Today I received the 45mm tube so I assembled a new 15 mm longer velocity stack. 102mm protrusion from the front airbox wall = approximately 430mm intake tract.

I think this is the longest velocity stack possible as it is now close to the rear airbox wall.



Weather forecast for this week-end looks really nice

I tried the long horn today.

At first it seemed to work quite well with the engine starting to pull maybe 500 or 1000 RPM earlier than before... Then after a few more kilometers the bike did not pulled so well anymore 

At the end of the 80 Km ride I checked the autotune values and saw negative values everywhere   

I opened the airbox and found the horn at the bottom of it   

Maybe I underestimated the vibrations effect on the aluminum adhesive foil, it was not a good idea. 
I will have to try duct tape...

I would suggest tig welder. 

...or I have couple of those bellmouths on the way, I can send you one.

I know nobody able to tig weld

YES  You can PM me for the details 


By the way, after having reinstalled the classic Guaire's horn I did a second 80 Km run. Engine performance was back

The horn presence definitely makes a big difference !

Yes, it does make a big difference.

Only the Ace/Derottone kit permits the use of the horn, due to relocating the filter element.

Sort of makes me wonder what the factory and other modders were thinking? Nobody else realizes this?

[Taurim]

I tried again the long air horn with duct tape today and it held up.

Longer is better ! It suits more my riding style on very small roads.
There is no huge dip around 3.5K RPM anymore and it starts to pull from 4K up to 6K RPM : perfect 

I was still able to reach the (GPS) ton during a short highway test... just !
Maybe I lost 5 kph in top speed but it'not that important.

What is important is that on small twitsy roads the GPS speed climbs up rapidly up to 135/140 kph... which is more than enough to have your driving license cancelled If you get caught. Perfect setup 

[Guaire]

Good news, Taurim!

[Taurim]

Here we go again 



No modifications related to the engine this time 

[gizzo]

What this time? New triples or bodywork?

[Arschloch]

We may soon find out what Taurim is up to. The GT won't go fat without a tank, that's sure.

[Taurim]

Nothing too radical 

Only new clip-ons and a slight redesign of the rear. I also need to check all the connexions due to a MIL light during my last ride even though it made no difference to engine performance 

[Taurim]

First step : the rear end with the relocation of the indicators and the adaptation of a shorter mudguard.
It always takes hours to do that kind of mod because nothing never lines up properly the first time 





Next step : the Tomaselli clip-ons. It will require some machining to shorten it properly and permit the installation of bar end mirrors.

[Arschloch]

Looking good! 

[Taurim]

The (hopefully) final version with Tomaselli clip-ons and modified rear (shorter aluminum mudguard and relocated indicators)







Of course nothing was simple in the installation and it took way more time than I expected 

[Arschloch]

Looking really nice. 

I've got that bellmouth made and installed it, let's see how it holds up, but I think it should have no issues, need to ride it couple of more times to say for sure. I'm not responsible for the colour.  ...only for the material spec that was available only in that colour.
