well I have to replace the camshaft an rockers on my xr650r. Found new oem camshaft assembly for 155 from ServiceHonda.com, but a stage 1 hotcam is only 165 from XRSOnly.com! Question is does anyone know if the hot cams is just the shaft or the whole assembly? Also my xr is a tagged motard that rides 95% on the street, would a stage 2 be even better? Or just stick with stock?
