I have searched the forum and cannot find a straight answer to my question. I bought my 2001 426 6 weeks ago with a stock chain and 13/49 sprockets. Well the last few rides have continued to tater the stocker and I am well due. The previous owner gave me a new Regina Oring that he bought with the bike and it is a 114. Can I fit a 13/51 under this chain? If not I will go 13/50. I need to make this order soon so any help would be appreciated.
