Thx for your vidz. I was installing a new air filter and used your vid to see how to remove gas tank. Got to say, those bottom 2 tabs you said we're a pain actually was a snap...no pun intended...went from the bottom. I even used your vid installing the Yamaha heated grips. I'll be recommending your video in my post on the FZ-10 FB page I'm on, and all my other FB groups.

[@BMWsr-is2xb]

Thanks Richie. One small tip another video made to address the hole left in the bottom of the air scoop. Was to cut off the grey plastic "nipple" that held the AIS system in place and use it as a plug. Just a small point Otherwise awesome video!

[@seancarroll8326]

@@RichieIsf Just seeing your year old reply now as I am re watching this video to refresh myself. I am finally installing the resistor to take away the check engine light. My kit didn't include it, I guess I was supposed to leave the AIS dangling inside but I thought my ECU flash would stop that code. Congrats on the baby! I just had one in October, so I know how wrenching on the bike has taken a backseat to raising a little one. I still plan on using some of the other videos you've posted to guide me through some other mods I'm considering. Looking forward to the new videos. Maybe you'll inspire me to do more mods. You definitely had me do a couple myself with your vids, without them, I would have just sent it to the shop and paid a mechanic. So, you saved me money and helped me learn. Great experience. Thanks. Quick question, I ECU flashed my bike, but as I roll on the throttle, there are some serious abrupt steps in power, will a power commander and dyno smooth that out?

[@RichieIsf]

@sean , I’d take it back to your tuner and get him to smooth the throttle out . Congrats on your baby bud , hope mum and bub are safe and well . I’ve just welcomed a baby boy to my tribe . But am going to get back to these Vids real soon .

Hi Rich, what difference if any did removing the AIS make and what about the Airbox inlet restricter/snorkel did it make a noticeable difference, or just more inlet noise ?

[@luredi]

Muy bien expicado todo el trabajo, excelente vídeo !!

[@hawthorne7712]

Hey Rich, question about the plug for the pump delete. My Graves plates didn't come with one, and with my exhaust servo delete I put a servo tricker plug in but it had a computer board off of it to tell the computer how far the valve is open according to throttle position. This is just a pump that runs one speed. So is the plug in just sending power back down to the computer to say it's on? No computer tricker module on it, so in theory could you just complete the power circuit by touching the pins together inside the female end of the plug? Does that makes sense what I'm asking? Instead of ordering the plug from smartmoto for $20 plus shipping I could just use a jumper? Thanks

[@sinaismael853]

hello my dear, thanks for the video, but a simple question... what the AIS doing in the bike?

[@robertpowers1045]

They put it on a lot of bikes...had a Yamaha 450 enduro dirt bike. My understanding is it limits air/throttle control to match the restrictive exhaust they put on bikes today...it really makes a difference in acceleration when it’s gone, mine built revs faster

[@AdryDoic]

in therms of power nothing!! with throttle close it gets air in the exhaust system to get burnt all combustion gas that was in excess with last acceleration! yes these pops and bang many people love to hear! blocking AIS you will have a Pop free ride !

[@ticoruizsuarez]

1. If you are using your motorcycle on a closed course (racing, track days, etc.) you will want to remove all unnecessary equipment from your bike for reduced weight and ease of maintenance. 2. To get an accurate Air:Fuel (A/F) ratio when dynoing the bike. The air injection system pumps fresh air directly into the exhaust stream in order to burn off any unused fuel. Unfortunately by doing this the A/F ratio is thrown off by the extra "fresh air" in the exhaust stream. By removing the air injection system you can achieve an accurate A/F ratio. 3. This addition will typically remove the majority of popping on deceleration that can be experienced with un-burnt gasses within the emission charcoal chamber. Note: Proper tuning may be needed and this is general feedback

[@kted252]

So, what performance difference did the changes make ? p.s. I have a MT10 SP with a link pipe which I think sounds good but probably makes NO difference to the performance ....!?

[@RichieIsf]

Wayne Pratt , thanks for your feedback. No “real performance “ upgrade as such. However a quick google search of the forums would suggest when u do flash tune the bike it’s much easier for your tuner to get the mixtures right, which does yield HP , also it eliminates the banging and popping on decel, which is rumored to over time cause damage to the exhaust valves. .

HI RICHIES SORRY FOR MY QUESTION FOR WHICH REASON IT 'S GOOD TO REMOVE THE AIS ? IT'S GOOD?

[@qoe75]

what gains are there from removing the AIS?

[@exuptoy]

The air injection system pumps fresh air directly into the exhaust stream in order to burn off any unused fuel. Unfortunately by doing this the A/F ratio is thrown off by the extra "fresh air" in the exhaust stream if you were trying to dyno the bike for instance. By removing the air injection system you can achieve an accurate A/F ratio. It will also reduce or stop the popping and from the exhaust on the overrun. Although some people like this!

[@yockanookany]

If y’all are having issues pulling the tubes out of the tank, just pull them up with the tank. I found that much easier. Just make sure to take them off afterwards or position the tank and tubes where it won’t leak gas.

[@RichieIsf]

Yeh, true , however if you happen to lift the tan k to high you run the risk of breaking the connector off the fuel pump. and the other hoses being completely dislodged from where they are meant to be.

[@icdeadpeopletoo]

can you please explain why you have removed the AIS and have a different MT 10 after the rim damage? now black wheels with a different registration plate

[@RichieIsf]

Thanks for your question... The rim damage/AIS bike is mine , the black bike belongs to a mate who wanted to fit a Link pipe... the fitment is the same no matter the colour of the bike .. 👍

[@exuptoy]

Nice job fella, but you don't wanna be levering out the AIS blanking plug like that! The black bar across the top of the plug is a resistor to fool the system into thinking that it is still connected! Resistors are ceramic devices which will snap in half and you will bring up the MIL light if it got damaged. Otherwise, a nice instruction video.

Are the side snorkels on the MT10 functional or just for looks?

Is there no way to remove the stock airbox without first removing those dozen screws and opening the airbox up?

[@RichieIsf]

Justin R. , thanks for your comments mate 👍, sadly no you will need to remove the dozen screws to remove the lid of the air box as the bottom of the box is held to the engine at your throttle bodies by 6 Allen bolts either side of the intake trumpets.

[@mprziv]

Gotcha. That's what it looked like in the video, appreciate the response!

[@kindajal]

awesome

[@icdeadpeopletoo]

so why have you removed the AIS?

[@RichieIsf]

When you install the Decat pipe , the bike will bang and pop on decal , the AIS allows air into the exhaust and causes the engine to run lean , causing the banging and popping, which if left will cause damage to the Exhaust valves, Plus if tuning the bike (woolich ) you can turn the AIS off. The weight of the standard Cat is amazing , easily 4-5 kgs, not to mention how much easier your bike will accelerate .

[@bigflave2947]

Sprint filter is better. And no heard you should take out that rubber scoop too. Your bike will get way better air flow.

[@porkchopspapi5757]

So the relevant question: how much performance increase does this significant operation produce?

[@ticoruizsuarez]

A lot, makes it easy for computer reading on the air fuel ratio
