[Chef]

My 998S has developed a stutter between 2.5k & 5K rpm

Happens on open & constant throttle - okay before & after....

All electrical system short of replacing the loom has been checked - all fine

Just had a 12k service etc

Bit gutted as can't take to Park Algar now as needs to be dropped off on Sunday

Any ideas.......

Thx in advance

You know it makes sense;


Sorry mate, couldn't resist

Sounds like fuelling to me, check Pc if you run one also injectors & TPS.

[Chef]

Tim - check your mobile - the R6 is booked!!!! as are the pirelli diablo supercorsas, paddock stands etc etc

Bring it on

Chaz - PC has been checked & disconnected

What is TPS...

Thx

[twpd]

Throttle position sensor.

[Lily]

Nice one mister, you can play with us other traitors on non Ducatis

hope you get it sorted soon though!!

[Chef]

TPS (now I know what it is!!) has been checked too....:-)

Not sure injectors have - is that part of a 12k service....

Lily - I know!! - what are you on.......

Was think of getting an ex BSS R6 late last year.....then the credit crunch hit.............mmmmmmmmm.........be a good chance to try one out

Ta everyone

Oi - Tim - do you like my new avatar...........:-D

Had a similar problem on 996 last year and finally tracked it down to a split in the rubber fuel line directly after the pump. This means going into the tank but you can combine it with a fuel filter change which is how I found the problem.

Hope this helps.

[bradders]

wouldnt fuel filter chnage be part of a 12k service? in which case maybe moving things made it worse

Good suggestion! This reminds me of a chat I had with Ducati John the other week as he was sorting a 996 or similar with just that problem at the time. Apparently it is quite common and is only a 20 minute job to fix.
