    '04 R6 running problems

    Hi guys. I went for a ride on my recently purchased R6 yesterday. Did the Akaroa G.P and it performed beautifully for almost the entire run. As I got back into town it started running as though it was starving for fuel, possibly missing. It was just running rough. It lacked power in the lower rev bracket. I got it home and it didn't want to start this morning so I checked today: Air filter ok. Fuel pump primes ok but the screen mesh had a bit of crap on it so I cleaned that off. Spark plugs weren't looking too flash so I have replaced them. It still doesn't want to start. It almost does but then dies. The battery is now currently charging after dropping down to 11.96V.

    Bike has only done 9000k's and is very tidy. I'm not sure if it's had the TPS replaced, I understand there was a recall for this year. Could that be it? I'm going to have to take it to Trevor Pierce (I'm in Christchurch), I usually go to Kevin at KG's but thats with carby bikes and not sure if he'll work on this type being fuel injected. I find him to be very good what's peoples experiences of Trevor Pierce? Or any recommendations for a good trust worthy technician that know's Yamaha R6 really well? I don't want parts thrown at it type diagnosis. I could do that... Other thoughts are Crank Sensor? Coils? I can test coils once battery is recharged and I was also going to bring up the fault codes to see if any.

    Any helpful advice would be appreciated especially in where to take it... I'm gutted I've only had the bike a week...

    acess the dianostic setup and write all the codes down.
    so far you have covered your bases.

    R1's and R6's do not like flat or batteries with dead cells

    Hey thanks for the info on the battery, carburetor. Good to know for the future. The battery is healthy it had just lost voltage from cranking the starter over the day (I'd crank a few goes then let it rest...). Fully charged now I rang T.P. today and they will be picking my bike up tomorrow. I was looking at doing as much myself because I wasn't sure how I was going to get it into them as it wasn't running and I work long hours and it Easter this weekend blah blah blah. Happy to hear they do pick ups. Whatever they find out I will pass along on this thread for anyone else who has a problem. Hopefully it may help, and this isn't going to be too costly.

    Not quite the same thing but my fzr did something similar when the battery I had was getting on slightly, almost start then not, also ran rough with that too - trevor pierce have been pretty good to deal with in my view, a little on the pricey side for some stuff though.

    update

    Hi everyone I just thought I'd share what the story is with my R6. Basically it was the plugs were fouled to buggery. The reason it wouldn't start is because I'd put on O-ring type seal around the wrong way when I'd put the fuel pump back together. Gutted!! So I'd actually fixed the running like shit problem (spark plugs)but created another. Dork yes I am.

    Anyhoo it is running sweet now with Trevor yet to do a test run tomorrow to make sure. So for future reference always check ya plugs first!! Also the plugs NGK CR10EK are too cold for our fuel I had replaced them with the CR9EK which I am told are ideal for the type of riding most will do. I.e. daily commute and fun runs. I was surprised the plugs were so badly fouled but Trevor knows the bike (only done less than 10000k) and has informed me of the amount of running on the choke circuit only whilst it was between owners. i.e people come hear it running thats it, don't ride it etc blahblah. So anyway I'm stoked.

    I would recommend Trevor, it's the first time I have used him he seems very friendly and happy to listen to you. I was quite stressed as I had outlayed a fair sum to buy the bike and then bang a week after procurement it's in the shop. A couple of less than sufficient sleepless nights did ensue and I am generally not a worrier type of guy, and he seemed to just take all that in his stride.

    I hope this will help any one in the future feel free to ask questions and I will elaborate where I can.

    biggest thing i have found with the r1 and r6 injected models ( and trick trumpets )
    fire up the bike let it warm up and change program's
    do not be afraid to give the bike decent rev's through the range to keep the
    plugs clean ( though watch the speedo ) otherwise neat machines..
