Also, someone in this or maybe one of my other posts mentioned upgrading to an '08 or later shock and said it was cheap, but partzilla wants $400+ for either a pre-gen or post-gen (is that what the '08+ models are called?)

I think I need an intervention.
The idle mixture screws on the Ninja are fuel bleeds, so turning OUT provides a RICHER mixture. It may be possible that something like 1.5 turns out with a 40 Pilot is the exact same as something like 2.5 out with a 38 Pilot - not sure if there are any other factors going on.

Complete exhaust systems for the PreGens may be getting hard to find. The sound improves, and they are lighter, but there is a minimal performance increase with most.

The New Gen shocks are cheap used on ebay.

Nah - you are fine.
