I have a CRF450X 06 and installed the 1xInternational Stage 2 Performance Kit. As per instructions have placed clip in 4th position, set full mix screw at 2 turns, replaced main jet with 162 supplied and leak jet with 65. Pinke wire has been moved to empty location rather then cut. I also cut the air-box as outlined and installed a Pro Circuit T4 Stainless pipe and silencer. I have lots of popping when the bike is rev'ed up and the pipe is getting nearly white hot after running for 5-10 minutes in idle. Seems to me that the pipe is getting to hot and the popping is a problem. Does any one have any suggestions
