Im not sure how it could be a timing issue.
Here is what i would do is it getting gas this may be dumb but has happend to me is the gas on? If it is make sure its getting to the plug
Is it getting spark? And do a leak down test before riding, you should even do it before you start.

Take your carb boot off, squirt a little PREMIX in the carb, then try to start it.
If it starts then dies its a carb issue, if it doesn't start check to see if you've got spark.

Question, why did you need the re build, did it just wear out, or was it something drastic.

I feel that a leak down test is in order before you try anything else.

While you are waiting for your tester, if you suspect a timing issue, pull the flywheel off and check the woodruff key.

sounds to me like a spark issue. make sure you getting a healthy spark, if you are, then check to see if your S-plug is wet, if it is, then you are getting fuel if its not, then you got a fuel issue.

let us know, then we can diagnose other possible issues.
