My 400ex seems to be ticking, so i was under the assumption it was the valves out of spec. Thought of just bringing it in to get worked on, but shop rates are between $90-$120 an hour here which is ridiculous.
I did some research and some say it could be the timing chain tensioner? I have auto experience and when tensioners go bad, the timing chain will rattle or tap in the same fashion. I figured I could replace it myself, but I don’t really want to tear the whole motor down. There is no smoke and from what I can tell, no loss of power or stalling (timing is still intact)
I’m going to tackle the valve adjustment and replace the cam chain tensioner myself but I can’t find too much information on a step-by-step on how to replace the tensioner.
this is how it is positioned on the outside of the motor on the 400ex:
my question is, can you simply unbolt it from the motor and pop the new one in? Obviously draining the oil first.
Any input is greatly appreciated! need to get her ready for some snowy street riding :icon_ devil::icon_ devil:
