heres my question I know the 420 and 428 sprockets are interchangable one way. am I right that the difference is only chain width. One of my builds has a 420 sprocket on engine and a 428 on the rear tire do I use the 420 chain or a 428 chain? Anyone??? Thanks Rick.
thanks joe I been told i can use a sprocket from a mid 60s cb/cl 160 on the lifan 125 Ill cross reference them tomorrow as well as consulting the micro-fish drawings. I know you can mix n match some chains and sprockets. I just couldnt remember which ones. Thanx again
