The perfect how to video….great job show EXACTLY how all of the connections operated. Great work sir

[@ALFAVITAGA]

Thank you! I appreciate that! ✌️

[@kawikris6005]

You Sir are an absolute legend, this helped me to remove my ECU to enable the dealer who was then able to supply me the code and IMU, to then be programmed by my local dealer (saved myself £200 for cost of IMU) for my Tuono 660 - Happy days.

[@ALFAVITAGA]

I’m super glad it helped you brother! Cheers! ✌️

[@andrewdouglas4211]

Excellent. Thanks for the tip about the clamp pliers!

[@ALFAVITAGA]

Thank you! It really saves valuable time!

[@vendy4625]

Yet another quality video Mike shout out again to Ethan the camera man. Looking forward to part two

[@ALFAVITAGA]

Thank you brother! Part 2 coming up.

[@untamedride]

Great video. Very clear and easy to follow everything. If i didn't already have the dealer install mine at one of my service intervals i'd definitely be doing this upgrade myself. Also like your cable on the seat crowl, mine just came off a few weeks ago so now i'm deciding whether or not to paint or replace it. tried to wrap it myself but that didn't go too well.

[@ALFAVITAGA]

Thank you! Its a pretty easy install. I had my seat cowl fly off after my dealer didn’t secure it in place. In their defense these seat cowls are tricky to secure. They replaced it for free, but I wanted to make sure that will not happen again so the wire is an extra safety. ✌️

[@EdoardoMazzuoli]

Super Gabro! We did 99.8hp on the dyno before Laguna! Filter, air intake, head, camshaft, clutch stm, exhaust ecc ecc!

[@ALFAVITAGA]

Gabriele 🔝💯🤌🤌

[@demmyk]

Love the enthusiasm at 0:22 ! 🤓

[@ALFAVITAGA]

😂😂

[@bshaida]

Very helpful video, thank you for posting.

[@ALFAVITAGA]

Glad it was helpful! ✌️

[@daniellindeen]

Damn you are really max out that rs660 😄 a lot of mods in that bike 👌🏼

[@ALFAVITAGA]

Its really at the max of mods. But you can always find more mods to add. Next install video will be spider rear sets. ✌️

[@Playaboy5]

@@ALFAVITAGAwhat’s the dyno reading on this now?

[@tekkietekkie]

Thanks for the plier trick, ordered!

[@ALFAVITAGA]

You’re welcome! 👌

[@delleon1126]

Great detail!

[@ALFAVITAGA]

Thank you!

[@calvin2516]

Pliers ordered, thanks!

[@ALFAVITAGA]

Nice! ✌️

[@user-challbad]

ωραίο βίντεο και αναλυτικό φίλε μου…

[@ALFAVITAGA]

💪😉

[@PabloMz14]

Awesome bike!! Where did you get that seat?? 🔥🔥

[@ALFAVITAGA]

Thank you! I got it from Luimoto. They are based in Canada. They only sell the cover not the seat. ✌️

[@maxancefly]

Hey the video is cool but what is it really for? A gain in HP? Or just the bike breathes better I don't know what is velocity stacks can you explain ?

[@ALFAVITAGA]

Thank you! Velocity stacks smooth the flow of the air into the inlet tract by utilizing the conical entry shape. The conical shape creates an entry radius for the air to follow, avoiding narrow restricted air flow. Narrow entry causes loss of horsepower. They also alter the inlet tract length. By inlet tract length we refer to the distance from the head of the intake valve to the manifold including the throttle body, to the summit of the velocity stack. The easiest way to alter the inlet tract distance is the height of the velocity stack. The height of the velocity stack is crucial, as it manages the pressure wave in the inlet tract. By managing the pressure wave by distance, you have control of the power output on the rev range. In layman’s terms, if you want more power on the high rev range you shorten the height of the velocity stack and if you want more power on the low or mid-range you increase the height of the velocity stack. The reason for that is that airflow is constant, but the intake valve opening is not. Which means that for a split moment the air flow hits a wall and stops at the head of the intake valve while being forced to return back to the entry point of the velocity stack. That happens multiple times in a millisecond. The optimal power output will be to time the airflow return to the opening of the valve. That can only happen on certain RPM with a certain velocity stack height. The optimal velocity stack is the one that smoothens the power output throughout the rev range but also offers more power at the desired rev range. In the case of the Gabro stacks for the RS660, they increase power on the low and mid-range by giving a smooth power output throughout the rev range.

[@raphaelagapit4671]

I have a question did you have original map on your bike?

[@ALFAVITAGA]

I have an Upmap installed. When you buy Gabros stacks they come with a free map to download in the Upmap market.

[@2a-usa476]

You use any loctite on the gabro screws?

[@ALFAVITAGA]

I did not. The time I installed them, Gabro had not released the update about using blue loctite.

[@antoniobenavente9734]

Hi! could you tell me which is this bellypan extender?

[@ALFAVITAGA]

I have a video install and a link in the description for it here: kzbin.info/www/bejne/r6akg6xna9Wmqqssi=uqEzzABMmbtG05NI

[@hyeGUY25]

Hey bro I've always wondered where you're originally from? I hear a slight accent and see you ride Kilometers vs mph

[@ALFAVITAGA]

I’m from Greece ✌️

[@OtherPeoplesMoneyy]

What is this upgrade going to do?

[@ALFAVITAGA]

By raising the velocity stacks higher it increases the power on low and mid range. It also comes with a free map for the Upmap. In combination with the map, it increases the power throughout the rev range but mostly on the mids. Gabro just developed variable stacks for the RS660, which will give more power throughout the rev range.

[@Chandlerd17]

Sooo i guess that’s the process to change your air filter?

[@ALFAVITAGA]

Thats the same process to access the air filter.

[@user-gh2td7tf1f]

How more horsepower?

[@ALFAVITAGA]

Velocity stacks basically move power around the rev range. It’s not so much about horsepower. In my case they increased power delivery on low and mid range. I will upload a ride review with them.

[@FONSI.G.]

7´6 me parece

[@agriculturehellas]

Δύο φορές το αγόρασες ρε με τόσα extra hahahah

[@ALFAVITAGA]

Στη κυριολεξία δύο φορές 😂

[@pantag2]

Ohh ellinas eisai? To gas tank eprepe na einai adio gia to installation? Pos k de vgike fuel?

[@ALFAVITAGA]

Κανονικά! Όχι δεν χρειάζεται να είναι άδειο. Πρέπει να έχει πιστεύω ηλεκτρονική βαλβίδα στη τρόμπα καυσίμου που ανοίγει μόνο όταν ανοίγεις το διακόπτη. ✌️

[@TimStJohn-xp8rv]

Have you seen the cost of the upgraded airbox🤦🤦🤦

[@ALFAVITAGA]

Yes, I felt the pain lol

[@GruseligerZigeuner]

Nice tools 😂

[@ALFAVITAGA]

Thanks ✌️
