    Hi, My name is Milind. I ride the triumph street 765s 2019 Red model. Recently I found an issue when gradually increasing the throttle from 120 KMPH to 130KMPH (ZONE) there is a zone where the throttle is non-responsive. I need to wack open the throttle to take the bike out of that zone. This issue is not identifiable to the dealership and some of my riding buddies who are very hard riders so they don't find the difference.
    But something is surely wrong that nobody is able to identify. Could you please guide for what could e the next steps?

    Aside: I have an HP coarse Slipon. I am not sure if I started to encounter this issue after I got the aftermarket exhaust installed.

    A dyno run with a/f plotted may give you the answer.

    As stated above I think a spin on the dyno will reveal the issue much better than on road tests as they can measure the air/fuel ratios etc.

    I am not sure if I have a Dyno setup nearby. next month I have the annual service due, can I ask the Triumph guys to reset the MAP. Will this fix the issue?

    As said in another of your conversations , there is a flat spot in almost all motorcycle tunes ! It's to do with noise and emissions laws !
    Get "tuneecu" read your bike ECU mapping , you'll see exactly where and what I mean !!

    Nuffsaid ...

    I have a 765RS in my collection and I reckon there is a flat spot if I'm being picky, which I am, at about 7200 but hey ho who sits at this rpm on a 765?
    All the funs just over 10k so no issue to me :joy:
