Have a 2016 can am rene 850xxc with about 10 hours and 110 miles.
Had a half of tank left from riding about 3 months back, top the tank with new gas before the ride. Only used up about a quarter tank .Quad ran great till the end of the ride I started to loss power in the throttle. Quad never had any issues prior.
Muffler sounded different as well.
I hit the throttle to 100 percent and quad took a while to respond.
No codes on dash. Could this be bad gas, spark plugs or fuel pump?

Could be all the above but being it had older gas in it to begin with i would start there and drain and flush the tank.  i would also buy a few new fuel filters and change it out. Bad gas can cause all kinds of problems fouling plugs is one of them so i would pull them and check to see how they look " post a pic of them if you can". after every thing is drained and cleaned i would also run some sea foam threw the system. let us know how it turns out.

Finally had a free min to take a look at the quad. Pumped out gas and replaced with new gas also added seafoam. Ran the quad for a while still felt under powered.
I removed the plastics to get to the spark plugs, right side was much easier then left.
Left side I had to remove the heat shield.
I posted the picture of the right spark plug.
Left spark plug I didn't remove just yet because I ran out of time but I think the left side is fine. I was able to start the quad with just left plug so that's why I think that's the good plug however I will check it was well.
Any idea why the plug went bad?

Those plugs arent bad, They look a little rich, but not bad.

When you jab the throttle does it fall on it's face?
