Spluttering ?

[SPCK111]

Hi all
Hi all
     Just got back from a trip to Holland and I seem to have a bit of a problem. But to be truthful I may have had it before I went away 😁  Sometimes when in a high gear at low speed (think of roundabouts  here) when I wind the throttle on, the bikes spits and farts and splutters like the engine is shutting off and on again quickly and then it takes accelerates. If I open then throttle more the problem is better but still there.  Did a service a short time ago with new oil, filter and air filter but the bikes been fine since then

Any ideas?   Thinking maybe new plugs. Bikes only just done 21K thou. More conteneient riding at speed. 😁

Mine hesitated a bit before new plugs then fine. They often get neglected because they are a pain to change.

It's hard to tell.  It could be plugs but on this bike they tend to last a long time.  I changed mine at around 60k miles.  Had no engine issues.  Could be a bad coil.  Could be bad gas.  Might be a partially clogged fuel filter in the gas pump that resides in the tank.

Mine does that if I'm in eco mode around town. Others have found that their's is smoother around town in eco.... weird!

That could be plugs breaking down under load with the lean mixture Eco mode ?

When I first bought mine, it would cough and splutter around the 2500-3000rpm range but only under load.

A new set of spark plugs cured that.

Could also be an injector...

You lot and you're Eco mode.  Mines a 2008!!  I put some injector cleaner in tank and filled it up and off I went.  Seems to have cured the problem. Has also made the engine a lot smoother which is nice. :)

Nope its still buggered.   So it's now in the shop having the plugs changed. Also has found a very very slight weeping of oil from the cam cover which is going onto the cam sensor which may be causing the sputtering issue.  And still only halfway through. 😩
