Never rode a motorbike before just got a honda xr80r it needed a chaim adjuster. Got that and then 15min or so after riding the chain breaks. Called the place that put it on they said im big for that bike and i would always need to be adjusting the chain iam about 6ft. 200lbs. Is the info they gave me correct or did i need a new chain and sprockets as well and they just didnt tell me. Please help dont want to be discouraged and stop trying to learn.
