Hello I just bought a 2005 ttr250 with a ffm pipe, an it is running me in circles.
it has fresh fluids, new air filter an battery, the bike starts right up no problem but after about 45 min or so of slow trail riding it begins to bog out an dies. It will only start with the choke on an them idles high as the sky an choke or not you cannot touch the throttle without it killing it. If it sits for 2 hours or so starts right back up just fine. Could this be a jetting issue, carb?? any help would be appriciated
