So, has the rectifier recall solved the problem? Mine 750 08 has the same problem :( ... I guess I'll have to change O2 sensor...
Thanks for this thread!
me and laracroft had exhanged our o2 sensor, no more problem on her bike, and mine still run great, the difference between our bikes, i dont have the cat, so i think the o2 doesnt come as hot as it was on her bike and maybe the problem starts at a certain temperature and get false reading.

Is anyone else located in Canada for this issue? I'm trying to help the dealer that has my motorcycle. I took mine to Wheelsports In Orleans Ontario. Where did you get your motorcycle serviced for this issue in Canada?

had same problem with my 08 600 . ended up being the fuel pump , also there is a recall for your bike on the rectifier. Make sure they replace it or your bike will keep dying on u , its happening to me now at 2700 miles, ill take it in tomorrow.

Similar issues with my k9 750. The difference being I do not get any significant power loss with a surge, instead mine between 4500-6500 in 3-6 gear constant throttle, stumbles and bobbles to the point that once it felt like the damn back tire was wobbling from side to side. ( it wasn't) Just had the o2 sensor replaced and no difference, checked the tps and it says it is good. Rectifier was replaced months ago. Have over 10,000 miles and it has only been doing this for the last 1000-1500. Any one with any other suggestions?

Just want to go ahead and tell everyone the EXACT problem with their bikes. I recently bought my 08 gsxr 600 and had problems so I did some digging. Come to find out, Suzuki posted a bulletin (201) in 2009 stating that the O2 sensor needed replaced. I recently did myself one better, just installed an O2 sensor eliminator and presto! no more power loss and she runs like a champ!! Best $30 fix ever. You can find them here on ebay- http://www.ebay.com/itm/Oxygen-o2-sensor-eliminator-Suzuki-GSXR-600-K8-K9-K10-/260726040862?pt=UK_Motorcycle_Parts&hash=item3cb47ba91e#ht_1019wt_1123

Try removing the SET valve from your exhaust, you can leave the valve itself but remove the cables and control unit, there's a writeup on here somewhere. This fixed the problem for me

They replaced the O2 under warranty and it fixed the problem. I went back to the O2 eliminator from ebay. This product has make my motorcycle better. I highly recommend the O2 eliminator.

Second that. Put an O2 eliminator in after umming and aahing for ages. Wow it has made my bike feel new again. Good ol Suzuki making crap sensors again.

having this exact same problem with my K9, just bought it 2nd hand... shit.
Driving around town, or motorway at a consistent <6k rpm whether 3rd or 6th gear and it just feels like it is running out of gas (done it many times :facepalm:) then you have to give it a decent twist to get the power back, at least im still getting used to it in C mode so its not too much of a kick when it comes back. Will talk to a dealer tomorrow, only got to Page 2 so will carry on to find fix.
At 12000km atm, am sure the previous owner must have noticed this before he sold it but meh, its my problem now.

*Edit* So have finally got to the solution, page 9? the o2 sensor. Anyone know the approximate value of one of these?
And has anyone outside of the states been able to get the warranty mentioned in page 16?

*Edit 2*
So I went into a suzuki dealer today on a work break and told them all about it. They blamed the exhaust kit interfering with the sensors with airflow and *insert techhy jargon here* and said I needed a Dyno tune and ECU remap or some shit at the cost of about a grand (am pretty sure this has already been done by the previous owner when they installed kit.) . I said no thanks. I think Ill just deal with it, the problem isn't worth a grand to me.

I'm at my wit's fucking end with this thing in 3rd gear and up. The powerband starting at around ~5k is absolutely unusable. I was in a pretty lean earlier on a tight turn, 4th gear, ~7k RPM, 70MPH or so, and all power cut loose. Terrifying.

Brand new O2 sensor, rectifier recall done, kickstand sensor checked and rechecked. I love my bike but I am very close to selling and getting far, far away from the 08-10 600s and 750s. 3rd and 4th gears are NOT useable above 5K RPM. God this is so frustrating. :(
