It is easier and cheaper but...

Most reviews from those that installed the SE primary kit have said that it is too much for the street on anything other than a bar hopper. It is something near 3.70 instead of 3.37. 3.37 = about 200 rpm increase at 60MPH. 3.70 is much higher. Depends what you want, how much highway riding, etc.

Do a search on 3.37 and see all the posts about it with RPMs, part numbers, ease of installation, etc.
