and attached it. It is also good and Idling is stable.
Clearly the Response was getting better.
As I actually ran, the feeling of Power increased and there was nothing wrong with it.
I will check it while using Plug life.
