i have a 2005 crf 450x. has fmf power bomb header, fmf 4.1 exhaust, uni filter, and rejetted carbs. i am posting this because the bike ran fine than it started to run rough. did a air filter change, oil change, new spark plug, and new battery. now is really running bad. wouldnt start unless i held in hot start lever a little. when running it back fires and coughs. even short flame out pipe. checking to see if valves out of adjustment and found.
intake@ leaftside 0.00
exhaust@ leftside 0.009
dont think this is good and would like some advice. have not done anything else. waiting for yourguys help.
