I looked a bit more on the graph and the real difference between stock and coober is quite small in 6k+. 2-3hp will not solve my problem. That it is better around 5000 is invalid for me. But good to know, thanks for the graph.

I would like to keep the cost for the upgrades adequate to the price of the bike. So Coober (or other unit) and probably KN filter is max I would like to do. The question is, if I get, for what I will pay for. The graph up there looks promising.

@Tom, where is the graph from?

In some thread here on the forum is mentioned, that even with the coober it lost some power in high rpms. I almost ordered the unit yesterday, but I want to really be sure. I made trials with db killer "out/more holes/in" on my Arrow and it is noticeable, that without DB killer or bigger holes...

Any new info about the lamp swap? Probably will think about it :-)

Hi guys, don´t want to make a new thread. Are there any real power mods for Svart 801? I have the arrow slip-on. I am thinking now about the Coober unit (the more expensive one for 449€) I probably will not do the de-cat, if it will be so much louder, no need for that. But if extra power ...

Honestly I don´t wanted to waste some other time and wait for some other parts, etc. And to solved it by reducing the max turn was easy way for 1€ costs. I like the new possition really a LOT and have some doubts, if the with the 42mm mounts wouldn´t be worse. Probably not. But this way it...

That is exactly the problem. On the end I solved it same way as it is solved on the race track bikes - I reduced the max turn of the handlebars by adding spacers to the "steering stops" on the lower clamps of the forks. Spacer in this case are "wheel balance weights". They are self adhesive and...

Thank you for the picture! A_muz_ed find the real root-cause. Holder of the handlebars are 15mm higher on the Vit than on the Svart! So not only handlerbars are different!

Sorry for the pictures guys, I have to make some. And yes, there is a problem, that screw down on the brake lever is making dents to the plastics in full turn of the handlebars. This I have to solve, but the rest - WOW! WOW! The bike is sooo great now. I can not see any difference in comfort...

Unfortunatelly I have to say, that NO :( but I can make some today

Thanks for this warning, I had that in my mind. So ... the story, which ends up with motorcycle out of order and a bottle of Zacapa rum: It looked like an easy job. The controllers (in czech we call it "houses") on each side of the the handlebar are mounted with inner metal clamps. System I...

Handlebars arrived today. I was surprised, that there are no drilled hose and from a video looks like, there are no needed. Surprise for me, would be even more easier (I hope). Keep you posted :-D

I am not able to read it so small in German language, so I don´t know, if the test was done with "dbkiller out" also. My experience is with Arrow exhaust - killer in vs killer out and the difference is noticeable. Normally with louder exhaust you at least think it is more powerful (more sound...

Vitpilen handlebars are ordered, should arrive next Wednesday. I will keep you informed.

As I wrote in the past, I took out the dbkiller out of the Arrow exhaust. Sound was better, but I had some doubts, that the bike lost some power. On the end the sound was "too much", so I drilled higher diameter of the holes in the killer (14mm instead of original 12mm and add 3 more holes). I...

Sure I will. honestly I am fighting with the handlebars almost since beginning. But Svartpilen should be - in my case - more like a everyday bike, small travelling, sometimes 2up, sometimes a bit faster, let´s say "universal bike". But on the end I ride it as a 100% sportbike, so maybe Vitpilen...

Thanks ;o) I see, that the guy has same problem as me - the clamps for levers, when you remove original mirror, are still not available. Mine are ordered since April and still not delivered. Checked today and postponed again.

THANK you Tom. Honestly I tried to find any picture for couple of day and was NOT successful :-( You are a better seeker :-D Looks great. I ordered original bars from Vit. Probably not the cheapest solution, but should work.

6800km and 3rd set of tyres. I have the bike since 04/2025, but I have more bikes and doing track racing also (not with the Pilen ofcourse :-D).
