Bike's back - an update

The rev problem is a vacuum leak.  Either he didn't get the intake
boots on securely or he left a cap off of the synchronization inlets,
like the one the tank vacuum tube feeds off of.  Find that problem and
you'll probably find most of the running problems.  If it's not
obvious, spray some WD 40 into each one of the intake boots until the
engine rev's up, that's the one that is leaking.
