Kawasaki Zx4rr. O2 delete, evap delete and pair valve delete 

This guy knows what he's talking about! Thanks for sharing knowledge, I wish you lived close to CO

Loved the video! Got a heptaforce installed and waiting for ECU appointment. Helped me figure out what else I needed to do. Hope you’re doing okay after the wreck!

So, the pair valve only works when the throttle is fully turned off, which means it won't affect the AF ratio while rolling the throttle in any degree except 0%? Preaparing for dyno test and ECU flash recently, wondering is there a need to disable pair valves temporarily while testing AF ratio. Thanks!

I know you mentioned not to block off the air system unless you use a full system without cats? Would you block it if you are using just the Graves slip on?

hi, is it necessary to remove the canister? Or can I just install the block off plates?

I got velocity stacks, full system exhaust, emission block off cap, hi flow air filter. Should I remove my evap? Does it change anything if I take it off or leave it on?

Very informative, thanks!

What if you do just a slip and flash. Do you need to cap the ports and remove the smog pump?

What did you do with the electrical connector to the purge valve? Bypassed it with a resistor?

With that air going into the exhaust, is there any effect on engine braking stock vs aftermarket system and block off plates installed?

Question for you. I ordered the Yoshi Hepta Force exhaust and am wanting to keep this otherwise as stock as possible. Is there an issue if I just extend the O2 sensor and don’t do a flash? I’m not overly concerned about more performance, I just wanted a bit more sound and a lower profile mounted exhaust. Also not wanting to risk voiding any of my warranties.

Curious about that fuel mileage tracking on your mt10 David. Last time I bothered to check I got 25mpg almost exactly. That's doing hard pulls repeatedly. I'm always at the gas station but well worth it. By the way, we did have that yosh slip-on on the wrong side of mounting bracket. Holy cow is that thing loud w/o baffle, was pissing people off!😂 Looks tucked in and pretty normal now.👍 Thanks David!

If I remove the solenoid on the pair valves but not unplug it will it still throw a code ? Like just undo it and move it out of the way

Have you done a dyno with the Yoshimura R77s?

Did you weigh the bike stock? I assume it's close to advertised curb weight anyway. But it would be cool to see how much weight you end up saving once you get it in full race trim!

Can you do a video on removing the 4RR tank? Also, can't find your ECU removal video??

Nice

Good start removing useless stuff and bringing weight down 😊
