On my 2013 KX250F the bike all the sudden wants to cut in and out like it is starving for fuel. Problem started after I crashed awhile back and had to replace just the subframe and exhaust but nothing else. After I put the bike back together this is when I was having problems. Started off whenever I was half way through a moto the bike would just start missing like when I was at a steady half throttle and seemed like when the bike was hot the problem would occur. The bike still starts right up every time. After I put a couple more rides on it the problem got worse and now cuts in and out when 0 to half throttle right off when I warm the bike up. Even when the bike is warming up I can tell it's not right. I have checked for codes and the bike is code free. Went through throttle body and had injectors cleaned, new plug, and checked valve clearances, checked fuel pump and still nothing. If anyone can help I would appreciate some feedback! Need this bike back and running asap. Thanks!
