http://home.earthlink.net/~gellett/400ex.htm Remember to add RPMS for rev boxes and to put your tire size in. Also i think red line for the 400ex is about 9100-9200 rpms correct me if im wrong.I thought this was pretty cool i found it on this site awhile ago and saved it so everyone could use it.

Its always nice to know if you dont know much about gearing and how it works.
