the chain i had before worked great, but the master link broke so i was hoping to buy a new master link and have it working again. the old master link must have been stretched because the new one won't fit. i just plan to order a new chain but since there is an extended swingarm i dont know how big to get it. the old chain has 100 links (including the master link) and its too small. how big should i go and where can i get one cheap?
