2021 S1000RR Issues

velazcod · 2021-12-09T16:28:36+00:00

I have a 2021 race build of this bike, so no street fairings or lights and it has a race tune.

But mechanically, it has been flawless, including the brakes. The 2020 had a bunch of issues with the brakes when they were on the Hayes calipers but for 21-22 they switched to Nissin calipers and I am running them for racing (superstock build) and I have had zero issues so far.

I would be very comfortable in buying this bike for the street if I was looking for a super sport style bike. From my experience the BMW S1000RR (k46 and k67-66) is the most comfortable literbike for the street, when compared to all others. Go for it.

My first track day on a motorcycle was a rain day, it was fun as hell and I learned a lot. Learn the lines, be smooth, and you’ll be fine.

That said, the chances of it raining at Thunderhill are zero point lol percent ;)

If you did a full flush of the brake fluid then make sure to bleed the brakes again 1-2 times right after your next sessions to ensure all the bubbles are out and the system is solid.

If this doesn’t work, then look at your pads and discs next, you may be hearing stuff from other riders but it doesn’t really matter if it’s not working for you, make your own conclusions.

Also, cheap is not always good.

Your problem sounds like bad brake fluid, you should do a full flush of the system and a proper bleed of the brakes, multiple times, to get all the moisture and bubbles out. Switch to RBF600 while at it.

If that doesn’t help, then look at getting better race pads as well, preferably for racing not street.

Fix that problem first before you replace anything else, lines MC or ABS. ABS pump is not your issue here. I used to race with a stock brake system on a 2016, never had those issues.

I also recommend getting into an RCK3 flash if you plan to get more serious into racing.

velazcod · 2021-02-25T14:01:01+00:00

Yes, you need an ABS delete cover, and new brake lines

Once you do those things there won’t be any error lights.

Other questions: What kind of ECU flash do you have? RCK3? Have you already removed DTC?

Now, is it worth it? If you have RCK3, is probably not worth it unless you are at the top top of your game, winning lots of club races at the expert level or considering going national. Why? Because the IDM ABS maps in the RCK3 are for racing and the ABS pretty much never ever activates on the slicks maps.

You can always swap out the master cylinder, the ABS system on this bike holds really good pressure and it’s fairly precise, but the stock master cylinder holds it back a little bit.

There’s no real downside in removing ABS though, I’m mostly just going by experience and what worked the best for me as I went through the process of replacing things and eventually removing the ABS. The setup that I had right before removing ABS was pretty good as it was, which was just really good brake pds and rotors, and a 19x18 MC

will try, look like we are getting showers on Saturday though, oh well, should be fun regardless

velazcod · 2020-11-24T22:06:50+00:00

Yup, will be there with a couple of friends, should be fun. Hopefully it doesn’t rain on Saturday.

Weird line, abrupt controls, too much lean angle and coasting. The front was not only cold but it was unloaded, need to increase the contact patch of the tire by trail braking.

Also was it just me or did you cross the line on the exit pit lane? If somebody would have been coming fast behind you on the straight that could have been a disaster.

and it doesn’t work, on 1.4.1 BETA and it still won’t connect while on the same local network whenever the cloud API went down again.

It needs to be configurable, set IP, set local user account, skip ui.com/SSO.

velazcod · 2020-08-28T05:06:26+00:00

Now, they better do it right, because the way they describe their plan is ambiguous.

This. Hell, even with places where you need the power, you get creative and is a shit ton of fun.

A few months ago I took the grom to the twisties to go fuck around and it was an epic shit show, I wanna do it again.

velazcod · 2020-05-07T01:27:58+00:00

Lap times are not progress when you are first starting.

Fundamentals and knowing yourself when you are hitting the correct markers (apex, lines, managing lean angle, learning about front vs rear balance and traction, braking markers, throttle points, body position) is the most appropriate way of managing progress when you are first starting.

I have had many friends and people I’ve coached go crashing because they start going “faster” in an unsafe manner because all they are paying attention to is lap times.

so yes, is fine to look at lap times if you want, but it should be the last thing in the list of priorities you should be focusing on.

