i got a used 400ex with a hot cam in it and i dont know what one it is. the part number it says on it it hcdi no:07 anyone know if this is a one or a two? and also when matching up the marks on the crankshaft and the cam sprocket to remove the timing chain, the "t" mark on the crankshaft is not exactly lined up with the cut mark when the sprockets notches are? is this because of the hot cam? any info appreciated.
