2016 Can-Am Outlander MAX XT 650
I remember an old maxima I had that one day suddenly started suffering from that "dancing" knocking sound, freaked me out. Low mileage engine, too. Many calamity scenarios played through my mind while trying to figure out just wtf the racket was.
Ended up being a faulty spark plug, electrode disappeared/wore away, causing the spark to jump n dance all around the combustion chamber, looking for the shortest distance to ground. New $10 plug did the trick. Maybe it's the same thing going on with your bike
My initial oil change was very positive. I could find nothing in the filter, and only light metal on the magnetic plug, and the oil was black, so I guess it was conventional oil.It really seemed like a detonation issue to me, especially the way it would come and go. I may have to look into the plug and wire a little more before I go pulling things apart, but the filings in the oil worry me. I don’t know what a first oil change looks like on these, and I’m not sure if this is the first change. I know it had an OEM filter in it, but that doesn’t mean much.
I haven't listened to this since you first posted it >7 days ago. WTF? It sounded great then. I just can't wrap my head around what might have happened since then. It will be interesting to follow this and learn what the hell happened.Didn’t have much time yesterday with the tail end of the storm heading our way. The bike wouldn’t go into park when I got it (that worried me) and it has absolutely no brakes. Battery was dead, but the deal was good and I was buying it basically site unseen... so I can’t complain. After a new battery, a little tweaking on the shift rod, some pressure washing and 1/4 of a bottle of HEET fuel drier... here’s where she stands now. This was taken about 30 mins before a tornado touched down about 2 miles from us. 😐
My 12 came with green coolantI was thinking something along those lines too... or possibly the coolant not reaching that cylinder. It has green coolant in it, does anyone know if that’s the way they came in ‘13? My ’21 has the orange coolant, just wondering if the PO changed the coolant for some reason and didn’t bleed the system properly after.
