I have a Polaris 2 stroke with some rattling coming from engine. I have took 2 videos that way I can get some confirmation if this could be the cause of bedding top end rebuild.

I noticed the noise about 2 weeks ago but recently thought about what it could be.

this 2 stroke hasn’t been rebuilt since it came off the dealership floor in 1997. I am expecting it finally needs a rebuild but I’m gonna let you guys decide.

the noise I’m referring to is pretty much the only noise you can here in the video, you can barely here the detonation in the video so don’t confuse it.
