xs1100 - automatic cam chain tension
The plug on the front of my cam chain tensioner popped out. The symptom? A stream of oil blowing back on the engine and turning into smoke. Also, when stopped the oil simply shot forward, landing on my brakes causing them to not work. Thats a lot of problems for such a small part.
Rather than buy a new plug I opted to install an automatic cam chain tensioner for around the same price. I got a used tensioner from a Yamaha raptor 660. Unlike the stock tensioner, this one automatically tightens and has a latch to prevent it from loosening. Additionally, it does not have a rubber plug, it is sealed with a copper washer which would never 'fall out' like my rubber plug did.
I did have to file the holes on the new tensioner slightly to get it to fit nicely. Installation was not bad but I did follow the recommended procedure and removed the cam cover and timing cover so I could verify the cam chain did not skip a link when the old tensioner was removed. It did not.
While I had the covers off I decided to check and correct the valve clearances. I also changed the engine oil and oil filter.
