	Am I, a KX owner, 'one of the unlucky ones' with the rivet still
installed in my dist.? If I have to look to find out, where do I look?

	How much of a difference does the "warm, recently-run" engine factor
make? Can it be expressed in 10ths of mm?? Because most, if not all, of
my lifters move a lot more than 0.1! A few are capable of moving what
seems like a WHOLE mm OR MORE!! :-(   Tell me that a warm engine will
pump 'em up and make a huge difference....my engine has not been run in
two to three weeks, so it's quite cold. ;-)
