Hi, i hope someone here can help me.
I have a 03 crf450. I have tried newer stock bikes from friend (2006 YZF450, 2007 and 2009 CRF450 and 2008 and 2009 sxf450) and now i found that my 03 crf450 motor seems weak down low compare to the newer bike.
I have new piston and rings, a hot cam stage1, an fmf powercore silencer, new clutch, all valve are good.
All of these have help a littlle but my motor still not has strong.
I don't have any other 2003 crf450 here that i can compare to mine.
Any Idea ?
Thanks guy
