I've been riding between 6000 and 14000 feet. I've been from Denver to Mt Evans to Glenwood springs, Cortez, Salida and now I'm in whatever city the fiddler ampitheatre is so I've been everywhere.

Or I was also looking into maybe bringing it to a dyno.

The highest octane I can get in my home town is around 93. The closest station that sells "race fuel" 100+ octane is 30 minutes away.

I'm planning on doing the ecu reset when I get home just to be sure. I wanted to do it here but my tools are back at my buddy's in Denver. We didn't have any room in the packs.

I didn't know there was such a massive difference in rwhp from the spec sheet. Unless the I think it was 189 on the spec sheet is hp at the crank.
Yes, 189hp is HP at the crank, but understand that the North American and certain Asian markets have baked in Electronic Throttle Valve restrictions - as in the throttle body butterfly valves will close from 100% open at 9000rpm to 72% by 10500rpm and then that restriction is carried all the way to the rev limit.

So stock right out of the crate no North American 2017+ CBR1K is ever going to produce even 189hp at the crank - couple this throttle restriction with 30% intake tube restriction and your altitude - who knows, maybe your bike is only putting 125rwhp to the ground. I kid... but you get the picture? LOL

You may get some of that back by tuning (only tune the ECU with Woolich!), a full exhaust and removing the intake tube restrictions, but you are still going to be at altitude.

And what is this ECU reset everyone keeps referring to? These bikes are not storing long term fuel trims so I am not sure what woudl need to be reset?

I'll have to see about removing the 30% restriction of airflow on the intake tubes. I'm debating on picking up a Woolich system next year. Also I'm just in high altitude at the moment I live in Michigan, I believe my city is only 600 feet above sea level so the loss of power is negligible back home.

That's why I want to test the launch back home instead of here before responding to how it reacted. Since I've been here I noticed the loss of power greatly, my brother also has on his bike also.

Sending the ECU to someone like Dano at @Danos Performance and having him do a Woolich tune based upon your mods is far cheaper than the whole Woolich system, if that works for you.

I was actually just looking at danos seems to do some good work the Woolwich system doesn't seem to bad. Like 500 for the kit. I'm looking at dropping a grand minimum into the bike next riding season so Ill probably just grab the kit. I'd like to setup a few different profiles any how since I do commute in the bike also. It would be nice to learn how to tune since I haven't really done any of this.
@RC45 I seen you post in another thread a awhile ago that tuning is pretty pointless without a full system and getting a new air intake since you said removing the restrictor plugs isn't enough due to the resonators in the air intake. I tried to find the tenkates air intake but couldn't find it anywhere. Also seen someone saying that if you swap to that intake you need to make modifications to the fairing is this correct?

Appreciate all you guys and the information you are providing me thank you!

Yea, I was the one who made that initial post about removing the inserts the US version has in the ducts (so lame they did that in the first place). I had picked up a set of the Ten Kate motocarbon ducts, but there are no mounting points to mate it up to stock fairings, turns out they are ment to be used with the motocarbon fairing set. Theirs mate straight from airbox and slide into the intake port whereas ours use those resonators as mounting locations and just rest flush with the intake area. So I ended up selling them off for now in hopes that down the road someone will make a set ment to mount up to stock fairings, but haven't come across anything yet. If you do want to try modifying a set you can just go to the tenkateracingproducts website and you'll find them there.

I've had a 2006 cbr1000rr since 2014, it definitely took off from 0 to 35mph faster then my 2017 cbr1000rr abs. I think it's just the traction control doing that. I really dont like the feel of the abs brakes. I would like to remove the system if any of you guys have a write up on how to do that, that would be awesome. I was also wondering if you know if a 2012 to 2016 rim would fit the 2017 cbr? They look the same and the speed pulsar ring seems to mount up to the rotor not the rim. I would really like to purchase an extra set of rims for this bike to have slicks ready to go for track days. Please let me know if you guys know about these things.

Which bike do youhave? ABS, SP1 or SP2?

What is your altitude, and what power setting you using? TC setting?
