in my 79 z50R I put a lifan 110 The sprocket on the lifan engine was bigger than the honda engine and the chain didn't seem to fit too well plus the chain was rusted so i need a new one. Since the sprocket is bigger should i go for a CRF50 chain length of 78 links, or the stock 76 for the z50. I don't know if two links make that much difference but I don't know too much about chains other than the z50r chain was a 76 link 420 chain.

Buy a 100 link chain and cut it to fit properly. It eliminates the second-guessing and the "...well, maybe it'll fit, and maybe it won't..."

Sometimes those chinese motors have 428 size front sprockets on them and you have to change it to a 420.
