    Hey Guys. This has happened twice now. When stuck in stop/go summer traffic my Visions engine RPMs rise and stays around 1500-1600 RPM's and the RPM's surge. Victory First time this happened last summer I turned the bike off several times and barely got it started again. When it happened again this week I did not turn my bike off to avoid the starting issue. Bike seems unhappy when this happens. Not a battery issue. Still using the same battery I was using last year. Works fine ever other time. Even after moving again the bikes RPM's stay high and only seems to get better after been put away for the night. Where should I start? Vacuum line?...Throttle body?...plugs?... I am planning on doing a full tune-up soon (throttle body cleaning, oil, plugs, air filter, etc).

    no throttle body to clean. Add plug wires to your list.
    So just how old is battery 3 or 5 years old.
    Get a hold of Rylan he can tell you more then us guessers

    I got stuck in some very hot stop and go traffic on vacation once. Finally was able to exit to take a much needed break. When we were ready to take off, bike would turn over strong but not start.
    Eventually it started and all ok.
    After inquiring about it on here, it was brought up that a few have experienced what acts like a vapor lock condition.
    I don't recall having the RPM issue you had tho.

    RPM surging could be a vacuum leak.

    Loose batt connections / bad batt can also cause the RPM surge.

    Really need to put a wrench on the batt terminals NOT just wiggle with fingers.

    Agree with @Trout . Also get your battery load tested and if you need to just replace it, heat can really screw with a battery that is not 100%.

    Me Breezer. Welcome.
    Have you done any modifications to your bike ? Is it stock. Let us know so we can help better. You can put it in your signature.
    If you don’t have a fuel tuner and you ride in stop and go a lot in a warm climate then I would get one. Even a stock motorcycle will benefit from a tune with a PCV or another popular tuner. Dyno tune is a good idea when installing a PCV.
    I’m not suggesting you hot rod the bike although cams, exhaust and free breathing intake certainly add to the experience of a great running Victory. I’m suggesting the fuel tuner to simply run the motor cooler and get it away from that dreaded stock / EPA lean tune that so many still complain about. The fix is easy. The benefits are long lasting.

    As a number have said above, check the battery. It amazes me how many good batteries have been bad.

    But you can test for vacuum leak around the boots by spraying wd40 around them at idle. If the RPM's change you have a leak. There are tons of videos on how to check this.

    Let us know what you find.

    Thanks for the great responses guys. I have had the bike for two year and was told by the original owner the battery was about a year old, so 3 year old battery if told correctly. I will check these terminals better and will check the battery load. There has been no modifications to the bike except the upgrade Victory Exhaust system (stage 1 i guess?) This has only happened twice, but got me paranoid when I get into traffic. Took the bike out today in 95 degree Florida weather with moderate stop go traffic and no issues. This has only happened when traffic is a crawl for an extended time. I'm not running a temp gauge so no idea what the bike temp is getting up to, by no warning or indicator lights are coming on. The bike has 9,000 miles if this helps. Will has plug wires to my tune-up and will check the vacuum lines with conducting the tune-up. Thanks again. Great tips!

    One of my favorite camp spots is just North of you in Alabama.
    You're about 5 to 6 hours from me.

    now that we know where you live. The top tuner in the southern part of the country is Kevinx. He can do more for you then any of us hear. Hes fair priced and honest.