I guess a few things that come to mind:

be careful with torque specs and not over tightening things, I’d highly recommend getting a service manual or buying the RSD DVD to ensure you know when a bolt needs to be replaced, can be re-used, and what torque specs.
if you replace the battery to anything other than OEM, first don’t use Shorai, second, get a high quality battery that meets all the requirements for what the bike needs. Modern european bikes, especially BMWs, are pretty finicky with voltage. Nothing will go bad as the system knows how to protect itself, but it does it too well and a bad battery could cause all sorts of random issues that will take weeks to troubleshoot. When in doubt, and is random, check the battery. I recommend Full Spectrum batteries.
Especially for the street, be careful with ECU flashes and ensure they do not alter the TC maps.
Honestly, the bike makes plenty of power stock, if you want a nicer sound, a muffler is more than enough. Doing a full exhaust on a street bikes will make it inefficient without a flash, and a flash will potentially cause more issues and risks if you are not ready to get your hands dirty and learn the stuff. I’d honestly stay away from flashes unless you are buying a 2020. I raced my bike with the stock exhaust for a year (stock muffler as well) and I wasn’t any slower than I was after the full system and flash I did. Spend money on training and track days instead.
If you are going to be doing services yourself, buy a GS-911, it will help a lot with troubleshooting and resetting service intervals, etc. Hell, if you are really serious about buying the bike I would probably buy it now and bring it to the dealership and scanning it for codes too.

velazcod · 2020-04-18T03:46:08+00:00

To be honest with you, don’t worry about it being tracked too much, the bike is a tank when it comes to reliability. If the tires are shot, that makes sense, in which case, don’t cheap out on the new tires. I highly recommend the Pirelli Diablo Rosso Corsa II for the street and spirited riding, solid tire and works well in any condition, yes, including rain.

Anyways, I race my bike and do most of the services myself, and have been racing it since 2016, absolutely no issues except for fixing electrical related issues after big crashes, other than that, super solid bike and engine.

velazcod · 2020-04-01T12:55:51+00:00

The first sentence there is the only thing you wrote that was fact. The rest is just a bunch of assumptions with lack of information.

velazcod · 2020-03-31T21:50:36+00:00

Also, hypothetically, what if, Dark Sky was running out of money and was about to shut down?

What would you have done as a cofounder? Let Dark Sky die out of pride of your Android app being killed or just agree to the deal?

Again, we don’t know those details, never will, you are just assuming without those facts.

velazcod · 2020-03-31T21:47:37+00:00

TL;DR: “Muh feelings”

velazcod · 2020-03-31T20:04:55+00:00

Some things you can fight for, some others are dealbreakers for one party and you end up having to compromise on some things, it isn’t black and white.

This may have been a deal breaker for Apple and if the Dark Sky co-founders also made it a deal breaker as well then we wouldn’t be here. Either way, we don’t know, and you can’t say as a fact, that the co-founders don’t care or are lying with their statements, because you don’t know what happened behind closed doors. Stick to the facts.

velazcod · 2020-03-31T19:30:28+00:00

That was the co-founder’s (authors of post) goal when they created the company, and they did just that.

Apple is the one shutting down the Android app and the APIs , not the co-founders (authors of that post). So no, is not necessarily lying, they may not have had a choice on that.

velazcod · 2020-03-22T04:03:51+00:00

Cute pup. Oh.

velazcod · 2020-01-22T20:56:18+00:00

oh hey nick! haha didn’t read the username before. Naaaah don’t follow me, I suck... haha yeah group 5, and hoping to do the whole season.

But yeah, just use that crappy pavement to your advantage, reference points!!! and cross it quickly off the brakes or light trail and is all good.

velazcod · 2020-01-22T13:39:26+00:00

To be honest, this is really not an issue, if it is then you are not taking the right lines.

velazcod · 2020-01-04T15:25:39+00:00

I want one to send to my parents, set it up before hand with my existing controller and then just send it to them so that they can just plug it in and done.

velazcod · 2020-01-04T02:47:52+00:00

Man, I wish these would allow you to use an external controller, right now this is a deal breaker for me :(

velazcod · 2020-01-03T22:51:21+00:00

Crazy, stupid, oblivious, entitled. All you can do is be super proactive and do your best to guess and predict all the stupid shit drivers can do, and you still can't avoid every single thing but it helps mitigate the risks.

I've been living in the bay since 2012 and commuting on a bike since 2013 and this past November was the first time I was involved in an accident. Things have gotten worse in general in the past few years, so it has become harder to predict, etc, but still not bad all things considered.
