Cbr600 cutting out when pulling away...

There is a light tick, which could be normal, i have nothing to compare it against as its my first bike. A little online reading suggests the "F4" gets the clearances done around 16k.
Light tick is most likely the tensioners. They're s
t. Even new mine ticked.A raspy tick which settles when its warm can be in the internals of the exhaust which I'm reliably told have small plates inside which break up.

Not knowing the history of the Plugs, it'd be worth changing them out as it's a quick and easy fix. Fingers crossed that'll sort it but it might also be gunk from the tank in one of the carbs. Have you checked the fuel filter to see if there's signs of particles or gunk in there??
I'm willing to bet the plugs have never been changed. I haven't checked anything yet. BuzzBravado said:
UPDATE:
I thought i should post the fix since so many OP's never come back to say what the issue was..... I taken the plugs out which looked perfectly fine, but changed them anyway. Now runs so much nicer and doesn't cut out. Start with the obvious eh.
Glad its working. I thought i should post the fix since so many OP's never come back to say what the issue was..... I taken the plugs out which looked perfectly fine, but changed them anyway. Now runs so much nicer and doesn't cut out. Start with the obvious eh.
I have the same to do on my ninja over the holidays, exact same problem, seems to only want to run on 3 when on tick over, flat spots, pick revs up then works fine.
Think it'll be a case of checking leads, plugs, fuel filter, lines, gum in tank then the carbs. These were done 2 years ago, could need done again, but what makes me think its a plug or lead like yours is that it just happened when it was getting used regularly, not after it sat up for so long. So used for 60 miles a day 3 or 4 times a week then one day just started it.
That said I did the leads and plugs the same time the carbs were done so probably a sticking carb jet. who knows I need to bother my arse to look at it.
I've always just replaced ht leads and plugs as its only 20 quid or so. Is it worth testing them? if so how...
Mines was coils straight onto the plugs, so no HT leads. On one plug there was corrosion on the plug where it connects to the coil so that may have been enough to cause an issue. Although my plugs looked fine and were still gaped correctly, i would guess they were original so 15 years old and that was enough to warrant replacement.
I also opened the bleed screws on each carb bowl to empty any water that might have been floating on the fuel. No idea if it helped any though.
I'm still waiting for the issue to re-appear as i cant believe the plugs could have caused all those symptoms, especially the revs dipping with a sharp throttle blip, but there you go.
