xr 500 timing?

i blew the headgasket out on my 1983 xr 500 last week. i ordered the gasket kit and the clymer manual to do the job. i got the gasket last week, but still no book.. i was chomping at the bit to get this thing back rolling so i went ahead and replaced the gasket. the issue i am having is timing. does anyone know the procedure to time the chain and camshaft? i zip tied the chain to the wheel, but it moved. i now it is pretty easy, does anone have any tips.. i wanna go ride. thanks.

Position the crank at TDC by lining up the marks on the flywheel(through the access holes), install the cam with the lobes facing down, and line up the lines on the cam sprocket with the adjacent gasket surface.

      Changing out my fork oil on a new to me 650l. What's generally recommended for stock springs and valving?

      So I don't seem to find my specific issue so here I am asking. 
      I have a 1997 Xr600r. It was recently re-jetted and has ran really well ever since until more recently it has begun to have this issue.
      Everything works fine. Kicks right away, nice and easy. Runs great, sounds great, purs. But when I'm downshifting and slowing down to a stop, if I let my hand off the throttle that's when it just dies. I found that I can counter this by lightly holding the throttle as I down shift (so I'm revving quite a bit during downshift).  But it hadn't done this before. 
      The only thing I've done that I suspect may have been an issue on my part was when I pulled out the engine to change the valve cover gasket and upon doing so perhaps when connecting the carb back to it, I may have missed something or made a crack in the boot? 
      Any ideas? Thanks

      Hello all,
      There's been a lot of talk about how to register a dirt bike in states that don't allow it.
      I just moved to North Carolina and for the first time in my life might be able to afford a bike. I've been dreaming about an XR650R for a long time, but they're not cheap. Plated bikes seem to be more expensive too. So here's my question, has anyone tried to plate a dirt bike by adding all the necessary features and having it inspected as a custom bike? Anyone know of another way I can plate an xr650 in NC?

      Hoping for some help before I throw in the towel and end it all!
      Engine starts fine, runs and idles well for +/- 10 minutes, but cuts out while riding once the engine warms up (175 - 185) and intermittently cuts out thereafter (any speed/gear). It will start up after 30 seconds or so (but won't run for long before dying again). No spurting or surging.. just dies.
      I've replaced CDI (twice), Spark plug, spark wire and coil, and most recently pulse generator. I do have a 41mm Flat side carb from a CRF (and it has more power than the old carb setup), breathing through a Uni filter. Also, sealed battery tender battery (hasn't shown low when trickle charged).
      What's next on the test/replace list? Stator maybe? Please help...
