998S Stutter between 2.5K & 5K rpm
 

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.

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 :D

hope you get it sorted soon though!!

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

Meant to say

Swopped the race ecu for std ecu and it still had the same stutter - that's with the PC disconnected....mmmm

Nearly as good as mine!!!

I will be on a gixer and Jon on an R1 :D

Tim - what is that.............. - the Darth Vader of the bike world..:-O

Lily - c u there....:-)

its luvly!!!

Nice - but a bit too........ stealth bomber.........for me

I like garish race paint jobs - white anyone.....:-)

Had a the same on mine at Portimao. Removed one of the shims from the ign pick up sensor. All ok after that. ;)

Just read your original post again. Mine was totally cutting out, then cutting in again. Sounds different to the problems you are having, sorry :(

Like this - sorry couldn't find a real bike just an anorak....

FE Thx

You have pm

Just get an R6! You know it makes sense ;)

TP - I have!!

I thought you just rented one. Or have you bought one, that's what I meant.

I'm really leaning that way now and getting a lot closer to being in a position to getting one hopefully. Watch this space over the next few months!

No - rented one for Portimao from FE....

Try before you buy...........:-)

Ahh ok, well that's a good idea I suppose. I'd just buy one but then I've ridden one before so I know what I want. You'll probably just want one.

And hopefully I'll have mine by the end of August! And race it next year, fingers crossed.

Oh, if I do get it before the next No Limits trip to Portimao I'll be well up for that!

ill give you 3000 fior the old 998...............:)

TP - Cash allowing & assuming I like it - I'll be doing Nov too......maybe with an R6 but more likely my 998 - but you never know!!

Andyb - in your dreams - that is one sweet bike (okay without the stutter....) - I'll let you have the STM evo 48t slipper & 54m ti system for 3k.....& only if you're nice......

i thought that was a good price beens its broke......although i aknowledge its not been ridden hard........:D

It's not broke.....just an annoying electical problem....

How can you say that after all the time we've spent on track together :-P

TP - one each:

They look good to me.............a bit white for me...but then I hear that' white is the new black (ie see Rattlers bike!!)

I better start saving

i noticed a road going 06 plate in blue at my local honda dealer, remus exhaust etc...........£4700........??

Stutter
 

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.

Just seen this.........

Thanks for the suggestion
