Since my R6 (03) has come out for the "summer" it's been misfiring, quite dramatically.
I usually leave it running on the stand for a while as i get my gear on so it starts warming up, pootle about on it keeping the revs low until it gets up to 70(ish)C, then start to open it up a bit - at about 8k rpm it starts to misfire - bunnyhopping down the road. If i pull over at this point and try to hold the throttle at 8krpm, it'll go back and forth between about 8 and 6k rpm. After a bit of abuse it seems to clear and run better although not entirely gone for the rest of the trip.
I spent Sunday replacing the plugs and checking the coil impedence and it still persists...
Any sugestions before i take it to a dealer (sticking valve / injector / sensor)??

Well just incase anyone cares - repair shop found the problem - kink in the fuel return hose on the injector rail.
Of course we care....I've got absolutely no idea what a return hose oran injector rail is...but I'm glad it's sorted...and I trust you still only have the 1 mortgage??!!(assuming the norm etc, etc)
Ahhhhhhhhhh - you do care !
Yeah not too bad cost - £128 for 2 3/4 hours labour and sundries (what ever sundries are on straightening a hose?!?). Although there now seems to be a little chip in the (already scratched) yoke and one of the spacer washers that hold the riders seat in place was missing (they found it in the workshop and it's in the post!).
Worse than that I'm pretty sure it was them that caused the problem in the first place as they were the last people to work on it -it was serviced by them in November.

NOOOOOOOOOOOOOOOOOOO!!!!!!!!
It's back - misfiring like a bee-atch.
Rode it back from the repair shop (about 10 miles) no problems, left it since then as the weathers been rubish, then took it out over the weekend - barely ridable it even stalled twice on tick-over...
Anyone wanna buy an R6 - good (sort of) runner - honest !

Well it's been in there since last Thurday - they've just been on the phone to say they reckon it's an intermittent fuel pump - £537 +VAT for a new one, but they've found a second hand one for £245!
with about another £200 worth of labour on top of the £130 previously for finding a kink in the fuel return... ouch...!
In fairness it was quite intermittent and they have had it on the dino and all sorts!

I don't believe it!!!!
managed about 100 miles with no problems - I thought the fuel pump had fixed it as they promised, but it's back playing silly boogers tonight....
Now, do i chuck it back at the repair shop and demand my money back, as i have paid nearly £600 for them to make my bike misfire somewhat less, and they have but a small scratch (about 2cm long)through the paint near the seat (which they have agreed is their fault and will repair).
OR
is it reasonable that they charge me because they have spent time on it and they have replaced parts (it just didn't fix it).
And if i take it back should i pay more?

Jesus, I would take it back and tell them your not at all happy, £600 and still not fixed, no I would not pay any more. It has to be something simple, It's always the case, it sounds to me they have no idea what they are doing. It's a pity you don't live near me, as I know someone who could fix it.
I'm sure, I,m sure.
Good luck in getting it sorted.
John.
yeah, i have a feeling it's going to be something simple like a corroded connector or a bit of crap floating about in the fuel tank or something like that. I'm tempted to take it somewhere else, but the trouble is if i take it else-where the first repair shop is off the hook.
Does anyone know how the sparkplugs are driven on the 2003 R6 ??
I reaslise that each plug has its own coil mounted on it, with a low voltage lead running to it, but what creates the low voltage pulses - some sort of low voltage distributor or is it something a bit more clever?

Thats why you pay dealer top prices, so that problems will get sorted first time.
They seem to have made a bit ofd an ar5e of this.
You should start by talking to the owner of the shop and explain that your situation. They should have diagnosed and fixed this first time.
I'm assuming they are a proper Yam dealer and dont come to work with spurs on and wear 6 shooters!!
If that fails then citizens advice, or if you have al lawyer, get hime to set out your concerns in a letter to the bike shop (usually costs £25) so well worth it

I had a similar problem last year (not on an R6, but a Yamaha 750). All the symptoms suggested a fuel starvation problem. Turned out to be the crank sensor. Have they checked the crank and cam sensors? My bike would not rev over 8k, then it started cutting out on tickover. Eventually it wouldn't start. I found out that there wasn't a spark, changed ignition packs, plugs, leads, etc. Then checked the sensors and found a weak signal, put a new one in. She now runs like a dream again 
Would i find the process in a Haynes manual?I thought when an R6 stopped running, you just insert a giant key into what looks like the fuel filler hole and wind the clockwork back up?
But seriously.... I feel for ya dude.... i hate faults like that, plays on ya mind the longer it goes on until you start to think that ya bike is now worth £0
Good luck with it!
