Where you having any redlining issues or getting past 12k rpms before removing this part? I’m having that issue and I am trying to trace it down.

We do give a shit. We'll done. On mine, I'd bought a plug-in thing to turn off the light. No cutting for me.

Hi, did you used ones from 600?

Where did you get velocity stacks

I see you made a video and not answering a damn soul but would like too known where did you find them..

K8 with Olson mid pipe and M4 gp 133@wheel hp and 57 torque. I am going to send the motor out next winter, Yoshi cams, port and polish, ceramic coated valve’s. I am gonna have one sick 750! Stay safe fella’z

OMG. This is where people who know absolutely nothing, get their stupid ideas from. I have finally seen it for myself.....

This is why I’ll never buy a used bike ! o.O

Thought I would see a dyno test xD.... not the sound test xD

154 on my 2004 R1. Bad Dyno day and shit gas (long group ride, had nothing else to use) Nothing to it but a straight pipe.... Even had a nasty extension on it. Looking to get vstacks and ECU flash Would imagine you should have a lot more, but I guess older bikes are that much lower. New bikes these days are 200 rwhp. Crazy af

What’d you come out with after the power commander

I Cant understand what u did? do u replased the clutch ? Could u link where did u buy vel stacks?

These comes stock with 149hp so I’m confused here ??

Total screw up your bike the part is there for a reason don’t cut the wire un pin it so somebody can put it back to factory typical after market exhaust trash 🗑

The uh the uh the uh god bro kick back

Mine doesn’t move at all. Hmmm

How do i k ow wbat ones to buy do they make different ones for each bike such as mine is a 03 750 gsxr . Do they make different performance stacks for them or are they al basicaly same for that bike if aftermarket

Good video

Tô com uma suzuki 750 no modo check vc pode me dá uma luz já passei o computador nela coloquei jump e tudo mas não sai

clearly you have no idea what velocity stacks really do

Thanks for posting this vid. Just did this on my K7. Removed a M4 and installed a Yoshi TRC this past week. The FI light stayed on after installing the Yoshi and it got on my nerves! This solved everything!!!

After removing the check valve, how to extinguish the check????

After removing the check valve, how to extinguish the check

после снятия обратного клапана как потушить чек ?

It's called the SET valve, (Suzuki Exhaust Tuning) not a check valve. A check valve lets your engine crankcase breathe. There is also the PAIR valve mod, which is different.

132 at the wheel nice

other crazy shit you say?

what make cowl is that?

So i tried disabling the valves today. I think it only sounds better while its idling and if im correct the "popping" backifring sounds just disappeared. I thought the backfiring would be louder but its quite the opposite. How come?

So, I actually pulled number 30 out. FI code is gone, but now the bike jitters at low RPM up to 3K ish. At full throttle, it all good tho. Anyone else had this?

Nice vid very helpful

If you want the flap completely removed then stick a drill inside the exhaust and drill the bar plate to cut it in half. That's what I did to my 03 gsxr. (Same thing).

anyone notice any other change in performance besides increased noise levels after doing this mod? cameron

hi,do i have to put 2 stell cables which connect to exhaust at 6:04.or removed them if put them back why donot we just cut off #30 please help

Whatever lmao ;-)

As an MMI student, I hear of this modification way t0o often. This have nothing to do with emissions, after-burn (always mistakenly called backfire), noise reduction noise, mid range . The exhaust control system (EXCS) is designed to give perfect back pressure at all RPM's but it mostly noticeable and at low RPM range. Disabling this makes you LOSE YOUR LOW END TORQUE. I found that my used bike had it disabled, enabled it and got my torque gains back. Disabling is not recommended unless you are putting in a full exhaust system, AND If you choose to add any modifications to your vehicle, you would need to purchase a good after market ECU like a Power Commander and have it tuned professionally; Taking it to a Dyno ..one time.. after your mods are completed, gives you useless numbers and you might as well just stick the results on your refrigerator. To anyone that STILL wants to do this, just unplug Pin #30 and it will stay open. No need to remove. Have fun and be safe everyone.

Good video bro...helped out alot....guys be sure to cut the correct wire to get rid of the F1 check light...if not its gonna annoy the shit outta ya'll. I'm in Jamaica.....gonna show this video to all ma boys! Respect Man! Good Vid

@mike DiPerna the 1999 GSXR makes 134 CRANK, this video is measuring at the REAR WHEEL

Thinking of doing this to my bike, having the F1 light come on and noticeable lack of power between 3-5000RPM in first gear makes me believe it is all connected. Also I am hearing a noise coming from the right side fairing where that servo motor (?) the Gyro is when I turn the ignition on. So All in all im thinking of removing the whole thing before taking it in to the dealership. Anyone else with advice ?

man, 132 on the back wheel is quite alright :D

nice video bro.

Sounds like it dropped in idle? Is that kust me?

9:45/////Stay off the stuff man! :)

I just unplugged the wire for the C46 SET Valve code at the ECU plug and I believe it had more power with it hooked up and with a broken actuator motor clicking away between adjustment mode and open mode. I would never unhook and pull out all the cables and the actuator. I would want the keep the option of installing a new actuator motor if broke or put back on if when I go to sell it someone says they would rather have it on so I could make it work again. DONT CUT THE # 30 Wire! Grab a pair of NEEDLE NOSE Pliers and pull the #30 wire out. Easier to be able to push the wire back in the hole then have to splice it if you ever want to use the actuator and SET valve again.

You don't have remove the entire check valve ! Just snip the 30 wire and make sure the valve is in the open position !

@mikeD.... loooool no it doesnt

And if you under stood that you are fucken dumb

whered you get the stacks

Amazing VIdeo, thanks man.. i do have the light i shall try what you have done. Will do this first gixxer website / forums/ showthread.php ?t=174828 and then yours.
