Does my V11 Sport have Swine Flu?

[jsciullo]

My '00 has suddenly started to sputter and choke on my ride home today. Nothing horrible. It did this a bit last year and then it went away. This was the first hot day I had it out this year but I dont know if heat has anything to do with it. It hiccups around 4k and 3k RPM on decelleration. Any suggestions?

Thanks,

Jim

Well, they do say these bikes are kind of pigs???

 

Um, my guess would be running a bit lean. Have you set your TPS lately? I've let mine sit for 4-5 months and it ran ok, so I don't know if I would attribute it to just bad gas, but you could run some seafoam through it?

 

Other thought- it could be vapor lock. Did it do this shortly after starting it hot?

jrt is right bad gas will make her hun a little rough. If it was me i would get fresh gas reset tps install new plugs and give her a run dont forget the valve adjustment either

Without knowing anything more -- coupla thoughts & Q's, Jim

 

How many miles on fuel filter? Air filter?

(Per JRT): Last TPS setting? (Per BT): Old gas? Last valve adjustment?

Does it only happen after well warmed up and/or after idling at traffic lights, or more or less all the time?

What engine intake/exhaust mod's, if any?

PC III? Map?

An exhaust leak can cause this to happen too.
