Thanks, I'm enjoying the build process.  I just wish I could finish faster and get to riding.

Take your time. The more satisfying the build the more fun the ride afterwards.I hate it when I think if only I had done that part better. Great build so far  ;)

Looks great so far! I built a XS650 single shock tracker that I still ride all the time one of my favorites. I would love to do a rephase also but haven't had the time. What other engine mods do you plan on?

Biggest engine mod I plan is going microsquirt.  It'll cost about the same as a pamco and a set of flat slides.  But othwerwise I'm tempted to get the high ratio primary, OD 5th, rephase and 700-750 bore.  But it all takes time and money.  So at first I may be pretty darn stock on the engine and spend the money to revalve/spring the suspension.

I have a Pamco w/ign. advance on my bike works great. The microsquirt would be nice.  I used a set of Ninja 500 CVK carbs on my bike after rejetting them they work great really smooth power and drivability with this set up. I had a set of flat slides from Mike's XS on there originally but they are junk never could get them dialed in.

Awesome!  love your old Atlas lathe.  I've got a 6" Craftsman badged Atlas and it's a blast.

Yeah, in general in not a carb guy.  My 73 triumph spitfire is running megasquirt 2 with individual throttle bodies.

  Thanks, I've really gotten a lot of use out of the old atlas, at times I wish I had a bigger lathe so I could do more depth of cut and finish faster.  But work with what you have, it'll do great if you take your time.

A little progress today, contemplating possible upper shock mount.

No more jack stands.  It is now on normal bike stands front and rear with the rear shock supporting weight.
