whats this i hear about at dynojet kit?

[ChrisRl]

I'm new to the KLR list (own a KRL 250) and was reading at http://www.dualsport.org/cvcarb/index.html where references are often made to "the Dynojet kit". Is this some jet kit that allows you to modify the CV carb for better performance? Has anyone tried it and is it good? Where can I get some details on it from, order one etc. Lots of questions I know. Thanks, Chris.
