O2 modifier - VERY HAPPY

Where do you get a GREEN filter.

Velocity stacks help airflow and can be used to tune the torque curve of the motor. Velocity stacks are very important when working with carbs. With carbs there is fuel stand off caused by positive pressure pulse pushing air and fuel back out of the carb. With out velocity stacks that fuel could be lost. The stacks help capture this fuel when the negative pulse pulls air back into the motor. Without stacks or an air cleaner this fuel can be lost and create a lean condition. Short stacks raise torque peak long stacks lower the torque peak. Just as short pipes allow the motor to rev faster and have the torque peak at a higher rpm. Longer pipes rev slower and have peak torque at a lower rpm. With fuel injection the fuel stand off is removed from equasion, although the pressure pulses are still present controling torque. That said I removed half of the stacks in my wifes stock air box because the distance between the top of the box and top of the stacks was only about 1/2 inch. The air had to turn 90 degrees in that close space not condusive to good air flow. I also removed the rubber silencers. She now needs a JBPRO. She does have an O2 mod and can feel the difference. I have the Kewlmetal intake and JBPRO and love it, with the short or no stacks it revs fantastic.

Forgot to mention she has K+N filter.

Make that a Ditto for me!!! Glenn as Big Bird

I just put mine on today... Ditto for me too....

Installed my O2 mod today, what a difference, no more popping, pulls better, like a different bike .....

[Motavar]

Mine should be arriving shortly. I'm jealous of you guys !

Is it easy to install?

Super Easy install ... the only issue I had was removing the old sensor from the pipe ... nothing that a little W-D 40 couldn't resolve to make turning it much easier ... be sure to disconnect the O2 sensor and snake the wire down before you attempt to remove the actual sensor as there is the possibility to twist the wire off of the sensor when removing it.

It will come soon enough ...you just need to make sure you are good and healed up from your accident ... glad to know you will be ryding again soon

I have a 2008 GS SM5 with the Hindle pipe and would like to get the O2 modifier. Where can I get one now in 2015?

Tried the Power Commander with the Optimizer with a free flow exhaust. Saw no power difference at all and now my O2 sensors are showing bad. Removed the Power Commander crap and taking to shop to spend even more to fix the experiment-----------never again!

Have you talked to the manufacturer? Others have had good results from this setup.

This is why I'm a huge fan of checking AFR vs. Bolting on and relying on an auto tune program.
The PCV can be a great tool if used properly. However, like most performance add ons, can cause a lot of grief too.
Best of luck!

AFR - After Fail Response?

Might as well be....[emoji19]

Ditto !!! Where!?!?

And/or ... would a Wind Band o2 sensor or replacing it with an NGK ntk sensor be the same? (replacing the oem one = better results)

Thanks!
