I'm done with the engine performance mods for now. I am kind of pissed. I would rather work on a weight reduction. It is a much more straightforward and rewarding process. At very least you know before the installation if you are fooled or not.
Here are the component I used in my venture for a more power:
1. Double Dog exhaust:
From Double Dog web site:
In an otherwise stock StreetFighter, the 134DD adds over 10bhp at 6,000rpm compared to the Termi race system (which is likewise stronger than the stock exhaust system). See the dyno charts for the strong torque and horsepower gains through the midrange, converging with the Termi horsepower at peak.
You will feel that kind of power/torque gain on the 'butt dyno' immediately....
2. EVR Airbox
Interchangeable with the original model without changes and volumetric capacity greater than the original model.
Carbon fiber made, worked in autoclave, it provides a significant increase of the performances above all from medium to maximum rpm.

3. DM Meccanica Velocity Stacks
Velocity stack length, taper and radius characteristics are essential for maximum performance. DM Meccanica collaborated with some of the most famous Ducati teams and setup technicians to develop
a velocity stack which increases performance on both standard factory and developed engines of the Ducati 1098 (all models besides the 1098R).
The bike was making 143 HP with a full Termi system and DP large air intakes.
Since Double Dog stated on their web site that there are additional 10 HPs over the full Termi exhaust system I was expecting to get somewhere close to 153 HP from the DD alone (previous 143 plus additional 10 from DD = 153 - see their Dyno chart).
And since aside from DDog exhaust the bike had received EVR airbox and velocity stacks I was hoping to get really close to 160. I am not the mechanic or the bike developer. I am the end user. I read the info supplied by the manufacturer. I study the Dyno charts they post. There is no fucking way to verify if it is true or not till you install the performance part and test the bike on Dyno. When I drop the bike at the mechanic shop I want to do as much work as possible withing one session. I don't want to install the airbox first, run Dyno, remove the airbox - install the velocity stacks, run Dyno, uninstall the velocity stack - install the exhaust, run Dyno. Now with the airbox and exhaust, another Dyno. Now with the exhaust and velocity stacks, run Dyno. That is too much of testing activity for a guy like me. And the after market manufacturers realize it too. So, don't get surprise to get no or even less performance from the mods you make.
With the weight saving everything is much simpler. You just put the thing on a scale to see the result. That simple.
By the way, do you really believe you will be able to extract the 200 HPs out of Streetfighter's 1098 engine? I've thought a "200 HP" term belongs to MotoGP and maybe to Desmosedici RR. Streetfighter with its stock engine/suspension (again) components by my quite old opinion is not even suitable for a such challenge. Just leave it as is. And enjoy riding a hooligan. If you want a Super Power start with Desmosedici. And modify that beast to the level you want. That would make way more sense.
I would modify the suspension first. The hands and feet controls - second. Reduce the bike and maybe your own body weight to its absolute minimum - that is a third (the most meaningful upgrade performed on a bike without a need to have a team of mechanics and developers working on you engine). And then as a very last one, and the most mysterious one - the engine upgrades. You soon will find that Streetfighter motor has the least amount of performance parts developed for racing. Monster has more. 1098 has a ton. There are few choices even for Hyper motor...

.. However it would be a bastard to ride fast. It was hard to keep the front end on the ground under hard accelleration in stock form but with 200hp it would be nearly a mission impossible but most likely extremely fun too.
