Yep, I ran them in 2 ops on the lathe.  First I did the front radii and ID which has a 3.5* taper from the opening radius down to the throttle body, the second op faced off the back and did the external shape as well as the counterbore that fits over the throttle body.  That is the nice thing about cnc, with a good program and set up you can make parts that are extremely close to being the same.

If your planning engine mods extra to the 180 re-phase I would fit a second front rotor.
Although I haven't done anything with XS650's for a while, 800-840 conversion with long rods (Honda CR500) is always good for a high torque motor  ;)
I really like the Megasquirt idea, been following Bowling and Grippo for many years (from the time before there was even a kit)

Engine work will depend on budget.  I'd like to do a long rod 750, but it might just get a rephase.

  Megasquirt isn't too bad to deal with.  I have a ms2 set up on my triumph spitfire running a Toyota 4age with ITBs.  Without that experience I would probably be more apprehensive about going this route.  I figure if I can get the stock engine running in MS, then do a rephase and change settings to adapt it'll be simpler as well as giving a base map for both set ups.

Well, it doesn't look like much but the rear seat mount is installed. I'm using 1 of these https://m.ebay.com/itm/Silver-Universal-Push-Button-Billet-Hood-Pin-Lock-Clip-Kits-Auto-Car-Quick-Latch-/182792166421?nav=SEARCH

I think it looks pretty good.  It is made of aluminum, and works well so far.

I also threw the air filters on to see how it looks.

I like the quick release push pin thing, probably get a few when I have some cash in Paypal  ;D

Yeah, the little push button is pretty cool, and they do have them with different diameters.  I don't think I would trust it as a hood pin, but for a seat, or side panel hold down it'll work as well as a dzus.

Working on a tedious part, the wiring.  To do that I'm using a bunch of CAD( cardboard aided design).  So far I have where fuse boxes, relays, ecu and battery will sit figured out, and have a cardboard template for the pan done.  Waiting on solder and shrink wrap to really run wires.

No picture for this update, I spent a decent amount of time making a rotor adapter to line things up on the rear brake.  Then found out the rotor bolt pattern was too big, and the adapter hit the caliper before the axle lined up.  So now waiting on a different rotor to make a new adapter.
