Question about Motorcycles
After I rev my bike, i hear a grinding noise coming from the top of my motor. It's a YZ 250, and the rings haven't been changed for over 20 hours. Could it have something to do with that? Need help soon.
If its coming from the top end its definitely the ring/piston stop riding it if you keep riding it, it will mess up way more then top end if you cant do it your self take it to a shop asap

Sounds like it needs to be split.
You could have a bent shift fork, or worn shift drum. This is not a "simple" job.
I've also seen where gears mesh chewed up or rounded off.
Get it opened up!

Testimonial: "thanks dude, ill see what it is "
Are you locating the rings on the locating pins?? Have you "gapped" the rings??
When you say locked up I assume you mean seized??
