My favorite part of that article (BMW will notify owners, and dealers will replace the connecting rod bolts free of charge.) Hahaha  | ||

Sounds like a thread lock issue | ||
| Dannybuell |
A rod bolt replacement? Are the rod bolts 1x use or is this a quality assurance issue? | ||
| Boogiman1981 |
QA issue and many rod bolts are torque to yield. apparently the #1 rod bolts are failing/coming loose. seems odd to me that only 1 pair of bolts wouldn't have been torqued correctly. maybe an oddball harmonic? | ||

If the bolts were loose enough to knock then I'd be concerned about more than just the bolts. Rod big end can sometimes go oval which require the mating surfaces to be resurfaced and then the big end hole rebored to spec. Nowadays I think most manufactures use a "cracked" cap so not sure what the repair procedure would be for those other than replace. I would think that in a knock situation you would have lost the oil wedge between the rod bearing and the crank journal so I'd be demanding new crank, rods, bolts and bearing. | ||

from what i read on the s1k boards it happens after the bikes are turned up during the 600mi service. i share the same concerns that you do. the fact the dealers are cracking open brand new engine really leaves me not feeling so good. went in to buy one and found out about the stop sale order. the R1 is looking better and better at this point. | ||

do you think they will "fix" it with same rod studs and nuts that are recalled. like h-d buell does on its "warranty" work. | ||
| Boogiman1981 |
yes they likely will as the bolts themselves from my understanding aren't the problem. those bolts from what i've read aren't breaking. the nuts are backing off. only on #1 which is why i am thinking unintended harmonics. i say that because they are putting thread locker on them. not to say that thread locker is bad and never used on rod bolts but usually it isn't | ||

it would be interesting to know whether the torque specification has changed, which would imply that the previous torque spec was inadequate. if the spec doesn't change, that might imply that someone on the line was just tightening to the wrong value. that kind of misteak has happened before. | ||
| Mako |
I just guessed that studs were stretching enough for nut to loosen. I have had a v8 running on seven with piston broken off from wrist pin (bad harmonics) and didn't find any loose rod bolts? proper torque should stretch rod studs enough that they don't (loosen). | ||
| Boogiman1981 |
both interesting things. but i doubt the #1's aren't being torqued to spec as that would just be crazy odd for 2-4 to be in spec and 1 not as normally the same tools are used for all. that's why i am thinking a harmonic. sadly it's doubtful we will ever be told what bmw found to be the root cause. | ||

What is interesting is that the recall only effects a precisely defined range of production dates for the 2012 model year. In hearing about this, the first thing that I have to ask is: "What's different about the design of the 2012 version of the bike that could cause the problem?" The bike went through several design changes for 2012. I was reading the March issue of Sport Rider, which had a feature article about the changes that were made. According to the article, the only changes to the engine were in the airbox and the exhaust -- nothing deep in the motor was reportedly changed for '12. That would mean that the motor itself remains unchanged, while there's a recall specifically limited to production for the 2012 models. Looking at the recall notice, the defect effects the 2012 model manufactured between September and April. If this were an oddball harmonic, I'd venture to guess that the defect would effect other model years as well, as the engine itself is reportedly unchanged. If the internals of the engine remain unchanged and the problem is limited to production between Sept and April, that makes me think that somebody on the line screwed something up. That's the only reason that I came up with the wrong torque idea. I was thinking that if different people on the line are performing different tasks, then one person who had the wrong setup might cause the problem if their task on the line is limited to cylinder 1. Of course, that's just idle speculation on my part. We'll probably never know the real untold story. | ||

Buells just about always had minor unannounced engine changes from year to year on the motors too. For example, the 2010 1125 motor had the announced oil sight glass, but also had new cam chain guides. | ||

just read that it was a corrosion prohibiter that created improper torque values. | ||

There are SEVERAL, speculations, Speculations...at this point. Yea, with my 1125CR problems, I decided to "upgrade".....and give the BMW a try, and this happens.! First, the BMW design has no rod bolt...nuts. Just bolts. Second, anyone using "anything" other than a "lubricant" on the rod bolts is NUTS..! One item I read was the robot(s) doing the tightening just mistorqued them. While I've read, "over" AND "under" tightening....I have yet to receive a notice on mine to tell me even close to the ACTUAL problem. Guess I'd better put the new cam and followers in my CR...! Mike | ||

"I have yet to receive a notice on mine to tell me even close to the ACTUAL problem." Don't hold your breath -- when I had a BMW that was covered by a recall, it took TWO YEARS for the recall paperwork to reach me. | ||

As the owner of an 1125R and a BMW S1000RR (but not with the conrod bolt issue) I can appreciate the irony of the problem with the BMW conrod bolts, caused by a supplier to BMW putting anti-seize paste on the bolts. Apparently there have been four engines in 2012 WSB bikes that failed and it was traced to this problem. I bought the S1000RR rather than order the EBR bike on the premise that "once bitten twice shy" is an old proverb. Thank goodness the BMW recall does not apply to my 2011 model year bike, I thought I had enough problems with my 1125R. Must say though the BMW is one excellent bike to ride, as is my 1125R - they are just different solutions, the acceleration of the BMW is incredible but it does not go round corners like the 1125R, but then the 1125R is not as good as my 1200 Firebolt on the bends.

This recall is real, witnessed it first hand yesterday on a spirited street ride. The rider was not hurt, and he did not go down, not sure how he did not, some great riding on his part, scary as hell watching this all go down behind him through a cloud of white smoke, and dodging the oil spewing out...and yes it had to happen deep in a turn, rather than in a straight! It is not my place to share the details, but I will say this, if you have one of the 2012 S1000RR's that might fall into this recall, you must have it fixed immediately...if the dealership tells you there is no chance of the back tire locking up (as the rider was told by his), that is NOT true! | ||
| Dannybuell |
Buellmojo ~ When you spoke to the S1000RR rider was he noticeably adrenalized? | ||
| Buellmojo |
Not at all impressed, his first response after the fact was "I guess mine is one on the recall list", I thought that was funny. He did not seem to be shaken up at all, at least he hid it well if he was. | ||
| Timebandit |
"I guess mine is one on the recall list", I thought that was funny." At the risk of sounding like a jerk, I think your friend was stupid. It amazes me that there is a problem as serious as this one, that prompts a recall and puts the bikes on a DO NOT SELL order at the dealerships, yet some people continue to ride them without having them fixed. "Yeah, there's a recall for rear end lockups, but it won't happen to me..." That mindset exemplifies the state of denial that a lot of riders live in. When there's a recall problem that can cause a rear tire lockup, continuing to ride the bike is an unnecessary and foolish risk. I'm glad your friend wasn't hurt, and that he didn't take you down with him. (Message edited by timebandit on May 13, 2012) | ||

lol Blake as they say if your dumb you have to be tough ! | ||

Okay I will let him know your feelings if I happen to see him again, so helpful, "after the fact ministries", always in the crowd...  | ||

Look at it this way he gets a new engine,better then tearing a new engine apart to fix and no one got hurt. Mike | ||

when i read that story i thought to myself: "...these are two guys who don't like to play chess." | ||
| Buellmojo |
Wow you really have issues, how is this about me, why the need for confrontation? I had no idea his bike had issues prior to the ride, it did not miss a beat up to that point. This was a group of 8, me being 9, I only knew 2 of them prior to this ride, him not being one of them. I can play chess too...Next question please? |
