my engine is sputtering around the 4-5k rpm range. it's great before and after there. any ideas what's causing it?

thanks

 

[Daimler-Maybach]

nobody has any ideas? it's annoying. i would like to fix it

Hove you changed or added anything recently? How many miles does it have?

 

[Daimler-Maybach]

i put on a slip-on on, but it did it before then too, so that isn't it... there's only about 4k miles on the **** thing

 

[minoupak]

maybe you could try the TPS mod...does it sputter only when you are at WOT?

 

[Daimler-Maybach]

it only sputters at 4-5k range. 4.5-5k actually

 

[Angrysheep]

mine does it between 3 and 4k. super annoying.

i've adjusted the TPS and i have a slip on as well, and i cant remember when i started noticing it.

thinking maybe throttle body synch? bad fueling map? hell i have no idea.

post up if you figure anything out

How are the spark plugs?

Maybe dirty fuel injectors? Try some fuel cleaner.

My bike sometimes runs rough at idle and lower rpms, but usually by 4000 it's fine.

mine does the same thing tryed every thing still does it think its to do with the emission sh1 t suzuki put on the k7 onwards

it's so annoying. it makes for some rather unexpected accelerations and decelerations while i'm taking turns sometimes and sucks the big one. i'll try FI cleaner, but i don't think that's what it is. i don't see how, if it is the injectors, it wouldn't act like that all the time...

I also have an 07 and mine started doing the same thing. just like you not sure why. Just been living with it so far. I started down shifting to get rid of the sputters and runnung higher rpms a little longer.

Sounds like this may be a fairly common problem. Maybe it's a faulty TPS. Yamaha had a recall for faulty TPS units on the early FJR's.

Mine does it too, between 3800 and 4700... I just cruise at about 5k now, no sputters and the engine has the best tone too.

07 on suzuki put on crap for emissions which in my opinion ruined a good bike
