I know this is an issue that has beat to death. But I have been searching and I can't come up with a definitive answer. I purchased a hotcam # 4044-1e. It hasen't shown up on my door step yet. Hotcams claims that the only differance between the YZF cam (#4022-1e) and the WRF cam (#4044-1e) is the pin for the autodecomp. I have an 05 wr450f. Has any won out their installed just the 4044-1e or the 4022-1e and seen a noticeable proformance gain? If I'm not gonna see a gain I will just send it back before I install it. The reason I went with the hotcam was #1 it was about $50 cheaper then the stock YZF cam. #2 the WRF hotcam is desigened to work properly with the WRF autodecomp and the stock YZF is not. Thanks, Rich.
