Chef · 02-Apr-2009, 09:45

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

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

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

Throttle position sensor.

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

Chef · 02-Apr-2009, 12:04

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

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.

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.
