Hey Barry, I used to have the same concern. I have had the badly bruised toes to prove it. At the risk of over-simplication, On my bike, I found that if the kicker is allowed to go down to the 3 oclock position, it never ever slips. The arm must go down quite far to get off the cam that holds the gears apart when the the arm is at rest. Once I got into that habbit, I never had a problem.

BTW I shipped your sprocket this morning.

Me again, talking to myself. Took the kicker mechanism apart and carefully
undercut just a tad the gear teeth that bolt to the mainshaft. Pretty crude but
seems to be effective and I didn't grind through the hardening. I think a stronger
spring would help things but again it is a weird shape , what was it about
Henderson and square section springs?

there is NO way that Henderson could have sold thousands of 4's mostly ridden
by donut chomping cops unless they came with a kickstart mechanism that
worked perfectly every time. today we are dealing with worn out and incorrectly
heat treated gears. does anyone make quality replacements or should I have
some made?
