    Talking Throttle Sputter / Poor Response / Fuel Issue / Fuel Pump / Fuel Filter

    Wanted to thank everyone out there for all the good information regarding this topic. Never would have thought about taking the ignition off and removing the back cover to see if the plastic piece inside is cracked causing an issue only at a certain rpm. Also saw the posts about checking the connection from the Now to what my was / is doing. First I thought it was a dirty fuel filter. Sputtering at 4K RPM in third gear. I was going to get to it eventually but trying to come home from work and she started to sputter above 2K rpm I knew I had to do something. I nursed it home and realized what riding a motorcycle like a normal person must feel like. :yikes: She has the power commander with cobra pipes and K&N air filters. Changed the spark plugs with the OEM plugs, cleaned and recharged the air filters and replaced the fuel pump and fuel filter. I though the Amazon Special for $65 fuel pump would do the trick. Well yes and no. I feel I have identified the problem but not completely solved it. She still has a sputter at 4500 - 5000 RPM in 3rd, 4th and 5th gear. Think my fuel pump is "you get what you pay for". Maybe the impeller is garbage or it would work great on a 750 or something but not the 9. Which brings me to my question thank you for hanging in there. I have seen the cost of just the fuel pump range anywhere from $250 to $375 and up.

    Does anyone out there had a good experience with where you purchased your fuel pump and might recommend a website?

    Thanks again and keep the shiny side up!

    :bigthumbsup:

    Have you tried diagnosing using the service manual? I would think if the fuel pump was acting up it would give you a code of some sort. You might have to go into the dealer mode to get more info.

    OEM for $245

    Will double check everything using the Service Manual again. If if roll the throttle normal no issues it is only when I drop a gear and hammer the throttle or shift up and hammer the throttle i get the sputter at 4500 - 5000 RPM. Thanks for the link. Have always had really good luck with Oneida Suzuki.

    New Pump installed and I think it got better our that may just myself telling me it got better to make myself feel better. 4500-5000 rpm engine sputters once or twice and then will start pulling again above 5K rpm. Not sure there is a harmonic vibration causing something fishy to go on. Think I am going to raise the white flag and take it to a Dealer for a "check and advise"
