Guys, it seems that my K9 has blown the crankshaft with only 5600 miles on it, the bike is 2011 and it is no longer under warranty.


See the sequence of what happened:


1 - Bike was running around 140 mph;
2 - Engine started to vibrate like a mono-cylinder engine;
3 - I saw the temp on the panel increasing from 181 F to 194 F;
4 - Engine started to lose power;
5 - Engine stalled.

No oil leaking and no smoke at all.


Everything above happened in less than 10 seconds, I didn't even have time to think about anything.


Then I parked the bike on the road and tried to start the engine again... the engine didn't even turn.


I Took the bike to the dealer and he found the battery was not being charged, so he swapped the battery and the engine started apparently with no issues, however when he pumps the throttle a little noise comes from the engine and we feel the engine vibrating.


The dealer has not opened the engine yet, but since the battery was not charging we are thinking that the crankshaft is broken at the stator side.


I have read other people complaining about crankshaft issues on K9, see below:


http://forums.13x.com/showthread.php?t=268915



My question is if the problem is really the K9 crankshaft, even if I get it replaced by another K9 crankshaft, the problem still can happen again. So does anybody know if I can replace the K9 crankshaft with the L2 crankshaft (which seems to have the root cause of the problem fixed)? Did anyone have a similar issue?

Their PN's are similar, but not the same:

12000-47850 K9 Crankshaft
12000-47860 L2 Crankshaft

I think there was oiling issue with those years causing the crankshaft to fail. I saw something about this on the forum here. Try a search and I'm sure you will come up with some info.

Is there an updated part # for the k9 crank? Or no? If there is a new part number then that should be the fix... But it may have also been a recalled problem and therefore covered? I can't see Suzuki turning their back on that..

Yeap, I also heard that the L2 crankshaft was redesigned for better oiling flow, so that's why I was wondering if I can replace the K9 crankshaft with L2 crank, but I'm not sure if it will fit properly on K9 engine or even if I would have to get more parts replaced as well.

No, there is no updated part # for the k9 crank.

This is what Suzuki said about the crank issue:

source:
http://www.edrperformance.com/insider/showthread.php?t=3924

"These accusations are completely baseless. Suzuki has always made reliability, durability, and performance
their top engineering objectives. Minor issues can develop on even the best race bikes, but
the crankshaft of every Suzuki GSXR must pass a rigorous quality control process guaranteeing longevity
and performance. Take it from me, you can count on the Suzuki GSXR 1000 to get the job done"

Time to dig into the motor as right now you're just speculating about what has gone wrong. At a minimum, pull the generator cover and see if the rotor can be moved in strange directions.

Here's a crank related thread. Note Mike Edwards' post.

I haven't heard back from the dealer as of yet but as soon as I have news I will post here.

I saw Mike Edward's post... honestly I didn't believe on this thing till it happened to me... lol :banghead

Hey guys... I'm back!!

The dealer took the stator cover off and we found the flywheel + stator + case cover totally destroyed. The crankshaft side where the flywheel was attached seems to be damaged as well... but not sure if this can be recovered (?).

See the pictures:

Does anyone would have any idea about what could have happened ? I mean... the "root cause" ?

wty or no wty I would be suing Suzuki.. Rotor came loose ?
I will ask my mechanic tomorrow but I think the rotor came loose due to a screw loose... still need to confirm though.

Suzuki deserved to be sued for this... but here in Brazil this may take years and the bike needs to stay there and untouched during the whole process.

I can't believe I will have to replace the whole crankshaft just because of this f*cking issue....

See WHAT IS THE PROBLEM here. It sounds like this may have progressed to K9's like your bike. Has the engine ever been apart prior to this?

Where in Brazil are you?

I got distracted and messed up the above link. It's now fixed.

Never been in Brazil. I've been interested in a VAZ titanium rear sprocket for some time and have been looking for someone in the vicinity of Jundiai who could interface with them. You seem to be too far away.

Thanks for the link... I can't tell for sure now but I think my bike had the same problem. I don't think it was something specific related to the recall but maybe a failure on tightening the rotor bolt when my particular bike was being assembled.

Regarding the VAZ sprocket, if you need my help just let me know... I live a bit far away from Jundiai city but I can interface with them over the phone or email if you need.

Thanks Travis !!!

ronayers.com seems to be the best option.

I'm doing a quote for the parts that I will need to replace...

Just for a comparison... the crankshaft in US is $ 900,00 - Here in brazil the same part you will pay ~ US$ 3000,00 or R$ 6600,00 but since we receive in REAIS and NOT in dollars the real price of a crankshaft here would be US$ 6600,00. (50% the price of a brand new GSXR in US).

Crazy huh ?
