Title: Spluttering ?
Post by: SPCK111 on September 29, 2015, 12:43:15 AM
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. 😩

Yeaaaa.  Did the trick.  New plugs and a cleaning of the from cam sensor. 😁👍

Interesting...I understand how the plugs may have helped but the front cam sensor?  Never heard of that as causing any kind of issue other than an oil leak.  And how do you clean it?  If anything, it's bathed in oil.  I've had them fail on a car and it caused hard starting when hot.  Car ran fine with it like that once started.  No sputtering.  I did some searching on cam shaft sensors and it's either bad or working.  A bad sensor can cause rough running.  I didn't see anything on cleaning them.  The sensor itself is self contained and works magnetically I believe.    I think them cleaning it made them feel better but I don't think it had anything to do with your issue unless they actually replaced it.

There was a very slight misting of oil on the cam sensor electrical connection on the outside of the cam sensor at the fromt of the cam cover from a very very small weep from the cam cover gasket. This may and I say may have got into the connection and caused problems so they just cleaned off the electrical connection. Probably not but really I'm just glad the bloody things fixed. 😁

I know that feeling..  We've had trouble with the front sensor leaking oil and replacing the o-ring usually takes care of it.  A bad electrical connection doesn't help.  Glad you got it sorted.

So now having done some digging on the cam cover seal apparently it's a common problem due to the cam tightening bolts shoulders not allowing he bolts to tighten down enough to squeez he cam cover down. Apparently some thicker washers is the answer.  Any else heard of this?   Mine so little I'm  not bothered at the moment but just thought I'd ask. Reports of the seal leaking at 8k which is ridiculous.

This cam sensor, it is the one in the front?  If so, it's an o-ring seal not a gasket as far as I know.  From what I understand, you can replace the o-ring with the Kwackers part but it will still leak.  One of our members has sourced another o-ring that fits a bit tighter.  I've actually got that o-ring and am going to fit it at some point this winter.   Let me see what I can find on our site about it...   I'll update this with the link... 

Here it is..  http://www.zggtr.org/index.php?topic=13866.0

Actually let me check that Kwackers number and see if it's changed at all over the years.  Ok, it's 92055-1639 and it's found under the fuel injection fiche.   It has not changed through the 2015 models...  http://www.ronayers.com/oemparts/a/kaw/500b58fef8700223e4796c24/fuel-injection

Yep It's the one at the front but the weep seems to be along the leading edge of the cam cover. Very little oil and no fresh oil and it seems encrusted with road grime/grit and I can see no fresh oil anywhere only traces of old. May well be the cam sensor o ring weeping and the wind blowing it sideways along the cam cover when riding at some point

Cheers mate thanks.
