    Jetting 05 crf450x with mods.

    I purchase the jetting kit and installed the Red marked neddle to 4th from top groove, installed the #170 main jet, did the smog engine block of kit, and installed a Big Gun EVOX slip on exhaust. The bike starts fine, idles great, and takes off fine except for the very top end it sputters. Is there a rev limiter on the CRF450X in 05 or is the main jet this issue??? Thanks, Mike
