hi, guys

I find it hard to see TuonoV4 in my country.
So I have never seen a TuonoV4 engine.

I want to know how RSV4 and ToonoV4 engines are different.
These are the same cases.
Something's gonna be wrong.
Crank? Connected road? Head?
Overall, what's wrong?
If you've had a post before, you can link it to it.
If anyone knows, can you let me know?
Thank you.
