Progress... keeping it simple.

Included in the pile of parts I got with the racebike was a Muzzy/Scorpion system I had cobbled together.  Made 72 hp on a dyno, so not bad for a stock engine.  Not sure how much hp it will make on the 2014 engine -- perhaps I should dyno it again, as you can see that a PCIII was part of the sale.  I think it includes the custom map that was made for this pipe, but all engines are different.  You can see the main exhaust mount under the frame, with the outrigger bracket bolted to the rearset.  Its a dogbone from a zx9R I had lying around.  Sounds pretty mean.
I had played with an aluminum undertray, as I thought I might be running a race tail.  However hotbodies no longer makes a race fairing, and Catalyst Composites has been bought by another company which relocated to Florida during Hurricane season.  The plan is to now run a stock seat and sidepanels, with some superbiker-style numberplates on the side.  The full retro look!  Note quickshifter -- that is another nice treat that came with the bike.  Also using a stock (heavy) battery for now.
I knew from experience that woodcraft rearsets and a versys swingarm do not play along well together, so after selling a pile of other fancy bits that I didn't need, I bought a thumbrake and mount.  It is an italian one (no, not Brembo), and needed some modification to fit on the bars properly and clear the tank.
Side view -- bought a new 520 mx chain.  Torsional strength is sufficient, and no O- or X-rings to mess with, collect grime or impact on the fluidity of the chain.  I bought some rivet links as well to replace the clip link that usually comes with these things.
Front view, flipped on the side for some reason.  LHS of numberplate (while looking at it) for tech stickers.  A nice cf fender came with the bike, and I'll install that once I do some work on the forks.
Idiot lights -- red (oil) on top, green (neutral) below.  Tach goes to 10,000 rpm, and I've set the shift light at 9500 -- still more room past that, but that is the hp peak for a stock ex650 engine, so no sense revving it past that point.
You can see the fork preload backed all the way out.  Even at this setting, I'm only getting 30mm of sag.  For my preference, I also think the fork oil weight is too thick.  Racing the Duke 690 this past season on soft stock settings (and no adjustability) showed me that softer is better for me at the bumpy Gimli track.  I think I have some stock springs, so those and some 5w oil is where I will start.  I've treated myself to some proper fork tools (a spring compressor and rod to assist in bleeding the fork) so that will be a winter project as well.  Running the higher bars (vs clipons) puts far less weight over the front which also contributes to the amount of static sag I am getting.
