I´m having issues with my bike don´t want to keep revs I can only do bumb start and why it´s on need to give him extra revs so be able to keep him alive if I let go the throttle will die instantly. I went to a garage and was told it´s the throttle body I also called AA recovery for a second opinion they also confirmed that is the throttle body so I changed with new one but nothing actually happened so it´s not the throttle body. My mate have same bike as me and he had similar issue in the past so he suggested it my be the kill switch controller on the right next to the throttle so we change this as well, but still nothing changed, after that was thinking it my be the starter relay because I put my heated grips and phone charger connect to it so I replaced and still nothing. I just wondering if someone else had similar issue before I don´t want to keep buying parts which are actually not needed for the moment, just wondering what to do if someone can help please. When do bumb start and start running their is no issues at all the issue is only when let go the throttle.
