being hard to kick is an indication you have good compression.
your inability to kick start is common with an electronic ignition. they are more picky than points. try setting the static timing with the timing mark in the left side of the timing hole. this results in about a 4 degree retard and should help.
even with this, though, if you can't get a good stroke on the kicker, you will still have issues. maybe it's your technique?
with the bike on the side stank, hold the bars and place your left knee on the seat.
give the carb a couple of squirts with the throttle and, with the ignition off, stroke the kicker up to the top of it's stroke and, with all your weight, kick it through 1 time.
give then carb another squirt with the throttle, pull the choke on full, turn the ignition on and, with all your weight, kick it through again while holding the throttle wide open.
after the bike starts, release the throttle and adjust the choke to the fast idle position until it warms up, then turn the choke off.
your kickstart is a leftover from Harleys 4-speed tranny's from Shovelhead days. if the battery is too low to use the electric start, you will not be able to kickstart the bike either.
it's cool and.....basically useless.
compression ratio on all EVO's is 8.5:1, stock.
if you decide to convert to points, set them the same way you did on the Ironhead or the Pan and remember, the electronic ignitions use a 3 ohm coil. if you convert to points, as I am sure you are aware, you will need a 5 ohm coil as well as the point conversion.
