801 owners club

Two graphs I found; they're from a Duke 890 with the Coober-Box; the results with the FuelX should be about the same.
The AFR is near 13,2; with a "good" (not too small) muffler some power gain between 5000 and 8000 rpm seems to be possible.

I’m pretty sure that is the airbox from Coober. Big job to get that installed.

That was a little too much work for my taste. Had to remove the right side of the tank, the side fairing for the airbox and two side panels on top of the engine. Everything works great now but some wires are touching the top of the engine so I’ll have to remove everything again and tighten that up.

The graphs are with the Coober lambda sensor manager installed.

Yes, but they haven’t updated the website yet. The Coober LM also only connects to the two lambda sensors on the pipes, not the one on the cat.

Just noticed; it seems the current EURO5+ Coober LM is also connected to the third sensor (the Oxygen sensor) behind the cat.

Interesting! I didn’t get any warning faults after test running it on idle for ten minutes. We’ll see what happens.

Maybe it's just needed if you want to de-cat the bike.

That was my guess. I won’t be doing that, the bike is loud enough and there’s no “stock” full system map available anyway.

I’m gonna have to re-do it again since there are wires too close to the top of the engine. I’ll try making a video of it since I appreciate other people doing install vids.

Today I did another 300km daytrip on small twisty roads / lots of them are very bumpy with bad tarmac.
This time with the optional "Ergo rider's seat".
I was quite sceptical, but It's definitely better than the stock seat!!

The Ergo you used...was it the one that is 25 mm taller? If so did you notice the difference in riding posture?
Thanks.

It's the standard height; same like the stock seat.

Maybe interesting to you; if you want to add some more air to the system.
The 801 and the Duke 790 airbox-covers are identical / part-number C90706002000.
So most likely the Coober Duke 790 airbox-cover will also fit the 801.

I made a video.


And installed some wind protection for the hands.

 

[Tom]

The video is great!

But you do definitely need some handguards made from forged carbon!

 

[yonsson]

I don’t know if I like or dislike the look with hand guards but they seem to work when it comes to stopping the cold winds.

Hi, I'm wondering know where did you get those rear foot pegs cover, is that share with 790/890?

I haven’t done anything to the foot pegs so I don’t know if it’s a shared part.

uhm...I mean this one, you removed the backseat foot pegs, where did you get that?

Correct. The Duke has different measurements, so a Duke hanger won’t fit.

 

[riz]

OK, I see. So that means the other side has nothing but two holes, right? Gonna find something to cover it. THX

The two short screws and the two washers will cover the holes on the left side; they are included in the kit.
