I’m new working on a kymco agility 50cc 2016 , I put a tight belt on my clutch and variator, there was no slack and that time I didn’t know anything, just order a variator and clutch performance kit and slap everything on, when I start it had a loud grinding noise, I crank it over couple times to see we’re the problem is coming from, my hunch was the variator so I put the old variator and old belt, and start it up and ran good few secs and made that grinding binding noise, so I’m at point I give up and throw the bike away, plz help.
