Explain this, then.

Could also be a slightly clogged fuel pump/injector.

The thrashing cleared it possibly?

I was thinking the same Dave!

We won't know now unless the problem returns, Which I hope it doesn't
Owl!!
Good Luck Owl, I hate hearing about problems with these bikes I start to feel like I ate a $hit sandwich that I bought one!!!

 

[owl]

Tom, do you get your fuel from the same place? :?

No - get it from wherever I am at the time - supermarket, major outlet, UK, France, wherever.

I will wait & see what happens with the bike over the next 2 weeks - will be going up to Cleveland (wherever that is) at the weekend on the UK Northern Rocket Run. See how the old girl performs in the Northern wastelands of this fair country.

I wouldn't worry too much dw - this is the only problem I've had in 12000 miles, and I regard it as just a blip.

Perhaps the moral of the story is, if it plays up, ride it like you stole it for a couple of hundred miles.

Be a great excuse if you're caught :lol:

A few years ago I bought a car that had been owned by an old guy who had only ever used it for commuting around town. He'd had it from new so the car had never ever been anything like thrashed.

The first time I took it down the motorway for a spirited drive it caught fire :shock: I noticed flames in the rear view mirror, pulled onto the hard shoulder and ran away from the car thinking it was going up in smoke The smoke died down after a couple of minutes. When I restarted the car there were huge clouds of smoke coming out of the exhaust for a few seconds then it ran fine.

If there was something clogged I'm pretty certain that un-clogged it It certainly ran fine for the next couple of years.

You saying I ride like a duffer?

I think you should run the S**T out of that Rocket every once in a while !!

I believe that with the ECU getting signals from all kinds of sensors and if one of them are out of whack say like the primary throttle sensor (TPS) then the engine can get confused on its Engine Management Adaptation routine which the system adapts even for the changing riding behavior. page 11.133 under general info top right if the TPS sticks/doesn't return to the last set parameter and sends a different signal to the ECU and lord knows what else and the adaption bounces around adapting as much as possible you will see some erratic behavior I bet!!!!!
Think about it if the closed throttle position changes I would imagine idle speed control is affected, Oxygen sensor adaptation status/range both on idle and off idle can be affected oh ya does the ECU control timing advances depending on the program and what all these different sensors have something to do with it also.
oh and them **** secondary throttle plate positions sensors got to be in with something whether you have pulled them or not the do affect air/fuel mixture and flow or they would not have the secondary throttle sensor at all.

just bouncing a few thoughts around
I think it is the TPS mine has been fine for over 2500 miles now since the new TPS
I am not like everyone my bike *****es if I don't thrash it, so I please her every day I take her out! She likes it ruff :twisted::twisted:
At 28000 miles in less than two years I would have to say she holds her water well :lol: :lol:

Owl, I had this exact problem , missing and farting at a steady throttle about 2-3k rpm, it was brought on by me messing with the base idle screw to get a better idle when cold. I put it back to where it was and its ok now, has the base idle throttle stop been altered at all? it changes the TPS position.

 

[owl]

Steve, don't even know where the base idle screw is, or what it looks like
