Ask me how I know.
Yeah, I remember that post – at which mileage did that happen? My Nixie started to rattle softly at 70.000km – I changed the tensioner, but to no avail, the rattle continued. At about 98.000 km the rattle became so unpleasant that I tried massout’s tensioner fix – and the rattling was gone. It must have been shortly before that I noticed a lack of power for the first time. I credited the high mileage, but as it turns out now, it could have been the timing of the cams. As soon as I got a new cam chain I can tell if full power is regained.
