Motorcycle Repair: stage 2 kit, stage 2, stage 1

Question
I have a 1998 FLHTCI ANNV. I was thinking about a stage 2 kit. I think around $700.I have the stage 1 kit now. Do you think the stage 2 kit is worth it.  

Answer
Since you already have a stage 1 kit and are planning on installing a state 2 kit you will only get a increase of around 5% from one to the other. In the range that you will probably be riding (2500-3000 RPM) you are not going to see much of a difference. This is not much for $700.
So to answer your question, no I dont think it is worth it.
Good luck and happy riding
Mike
