Hello, this is my first post here but I have been impressed by the quality of information. I just ordered a new 1979 XL185S cam (14101-437-000) and when the order completed, it informed me that what is actually going to be shipped is an updated number (14101-437-010). Does any one know if this updated version is basically the same cam profile, or what may have been changed. if the new version is a different profile, then I will find an old used on on ebay. Thank you very much. Scott
