Xp 1000 transmission output shaft gear broke!

Has anyone else had this issue? Last week I had the highlifter gear reduction and turner dual reverse chain installed and went out riding this weekend and going thru a semi good mud hole just a herd a loud pop and then it sounded like home gears where grinding in the transmission. I was able to make it back to the main trail using my winch and 2wd then noticed that the front prop shaft wasn’t spinning. When the bike is off I can turn the front drive shaft 180 deg each direction before it stops witch makes me think it is the bevel gear on the output shaft.

I have searched the forum and didn’t see anyone else with this issue as I am now thinking these bikes have to much power for the drivetrain.
