Collected bike after new fuel thing fitted. Problem remains. Gutted. Same issue this morning as before: After collecting the bike yesterday I noticed that the low rev juddering throttle issue was still present, however I didn’t get an engine light on my way home, so that was good. This morning with the bike cold it started with no issue, however the same (Whilst cold) kangaroo juice behaviour of the engine, proper cut outs even at full throttle. As before this quickly abated as the engine got warm and was back to the normal juddering or hesitation when between 4500 to 5000 revs at about 30 KPH. And the icing on the cake of my morning was, about 5 mins before the end of my journey, the engine light came on again. I stopped and restarted the engine, which cleared the light, and I looked for the flashing of the engine light on restart to see if it gave me a blinking message. It didn’t appear to flash this time. Obviously if I get it on the way home, I’ll see if I can see a flashing message then. This is so depressing I’ve no idea what we might try next. Frankly I’m sick of thinking about it. Guess it’s time to ask Daelim for their next idea.

Daelim have sent a new Fuel pump sensor which I'm having fitted tomorrow. Hopefully that will sort it. Thanks to all who took the time to reply with ideas and info.

Thanks so much for that info Spanner, really appreciated. Daelim have finally come back to my Dealer (Raceways in Surrey Quays) to say that they think @intake manifold absolute pressure signal failure' so could be a faulty MAP sensor. That certainly would account for the throttle hesitations at low to mid rev's that I've been experiencing. Arranging to take the bike in so they can check. Thanks again. S.

Thanks both. I have asked my dealer to get in touch with Daelim, however thought I would mention it on here 8n case the symptoms sound like something obvious. Will look into Mil codes. Thanks again!

Have a weird issue with this bike. It's a year old and just had its 2nd service at 6000 kilometers. Before the service I had noticed that when riding with only low throttle, the engine seemed to stutter and lose power slightly. Every time I accelerated harder the problem disappeared. Mentioned it to the bike shop but they couldn't''t find an issue. Things suddenly got worse on Friday and this morning. So bike was not started over the weekend, this morning started as normal, but suffered the same issues I did on Friday. So initially even with the throttle at max the bike seemed to keep intermittently losing power. After riding for 5 mins the engine light came on. I stopped the bike straight away and turned the ignition off. Waited about 30 seconds and restarted. Engine light did not come on, and rest of the ride into work was fine with no more losing power at high revs and no engine light. I have to believe this is related to the issue I mentioned when I last brought the bike in for service, which was that I had losses of power at low speed/revs that went away when I increased the throttle. Does anyone have any idea what I might ask my dealer to look at as potential culprits? Thanks to all who reply.
